- Resource Allocation: Critics argue that the vast financial resources required for space missions could be redirected towards urgent global challenges such as poverty, healthcare, and climate change.
- Immediate Needs: With millions of people living in poverty, investing in social programs and infrastructure could yield immediate benefits for communities in need.
- Environmental Concerns: Addressing climate change requires significant investment in renewable energy, conservation efforts, and sustainable practices, which some believe should take precedence over space missions.
Ethical Considerations
- Moral Responsibility: There is a moral imperative to address human suffering and environmental degradation before venturing into space. Critics posit that spending on space exploration may reflect a lack of urgency regarding these issues.
- Long-term vs. Short-term: While space exploration can yield long-term scientific advancements, the short-term benefits of addressing Earth's problems are often prioritized by those advocating for the reallocation of funds.
Conclusion
In summary, the argument against allocating resources to space exploration centers on the pressing needs of humanity and the ethical implications of prioritizing space over immediate terrestrial challenges. Balancing the allure of space with the realities on Earth remains a critical discourse in the field of exploration.

The author discusses the beliefs of Emerson, Thoreau, Hawthorne, Melville, and Whitman, focusing on their humanistic perspective. These writers share the belief that humans are the spiritual center of the universe and that understanding the nature, history, and cosmos depends on understanding humanity itself. They reject the exclusive principles of a deity or brute matter and prefer to explain the world in terms of human experience. The Transcendentalist principle asserts that the structure of the universe mirrors the structure of the individual self, emphasizing that all knowledge begins with self-knowledge.
This humanistic perspective is universalized, emphasizing the universal nature of humanity rather than specific cultural identities. It transcends time, space, birth, and talent. The writers envision the individual as part of a greater whole. They believe that individual virtue and happiness depend on the self-realization achieved through the harmonious reconciliation of two psychological tendencies: the self-asserting impulse to remain unique and separate, and the self-transcending impulse to embrace the world and become one with it.
These conflicting impulses can be observed in the democratic ethic, where the democratic self faces the tension between individual liberty and the duty to society. Another shared belief among these writers is the conviction that intuition and imagination provide a more reliable path to truth than abstract logic or scientific methods. They emphasize introspection and view experience as symbolic, considering the inner world of individual psychology as the key to understanding external nature.
The writers have faith in the power of imagination and see themselves as practitioners of imagination. They perceive the writer as a seer and have unwavering confidence in their own moral and metaphysical insights.
Q. According to the passage, the humanistic perspective of the five writers presupposes which of the
following?
I)The structures of the universe can be discovered through self-knowledge.
II)The world can be explained in terms of humanity

Recent years have presented both opportunities and risks for minority-owned businesses in the United States. Activists have long argued that the lack of access to substantial contracts and subcontracts from large companies hinders the establishment of minority businesses. In response to this concern, Congress has mandated that businesses awarded federal contracts over $500,000 make an effort to find minority subcontractors and document their efforts with the government. Some federal and local agencies have even set specific percentage goals for allocating parts of public works contracts to minority enterprises. Corporate response to these initiatives has been significant, with corporate contracts with minority businesses increasing from $77 million to $1.1 billion in 1977. Projections indicate that corporate contracts with minority businesses will surpass $3 billion per year in the early 1980s. While this patronage is promising for minority businesses, it also poses risks. Firstly, small minority firms may risk expanding too quickly and becoming financially overextended. Unlike large businesses, they often need to make substantial investments in infrastructure and staff to fulfill subcontracted work, making them vulnerable to reduced subcontracts and crippling fixed expenses. Secondly, white-owned companies may seek to capitalize on the increased apportionments by forming joint ventures with minority-owned businesses. While legitimate joint ventures can be formed, there is a risk of white backers using minority-owned concerns as fronts to obtain subcontracts. Thirdly, minority enterprises that rely heavily on a single large corporate customer run the danger of becoming dependent. Fierce competition from larger, established companies makes it challenging for small businesses to broaden their customer bases. When these firms have guaranteed orders from a single benefactor, they may become complacent and struggle to seek new opportunities.
Q. It can be inferred from the passage that, compared with the requirements of law, thepercentage goals set by "some federal and local agencies" are
  • a)
    more popular with large corporations
  • b)
    more specific
  • c)
    less controversial
  • d)
    less expensive to enforce
  • e)
    easier to comply with
Correct answer is option 'B'. Can you explain this answer?

Ayesha Joshi answered
The passage states that federal and local agencies have set specific percentage goals for apportioning parts of public works contracts to minority enterprises, indicating that these goals are more specific than the general requirements set by law.

The passage discusses the behavior and characteristics of the indigo bunting, a strongly territorial bird. The main mechanism for securing, defining, and defending a suitable breeding area in this species is through song. Only the strongest males can retain a good territory when population density is high, while the weakest males either do not breed or are forced onto poor or marginal territories. The male indigo bunting sings in his territory during the breeding season, producing melodic and rhythmic songs with distinct figures. These figures are reproduced consistently, with a limited variety despite the large frequency range and rapid changes in sound. The study found that male indigo buntings are capable of singing many more types of figures than they usually do, suggesting that they learn and copy figures from other buntings they hear. The ability to distinguish the songs of their own species from other species is important, as male indigo buntings did not respond to recordings of other bird species. Additionally, the passage explores the role of song figures in interspecies recognition and the importance of specific frequency ranges, duration limits, and intervals between figures. The passage concludes that there is a balance between song stability for species recognition and song variation for individual recognition.
Q. According to the passage, which of the following is true about the number and general natureof figures sung by the indigo bunting?
  • a)
    They are established at birth
  • b)
    They evolve slowly as the bird learns
  • c)
    They are learned from other indigo buntings.
  • d)
    They develop after the bird has been forced onto marginal breeding areas.
  • e)
    The gradually develop through contact with prospective mates
Correct answer is option 'C'. Can you explain this answer?

Ayesha Joshi answered
The passage mentions that male indigo buntings are capable of singing many more types of figures than they usually do, suggesting that they learn and copy figures from other buntings they hear singing.

In recent years, there has been a growing debate among scientists regarding the impact of climate change on global ecosystems. While the majority of scientists agree that human activities are contributing to the rise in global temperatures, there is still a minority of researchers who dispute this consensus. These skeptics argue that natural climate variability and other factors may be responsible for the observed changes, and they question the accuracy of climate models used to predict future trends.
One of the key arguments put forth by climate change skeptics is the historical variability of Earth's climate. They point to periods in the past when the planet experienced significant climate fluctuations without any human influence. According to these skeptics, this historical variability suggests that current changes in climate may also be part of a natural cycle and not solely caused by human actions.
Additionally, skeptics often criticize the use of climate models to make predictions about future climate scenarios. They argue that these models are based on simplified assumptions and may not accurately capture the complexity of Earth's climate system. Furthermore, they highlight instances where past predictions made by climate models have not aligned with actual observations, casting doubt on the reliability of future projections.
However, the scientific consensus on climate change remains strong. The Intergovernmental Panel on Climate Change (IPCC), a body of leading scientists from around the world, has consistently emphasized the role of human activities, particularly the burning of fossil fuels, in driving climate change. The IPCC's reports provide comprehensive assessments of the current state of knowledge and highlight the overwhelming evidence supporting human-induced climate change.
Critics argue that the consensus among scientists is influenced by political and ideological factors rather than scientific evidence. They suggest that scientists who support the consensus position receive more funding and recognition, while dissenting voices are marginalized. However, this claim is not substantiated by empirical evidence and overlooks the rigorous peer-review process that scientific research undergoes.
In conclusion, while there may be a minority of skeptics challenging the consensus on climate change, the weight of scientific evidence overwhelmingly supports the role of human activities in driving global warming. It is crucial to heed the warnings of scientists and take collective action to mitigate the impact of climate change on our planet.

The recent discoveries of white dwarfs, neutron stars, and black holes have been highly significant in the field of physics. These discoveries have posed a major challenge to physicists, comparable to the failure of classical mechanics. As stars go through their life cycle and exhaust their hydrogen and helium fuel, the balance between outer nuclear radiation pressure and gravitational force becomes disrupted, leading to contraction. During this contraction, a dense plasma is formed. If the star's mass is less than 1.4 times that of our sun, the contraction stops at a density of 1,000 tons per cubic inch, resulting in the formation of a white dwarf. However, if the star is more massive, the white dwarf cannot resist gravitational pressures, leading to a rapid collapse where all the star's nuclei are converted into a gas of free neutrons. Further gravitational compression occurs until a density of 10 tons per cubic inch is reached, resulting in the formation of a neutron star. If the star's mass is even greater, gravitational forces overwhelm the strong nuclear force, causing the neutrons to merge and form heavier particles. This collapse leads to the creation of unknown entities. The star continues to collapse until theories predict infinite density and infinitely small dimensions. Before this point, the surface gravitational force becomes so strong that nothing, not even light, can escape, resulting in the formation of a black hole. The gravitational collapse presents a fundamental challenge to physics, as current theories suggest seemingly impossible conditions like infinite density and infinitely small dimensions. This situation is reminiscent of the atomic structure paradox in the 1930s, which led to the development of quantum mechanics. Similarly, we may anticipate a significant advancement in our understanding of gravitational collapse.
Q. What happens if the original star's mass is more massive than a few solar masses during the collapse?
  • a)
    Formation of a white dwarf
  • b)
    Formation of a neutron star
  • c)
    Formation of a black hole
  • d)
    Formation of heavier hadrons
  • e)
    None of the above
Correct answer is option 'C'. Can you explain this answer?

Ayesha Joshi answered
The passage explains that if the original star's mass is more massive than a few solar masses, even the strong nuclear forces cannot resist the gravitational forces, leading to a collapse that results in the formation of a black hole.

Paleontologists have been intrigued by the fossil remains of the pterosaurs, the first flying vertebrates, for over two centuries. The challenges of powered flight and the true nature of these creatures, whether they were reptiles or birds, have been subjects of debate among scientists. However, it is generally accepted that pterosaurs were reptiles based on their skull, pelvis, and hind feet anatomy. Their wings, characterized by a greatly elongated fourth finger supporting a wing-like membrane, suggest they did not evolve into birds. Pterosaurs had a combination of bird-like and bat-like features in their overall structure and proportions, which is not surprising considering the aerodynamic constraints of flight in vertebrates.
Both pterosaurs and birds have hollow bones, reducing weight, but bird bones are reinforced internally. It is likely that pterosaurs had a coat of hair to insulate against heat loss and streamline their bodies during flight. The recent discovery of a pterosaur specimen covered in hair-like fossil material supports this hypothesis. The question of how pterosaurs became airborne has led to various suggestions, including launching themselves from cliffs, dropping from trees, or using updrafts from high waves. Each hypothesis has its limitations, such as the mismatch between pterosaur feet and bat feet for cliff launching and the potential difficulty of large pterosaurs landing in trees without damaging their wings.
Q. According to the passage, the skeleton of a pterosaur can be distinguished form that of a birdby the
  • a)
    size of its wingspan
  • b)
    presence of hollow spaces in its bones
  • c)
    anatomic origin of its wing strut
  • d)
    presence of hooklike projections on its hind feet
  • e)
    location of the shoulder joint joining the wind to its body
Correct answer is option 'C'. Can you explain this answer?

Ayesha Joshi answered
The passage states that the skeleton of a pterosaur can be distinguished from that of a bird by the anatomic origin of its wing strut, particularly the elongated fourth finger supporting the wing-like membrane.

The topic of climate change has gained significant attention in recent years as the impact of human activities on the environment becomes more evident. Climate change refers to long-term alterations in temperature and weather patterns across the globe. It is primarily caused by the release of greenhouse gases, such as carbon dioxide and methane, into the atmosphere. These gases trap heat from the sun, leading to a gradual rise in global temperatures known as global warming.
One of the main contributors to climate change is the burning of fossil fuels, which releases large amounts of carbon dioxide into the atmosphere. The combustion of coal, oil, and natural gas for electricity generation, transportation, and industrial processes accounts for a significant portion of greenhouse gas emissions. Deforestation also plays a role in climate change, as trees absorb carbon dioxide and release oxygen. When forests are cleared, the stored carbon is released back into the atmosphere.
The consequences of climate change are wide-ranging and pose significant challenges to both human and natural systems. Rising temperatures contribute to the melting of polar ice caps and glaciers, leading to a rise in sea levels. This, in turn, increases the risk of coastal flooding and erosion, threatening coastal communities and ecosystems. Changes in precipitation patterns result in more frequent and intense droughts, heatwaves, and storms, impacting agriculture, water resources, and public health. Furthermore, shifts in climate conditions can disrupt ecosystems, causing species extinction and affecting biodiversity.
Addressing climate change requires a multi-faceted approach that involves mitigation and adaptation strategies. Mitigation involves efforts to reduce greenhouse gas emissions and minimize the impact of human activities on the climate. This can be achieved through the transition to renewable energy sources, energy efficiency measures, and sustainable land use practices. Adaptation focuses on building resilience to the impacts of climate change, such as developing infrastructure to withstand extreme weather events and implementing strategies to protect vulnerable populations.
The urgency of addressing climate change has led to global initiatives and agreements, such as the Paris Agreement, which aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels. However, the successful implementation of climate change mitigation and adaptation measures requires collective action at the international, national, and individual levels.
Q. What role do renewable energy sources play in mitigating climate change?
  • a)

Certain examples of poetic justice found in medieval and Elizabethan literature have inspired twentieth-century scholars to seek out additional instances. However, these scholars have merely imposed a moral framework on victimized characters, justifying the injustices inflicted upon them in one way or another. They deny the innocence of the sufferers in a tragedy and hold them responsible for their tragic fates. Any wrongdoing on the part of a character is enough to subject them to critical scrutiny. For instance, there are lengthy essays analyzing the wrongdoings of Webster's Duchess of Malfi, who defied her brothers, and the behavior of Shakespeare's Desdemona, who disobeyed her father.
Yet it is worth remembering that Renaissance writer Matteo Bandello strongly objected to the unjustly severe punishments imposed on women for acts of disobedience, while men could commit similar acts with virtual impunity. Shakespeare, Chaucer, and Webster often enlist their readers to sympathize with their tragic heroines by portraying cruel injustices that evoke a sense of protest. Chaucer, in the Clerk's Tale, presents Griselda as a meek and gentle victim who does not criticize or rebel against her oppressive husband, Walter. This portrayal incites readers to support Griselda against Walter's tyranny. Thus, attempts to justify Walter's persecutions with historical and theological arguments contradict the intended effect on readers' sympathies in Chaucer's fable. Similarly, asserting that Webster's Duchess deserved torture and death because she chose to marry the man she loved and bear their children aligns with her tyrannical brothers and confuses the concept of poetic justice, which readers should endorse, with social injustices that Webster clearly condemns. In fact, Webster depicts his heroine as a courageous leader in resistance against tyranny, inspiring the audience to join her in opposing the cruelty and hypocritical morality of her brothers. In their own distinct ways, both Chaucer and Webster challenge injustice, advocate for the victims, and denounce the oppressors. The readers serve as a court of appeal for them, remaining free to render judgments based on evidence and common humanity. As the esteemed eighteenth-century scholar Samuel Johnson paraphrased, it is through the common sense and compassion of readers, uncorrupted by the characters and situations in medieval and Elizabethan literature, that these works, like any other literature, can be best evaluated.
Q. The author of the passage is primarily concerned with
  • a)
    reconciling opposing viewpoints

Throughout history, the debate surrounding the concept of free will has captivated philosophers, scientists, and theologians alike. Free will refers to the capacity of individuals to make choices that are not determined by external factors or predestined outcomes. It raises fundamental questions about human agency, moral responsibility, and the nature of causality. While some argue that free will is an essential aspect of human existence, others propose that our actions are predetermined by various factors, such as genetics, upbringing, and societal influences.
One argument against the existence of free will is the determinist perspective. Determinists posit that every event, including human actions, is causally determined by antecedent events and conditions. They argue that if one were to possess complete knowledge of all relevant factors, it would be possible to predict with certainty an individual's choices and behaviors. According to this viewpoint, free will is an illusion, as our actions are simply the result of prior causes, leaving no room for genuine choice or autonomy.
On the other hand, proponents of free will maintain that human beings possess the capacity to make choices that are not solely determined by external influences. They argue that consciousness, rationality, and introspection are key components of free will. While acknowledging the existence of certain constraints, such as biological and environmental factors, they assert that individuals have the ability to deliberate, weigh options, and make decisions that align with their values and desires.
The debate surrounding free will has important implications for various fields, including ethics, law, and psychology. It influences our understanding of moral responsibility and accountability, as well as the criminal justice system's approach to punishment and rehabilitation. Moreover, it raises profound questions about the nature of personal identity and the relationship between mind and body.
Q. The determinist perspective argues that:
  • a)
    Free will is an illusion
  • b)
    Human choices are influenced by genetics, upbringing, and societal factors
  • c)
    Consciousness and introspection play a crucial role in decision-making

Woodrow Wilson referred to the liberal concept of the economic market and expressed the belief that the free enterprise system is the most efficient economic system. According to Wilson, maximum freedom leads to maximum productivity, and the measure of our stability lies in our openness. This fascination with the ideal of maximum freedom has caused Americans to reject the traditional categories of settled possessiveness versus unsettling deprivation, the desire to retain versus the desire to seize, and the defense or attack of the status quo. In the United States, there is no status quo ante; our only "station" is the constant turning of a stationary wheel, spinning faster and faster. Our system is not based on property but on opportunity, which means it is rooted in mobility rather than stability. The more things change, the more rapidly the wheel turns, the more steadfast we become.
The conventional understanding of class politics consists of the Haves, who seek stability to preserve their possessions, and the Have-Nots, who desire a touch of instability and change to scramble for what they lack. However, Americans envision a condition where speculators, self-made individuals, and runners constantly seize the new opportunities provided by our land. These economic leaders, or front-runners, are seen as agents of change. On the other hand, those who are left behind, the nonstarters, seek stability and a strong referee to secure their position in the race, a regulating force to calm manic speculation, and an authority that can reset things from staggered starting lines. "Reform" in America has been ineffective because it can only imagine change through the extension of the metaphor of the race, including wider inclusion of competitors and giving a "piece of the action" to the disenfranchised. There is no attempt to call off the race, as our only stability comes from constant change.
According to the passage, the American legends do not honor the quiet work that fosters social interdependence and stability. There is no heroism attributed to office clerks or a stable industrial workforce, the people who actually make the system function. Being an employee is not a source of pride (Wilson called for a return to the time when everyone was an employer). Social workers are not praised or boasted about; they are viewed as a necessity. The empty boasts from the past make us ashamed of our present achievements, pushing us to try to forget or deny them, to distance ourselves. In this wonderland race we all must run, there is no honor, as everyone strives to win but no one ultimately succeeds because there is no end.
Q. The author sets off the word "Reform" with quotation marks in order to
  • a)
    emphasize its departure from the concept of settled possessiveness
  • b)
    show his support for a systematic program of change
  • c)
    underscore the flexibility and even amorphousness of United States society
  • d)
    indicate that the term was one of Wilson's favorites
  • e)
    assert that reform in the United States has not been fundamental
Correct answer is option 'E'. Can you explain this answer?

Ayesha Joshi answered
By using quotation marks around the word "Reform," the author indicates that reform in the United States has not been fundamental or transformative, as implied by the passage.

The passage discusses the behavior and characteristics of the indigo bunting, a strongly territorial bird. The main mechanism for securing, defining, and defending a suitable breeding area in this species is through song. Only the strongest males can retain a good territory when population density is high, while the weakest males either do not breed or are forced onto poor or marginal territories. The male indigo bunting sings in his territory during the breeding season, producing melodic and rhythmic songs with distinct figures. These figures are reproduced consistently, with a limited variety despite the large frequency range and rapid changes in sound. The study found that male indigo buntings are capable of singing many more types of figures than they usually do, suggesting that they learn and copy figures from other buntings they hear. The ability to distinguish the songs of their own species from other species is important, as male indigo buntings did not respond to recordings of other bird species. Additionally, the passage explores the role of song figures in interspecies recognition and the importance of specific frequency ranges, duration limits, and intervals between figures. The passage concludes that there is a balance between song stability for species recognition and song variation for individual recognition.
Q. According to the passage, the authors played a normal indigo bunting song backwards inorder to determine which of the following?
  • a)
    What are the limits of the frequency range that will provide recognition by the indigo bunting.
  • b)
    What is the time duration necessary for recognition by the indigo bunting?
  • c)
    How specific must a figure shape be for it to be recognized by the indigo bunting?
  • d)
    How does variation in the pacing of song figures?
  • e)
    Is the indigo bunting responding to cues other than those in the song figures?
Correct answer is option 'C'. Can you explain this answer?

Ayesha Joshi answered
The passage states that playing a normal song backward changed the detailed forms of the figures without altering frequency ranges or gross temporal features. Since the male indigo buntings responded almost fully to the backward song, it suggests that a wide range of figure shapes can evoke positive responses. This implies that a specific configuration is not essential for interspecies recognition, highlighting the importance of frequency range, duration limits, and spacing intervals in recognizing the figures.

What does the passage imply about the scientific consensus on climate change?
In recent years, there has been a growing debate among scientists regarding the impact of climate change on global ecosystems. While the majority of scientists agree that human activities are contributing to the rise in global temperatures, there is still a minority of researchers who dispute this consensus. These skeptics argue that natural climate variability and other factors may be responsible for the observed changes, and they question the accuracy of climate models used to predict future trends.
One of the key arguments put forth by climate change skeptics is the historical variability of Earth's climate. They point to periods in the past when the planet experienced significant climate fluctuations without any human influence. According to these skeptics, this historical variability suggests that current changes in climate may also be part of a natural cycle and not solely caused by human actions.
Additionally, skeptics often criticize the use of climate models to make predictions about future climate scenarios. They argue that these models are based on simplified assumptions and may not accurately capture the complexity of Earth's climate system. Furthermore, they highlight instances where past predictions made by climate models have not aligned with actual observations, casting doubt on the reliability of future projections.
However, the scientific consensus on climate change remains strong. The Intergovernmental Panel on Climate Change (IPCC), a body of leading scientists from around the world, has consistently emphasized the role of human activities, particularly the burning of fossil fuels, in driving climate change. The IPCC's reports provide comprehensive assessments of the current state of knowledge and highlight the overwhelming evidence supporting human-induced climate change.
Critics argue that the consensus among scientists is influenced by political and ideological factors rather than scientific evidence. They suggest that scientists who support the consensus position receive more funding and recognition, while dissenting voices are marginalized. However, this claim is not substantiated by empirical evidence and overlooks the rigorous peer-review process that scientific research undergoes.
In conclusion, while there may be a minority of skeptics challenging the consensus on climate change, the weight of scientific evidence overwhelmingly supports the role of human activities in driving global warming. It is crucial to heed the warnings of scientists and take collective action to mitigate the impact of climate change on our planet.
  • a)
    It is influenced by political and ideological factors.
  • b)
    It is based on empirical evidence and rigorous peer-review processes.
  • c)
    It disregards dissenting voices and marginalizes skeptics.
  • d)
    It primarily focuses on the historical variability of Earth's climate.
  • e)
    All of the above
Correct answer is option 'B'. Can you explain this answer?

The extent of suffering caused by labor market problems is a critical but contentious social policy question. Social statistics often exaggerate the level of hardship experienced. Unemployment today does not have the same severe consequences as in the 1930s when most jobless individuals were primary breadwinners, income levels were closer to subsistence, and social programs were lacking. Factors such as increased affluence, more dual-earner families, and improved social welfare have mitigated the impact of joblessness. Similarly, earnings and income data overstate hardship. Many individuals with low hourly earnings, including those near the minimum wage, come from relatively affluent families with multiple earners. Poverty statistics also do not accurately reflect labor market issues, as they mainly include the elderly, disabled, or individuals with family responsibilities who are not part of the labor force. However, social statistics also underestimate the hardship related to the labor market. Unemployment counts exclude fully employed workers with low wages, who still live in poverty. Low wages and repeated or prolonged unemployment often combine to undermine self-support. Additionally, the number of people experiencing joblessness at some point during the year is higher than the average monthly unemployment, with part-time workers and individuals wanting a job but not in the labor force. Furthermore, income transfers primarily focus on the elderly and dependent, neglecting the needs of the working poor. The contradictory evidence makes it uncertain whether the number of individuals suffering due to labor market problems is in the hundreds of thousands or tens of millions, and whether high levels of joblessness require job creation and economic stimulus. The existing poverty, employment, and earnings statistics are inadequate for measuring the consequences of labor market problems.
Q. The author contrasts the 1930's with the present in order to show that
  • a)
    more people were unemployed in the 1930's
  • b)
    unemployment now has less severe effects
  • c)
    social programs are more needed now
  • d)
    there now is a greater proportion of elderly and handicapped people among those in poverty
  • e)
    poverty has increased since the 1930's
Correct answer is option 'B'. Can you explain this answer?

Ayesha Joshi answered
The passage compares the present with the 1930s to illustrate that unemployment today does not have the same dire consequences as it did during the Great Depression. Factors such as increased affluence, dual-earner families, and improved social welfare have mitigated the effects of joblessness.

The topic of climate change has gained significant attention in recent years as the impact of human activities on the environment becomes more evident. Climate change refers to long-term alterations in temperature and weather patterns across the globe. It is primarily caused by the release of greenhouse gases, such as carbon dioxide and methane, into the atmosphere. These gases trap heat from the sun, leading to a gradual rise in global temperatures known as global warming.
One of the main contributors to climate change is the burning of fossil fuels, which releases large amounts of carbon dioxide into the atmosphere. The combustion of coal, oil, and natural gas for electricity generation, transportation, and industrial processes accounts for a significant portion of greenhouse gas emissions. Deforestation also plays a role in climate change, as trees absorb carbon dioxide and release oxygen. When forests are cleared, the stored carbon is released back into the atmosphere.
The consequences of climate change are wide-ranging and pose significant challenges to both human and natural systems. Rising temperatures contribute to the melting of polar ice caps and glaciers, leading to a rise in sea levels. This, in turn, increases the risk of coastal flooding and erosion, threatening coastal communities and ecosystems. Changes in precipitation patterns result in more frequent and intense droughts, heatwaves, and storms, impacting agriculture, water resources, and public health. Furthermore, shifts in climate conditions can disrupt ecosystems, causing species extinction and affecting biodiversity.
Addressing climate change requires a multi-faceted approach that involves mitigation and adaptation strategies. Mitigation involves efforts to reduce greenhouse gas emissions and minimize the impact of human activities on the climate. This can be achieved through the transition to renewable energy sources, energy efficiency measures, and sustainable land use practices. Adaptation focuses on building resilience to the impacts of climate change, such as developing infrastructure to withstand extreme weather events and implementing strategies to protect vulnerable populations.
The urgency of addressing climate change has led to global initiatives and agreements, such as the Paris Agreement, which aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels. However, the successful implementation of climate change mitigation and adaptation measures requires collective action at the international, national, and individual levels.
Q. What is the primary purpose of reforestation in addressing climate change?
  • a)
    To reduce greenhouse gas emissions
  • b)
    To transition to renewable energy sources
  • c)
    To absorb carbon dioxide and release oxygen
  • d)
    To adapt to changes in precipitation patterns

Paleontologists have been intrigued by the fossil remains of the pterosaurs, the first flying vertebrates, for over two centuries. The challenges of powered flight and the true nature of these creatures, whether they were reptiles or birds, have been subjects of debate among scientists. However, it is generally accepted that pterosaurs were reptiles based on their skull, pelvis, and hind feet anatomy. Their wings, characterized by a greatly elongated fourth finger supporting a wing-like membrane, suggest they did not evolve into birds. Pterosaurs had a combination of bird-like and bat-like features in their overall structure and proportions, which is not surprising considering the aerodynamic constraints of flight in vertebrates.
Both pterosaurs and birds have hollow bones, reducing weight, but bird bones are reinforced internally. It is likely that pterosaurs had a coat of hair to insulate against heat loss and streamline their bodies during flight. The recent discovery of a pterosaur specimen covered in hair-like fossil material supports this hypothesis. The question of how pterosaurs became airborne has led to various suggestions, including launching themselves from cliffs, dropping from trees, or using updrafts from high waves. Each hypothesis has its limitations, such as the mismatch between pterosaur feet and bat feet for cliff launching and the potential difficulty of large pterosaurs landing in trees without damaging their wings.
Q. The authors views the idea that the pterosaurs became airborne by rising into light windscreated by waves as
  • a)
    revolutionary
  • b)
    unlikely
  • c)
    unassailable
  • d)
    probable
  • e)
    outdated
Correct answer is option 'B'. Can you explain this answer?

Ayesha Joshi answered
The passage mentions that the hypothesis of using light winds from waves to become airborne seems unlikely due to potential difficulties controlling flight in strong winds.

The passage mentions that income transfers in the country have primarily focused on the elderly, disabled, and dependent, neglecting the needs of the working poor. Therefore, the employed poor often do not benefit from the mitigating effect of social programs involving income transfers.

Directions: Passage For Question 10 to 15
The passage discusses the behavior and characteristics of the indigo bunting, a strongly territorial bird. The main mechanism for securing, defining, and defending a suitable breeding area in this species is through song. Only the strongest males can retain a good territory when population density is high, while the weakest males either do not breed or are forced onto poor or marginal territories. The male indigo bunting sings in his territory during the breeding season, producing melodic and rhythmic songs with distinct figures. These figures are reproduced consistently, with a limited variety despite the large frequency range and rapid changes in sound. The study found that male indigo buntings are capable of singing many more types of figures than they usually do, suggesting that they learn and copy figures from other buntings they hear. The ability to distinguish the songs of their own species from other species is important, as male indigo buntings did not respond to recordings of other bird species. Additionally, the passage explores the role of song figures in interspecies recognition and the importance of specific frequency ranges, duration limits, and intervals between figures. The passage concludes that there is a balance between song stability for species recognition and song variation for individual recognition.
Q. It can be inferred from the passage that the existence of only a limited number of indigobunting figures servers primarily to
  • a)
    ensure species survival by increasing competition among the fittest males for the females
  • b)
    increase population density by eliminating ambiguity in the figures to which the females mustrespond
  • c)
    maintain the integrity of the species by restricting the degree of figure variation and change
  • d)
    enhance species recognition by decreasing the number of figure patterns to which the birdmust respond
  • e)
    avoid confusion between species by clearly demarcating the figure patterns of each specials
Correct answer is option 'D'. Can you explain this answer?

Ayesha Joshi answered
The passage states that a specific configuration is not essential for interspecies recognition, but the figures must conform to a particular frequency range, duration limits, and spacing intervals. Having a limited number of figure patterns helps enhance species recognition by reducing the potential ambiguity for the bird in identifying and responding to the figures.

Directions: Passage For Question 10 to 15
Woodrow Wilson referred to the liberal concept of the economic market and expressed the belief that the free enterprise system is the most efficient economic system. According to Wilson, maximum freedom leads to maximum productivity, and the measure of our stability lies in our openness. This fascination with the ideal of maximum freedom has caused Americans to reject the traditional categories of settled possessiveness versus unsettling deprivation, the desire to retain versus the desire to seize, and the defense or attack of the status quo. In the United States, there is no status quo ante; our only "station" is the constant turning of a stationary wheel, spinning faster and faster. Our system is not based on property but on opportunity, which means it is rooted in mobility rather than stability. The more things change, the more rapidly the wheel turns, the more steadfast we become.
The conventional understanding of class politics consists of the Haves, who seek stability to preserve their possessions, and the Have-Nots, who desire a touch of instability and change to scramble for what they lack. However, Americans envision a condition where speculators, self-made individuals, and runners constantly seize the new opportunities provided by our land. These economic leaders, or front-runners, are seen as agents of change. On the other hand, those who are left behind, the nonstarters, seek stability and a strong referee to secure their position in the race, a regulating force to calm manic speculation, and an authority that can reset things from staggered starting lines. "Reform" in America has been ineffective because it can only imagine change through the extension of the metaphor of the race, including wider inclusion of competitors and giving a "piece of the action" to the disenfranchised. There is no attempt to call off the race, as our only stability comes from constant change.
According to the passage, the American legends do not honor the quiet work that fosters social interdependence and stability. There is no heroism attributed to office clerks or a stable industrial workforce, the people who actually make the system function. Being an employee is not a source of pride (Wilson called for a return to the time when everyone was an employer). Social workers are not praised or boasted about; they are viewed as a necessity. The empty boasts from the past make us ashamed of our present achievements, pushing us to try to forget or deny them, to distance ourselves. In this wonderland race we all must run, there is no honor, as everyone strives to win but no one ultimately succeeds because there is no end.
Q. It can be inferred from the passage that Woodrow Wilson's ideas about the economic market
  • a)
    encouraged those who "make the system work"
  • b)
    perpetuated traditional legends about America
  • c)
    revealed the prejudices of a man born wealthy
  • d)
    foreshadowed the stock market crash of 1929
  • e)
    began a tradition of presidential proclamations on economics
Correct answer is option 'B'. Can you explain this answer?

Ayesha Joshi answered
The passage implies that Woodrow Wilson's ideas about the economic market perpetuated traditional legends about America rather than promoting the interests of those who "make the system work."

Directions: Passage For Question 1 to 9
The majority of economists in the United States are strongly influenced by the ideology of the free market. Anything that does not conform to the principles of the free market is often viewed as negative or abnormal. The idea of sellers or any other entity determining prices, instead of the collective decisions of consumers, is seen as harmful. However, price-fixing, which is the determination of prices by sellers, is actually a normal occurrence in industrialized societies. In such societies, the industrial system itself leads to price-fixing as a natural consequence of its development. Large firms in these societies compete for the same group of consumers, and while they consider their own interests, they also take into account the common needs they share with other large firms. As a result, significant price cutting is avoided to maintain a stable demand for products. Many economists fail to recognize price-fixing because they expect it to be the result of explicit agreements among large firms, but it often occurs without such explicit agreements. Additionally, economists who argue in favor of free-market principles as the most efficient method of establishing prices have not considered the experiences of non-socialist countries other than the United States. These countries commonly engage in intentional price-fixing through cartels and agreements among industry members. If the free market were significantly more efficient than price-fixing, these countries would have suffered economically, but there is no evidence to support this. Even in socialist systems, controlled prices are used in their industries. In the early 1970s, the Soviet Union began allowing some flexibility in price adjustments for firms and industries, which has been hailed by U.S. economists as a return to the free market. However, Soviet firms are still not subject to prices established by a free market, as they have little influence over them.
Q. According to the passage, most economists in the United States are captivated by the spell of which concept?
  • a)
    Socialism
  • b)
    Price-fixing
  • c)
    Free market
  • d)
    Industrial planning
  • e)
    Cartels
Correct answer is option 'C'. Can you explain this answer?

Climate change is one of the most pressing global issues of our time. It refers to long-term shifts in weather patterns and average temperatures on Earth, largely caused by human activities such as the burning of fossil fuels and deforestation. The consequences of climate change are far-reaching and impact various aspects of our planet, including ecosystems, economies, and human health.
One of the primary concerns related to climate change is the rise in global temperatures. The increase in greenhouse gases, such as carbon dioxide, in the Earth's atmosphere traps heat and leads to a phenomenon known as the greenhouse effect. This warming effect results in rising sea levels, melting polar ice caps, and more frequent extreme weather events like hurricanes, droughts, and heatwaves.
Moreover, climate change poses significant risks to biodiversity and ecosystems. As temperatures rise, many species struggle to adapt to new conditions, leading to shifts in habitats and potential species extinctions. Coral reefs, for example, are particularly vulnerable to the warming and acidification of oceans, which can cause mass coral bleaching and disrupt entire marine ecosystems.
The economic implications of climate change are also substantial. Agricultural productivity is threatened by changing rainfall patterns and increased occurrences of pests and diseases. Extreme weather events can damage infrastructure, disrupt supply chains, and displace communities, resulting in significant financial costs. Furthermore, the transition to a low-carbon economy and the development of renewable energy sources are vital for mitigating climate change and reducing dependency on finite fossil fuel resources.
Addressing climate change requires a global effort and the implementation of sustainable practices. This includes reducing greenhouse gas emissions, promoting renewable energy sources, conserving natural resources, and adopting climate-resilient strategies. Additionally, raising awareness and educating individuals about the importance of climate action can lead to behavioral changes and collective action.
Q. What is the greenhouse effect?
  • a)
    The cooling of Earth's atmosphere due to greenhouse gases
  • b)
    The trapping of heat by greenhouse gases in the Earth's atmosphere
  • c)
    The depletion of ozone layer leading to increased solar radiation
  • d)
    The absorption of greenhouse gases by oceans, reducing their impact
  • e)
    The removal of carbon dioxide from the atmosphere by plants
Correct answer is option 'B'. Can you explain this answer?

Ayesha Joshi answered
The passage explains that the greenhouse effect is the trapping of heat by greenhouse gases in the Earth's atmosphere, making option B the correct choice.

Directions: Passage For Question 1 to 10
In recent years, there has been a growing debate among scientists regarding the impact of climate change on global ecosystems. While the majority of scientists agree that human activities are contributing to the rise in global temperatures, there is still a minority of researchers who dispute this consensus. These skeptics argue that natural climate variability and other factors may be responsible for the observed changes, and they question the accuracy of climate models used to predict future trends.
One of the key arguments put forth by climate change skeptics is the historical variability of Earth's climate. They point to periods in the past when the planet experienced significant climate fluctuations without any human influence. According to these skeptics, this historical variability suggests that current changes in climate may also be part of a natural cycle and not solely caused by human actions.
Additionally, skeptics often criticize the use of climate models to make predictions about future climate scenarios. They argue that these models are based on simplified assumptions and may not accurately capture the complexity of Earth's climate system. Furthermore, they highlight instances where past predictions made by climate models have not aligned with actual observations, casting doubt on the reliability of future projections.
However, the scientific consensus on climate change remains strong. The Intergovernmental Panel on Climate Change (IPCC), a body of leading scientists from around the world, has consistently emphasized the role of human activities, particularly the burning of fossil fuels, in driving climate change. The IPCC's reports provide comprehensive assessments of the current state of knowledge and highlight the overwhelming evidence supporting human-induced climate change.
Critics argue that the consensus among scientists is influenced by political and ideological factors rather than scientific evidence. They suggest that scientists who support the consensus position receive more funding and recognition, while dissenting voices are marginalized. However, this claim is not substantiated by empirical evidence and overlooks the rigorous peer-review process that scientific research undergoes.
In conclusion, while there may be a minority of skeptics challenging the consensus on climate change, the weight of scientific evidence overwhelmingly supports the role of human activities in driving global warming. It is crucial to heed the warnings of scientists and take collective action to mitigate the impact of climate change on our planet.
Q. Which of the following statements is NOT supported by the passage?
  • a)
    Climate change skeptics argue that human activities are the primary cause of global warming.
  • b)
    The majority of scientists agree that human activities contribute to the rise in global temperatures.

The extent of suffering caused by labor market problems is a critical but contentious social policy question. Social statistics often exaggerate the level of hardship experienced. Unemployment today does not have the same severe consequences as in the 1930s when most jobless individuals were primary breadwinners, income levels were closer to subsistence, and social programs were lacking. Factors such as increased affluence, more dual-earner families, and improved social welfare have mitigated the impact of joblessness. Similarly, earnings and income data overstate hardship. Many individuals with low hourly earnings, including those near the minimum wage, come from relatively affluent families with multiple earners. Poverty statistics also do not accurately reflect labor market issues, as they mainly include the elderly, disabled, or individuals with family responsibilities who are not part of the labor force. However, social statistics also underestimate the hardship related to the labor market. Unemployment counts exclude fully employed workers with low wages, who still live in poverty. Low wages and repeated or prolonged unemployment often combine to undermine self-support. Additionally, the number of people experiencing joblessness at some point during the year is higher than the average monthly unemployment, with part-time workers and individuals wanting a job but not in the labor force. Furthermore, income transfers primarily focus on the elderly and dependent, neglecting the needs of the working poor. The contradictory evidence makes it uncertain whether the number of individuals suffering due to labor market problems is in the hundreds of thousands or tens of millions, and whether high levels of joblessness require job creation and economic stimulus. The existing poverty, employment, and earnings statistics are inadequate for measuring the consequences of labor market problems.
Q. The author's purpose in citing those who are repeatedly unemployed during a twelve-monthperiod is most probably to show that
  • a)
    there are several factors that cause the payment of low wags to some members of the laborforce
  • b)
    unemployment statistics can underestimate the hardship resulting from joblessness
  • c)
    recurrent inadequacies in the labor market can exist and can cause hardships for individualworkers.
  • d)
    A majority of those who are jobless at any one time do not suffer severe hardship
  • e)
    There are fewer individuals who are without jobs at some time during a year than would beexpected on the basis of monthly unemployment figures
Correct answer is option 'B'. Can you explain this answer?

Ayesha Joshi answered
The passage mentions that the number of individuals experiencing joblessness at some point during the year is higher than the average monthly unemployment. By citing those who are repeatedly unemployed over a twelve-month period, the author aims to demonstrate that unemployment statistics can underestimate the hardship caused by joblessness.

Directions: Passage For Question 1 to 9
Certain examples of poetic justice found in medieval and Elizabethan literature have inspired twentieth-century scholars to seek out additional instances. However, these scholars have merely imposed a moral framework on victimized characters, justifying the injustices inflicted upon them in one way or another. They deny the innocence of the sufferers in a tragedy and hold them responsible for their tragic fates. Any wrongdoing on the part of a character is enough to subject them to critical scrutiny. For instance, there are lengthy essays analyzing the wrongdoings of Webster's Duchess of Malfi, who defied her brothers, and the behavior of Shakespeare's Desdemona, who disobeyed her father.
Yet it is worth remembering that Renaissance writer Matteo Bandello strongly objected to the unjustly severe punishments imposed on women for acts of disobedience, while men could commit similar acts with virtual impunity. Shakespeare, Chaucer, and Webster often enlist their readers to sympathize with their tragic heroines by portraying cruel injustices that evoke a sense of protest. Chaucer, in the Clerk's Tale, presents Griselda as a meek and gentle victim who does not criticize or rebel against her oppressive husband, Walter. This portrayal incites readers to support Griselda against Walter's tyranny. Thus, attempts to justify Walter's persecutions with historical and theological arguments contradict the intended effect on readers' sympathies in Chaucer's fable. Similarly, asserting that Webster's Duchess deserved torture and death because she chose to marry the man she loved and bear their children aligns with her tyrannical brothers and confuses the concept of poetic justice, which readers should endorse, with social injustices that Webster clearly condemns. In fact, Webster depicts his heroine as a courageous leader in resistance against tyranny, inspiring the audience to join her in opposing the cruelty and hypocritical morality of her brothers. In their own distinct ways, both Chaucer and Webster challenge injustice, advocate for the victims, and denounce the oppressors. The readers serve as a court of appeal for them, remaining free to render judgments based on evidence and common humanity. As the esteemed eighteenth-century scholar Samuel Johnson paraphrased, it is through the common sense and compassion of readers, uncorrupted by the characters and situations in medieval and Elizabethan literature, that these works, like any other literature, can be best evaluated.
Q. As described in the passage, the process by which some twentieth-century scholars havereached their conclusions about the blameworthiness of victims in medieval and Elizabethanliterary works is mot similar to which of the following?
  • a)
    Derivation of logically sound conclusions from well-founded premises
  • b)
    Accurate observation of data, inaccurate calculation of statistics, and drawing of incorrectconclusions form the faulty statistics
  • c)
    Establishment of a theory, application of the theory to ill-fittings data, and drawing ofunwarranted conclusions from the data
  • d)
    Development of two schools of thought about a factual situation, debate between the twoschools, and rendering of a balanced judgment by an objective observer
  • e)
    Consideration of a factual situation by a group, discussion of various possible explanatoryhypotheses and agreement by consensus on the most plausible explanation
Correct answer is option 'C'. Can you explain this answer?

Ayesha Joshi answered
The passage describes how some twentieth-century scholars have forced victimized characters into a moral framework by justifying the injustices inflicted upon them. This process can be compared to the establishment of a theory, applying the theory to data that may not fit well, and drawing unwarranted conclusions based on that data.
