Given:
  • The function [z]
  • [z2] = 2
To find: Can [z] be {2, 1, -2}?
Approach:
  1. To find which values of [z] are possible and which are not, we need to first know the range of possible values of z. Once we know what z can be, we’ll be able to find what [z] can be.
  2. We’ll get an idea of the possible values of z from the fact that [z2] = 2

The prevailing theory of our Moon's origin is that it was created by a giant impact between a large planet-like object and the proto-Earth very early in the evolution of our solar system. The energy of this impact was sufficiently high that the Moon formed from melted material that began with a deep liquid magma ocean. As the Moon cooled, this magma ocean solidified into different mineral components, the lightest of which floated upwards to form the oldest crust. Although samples of this presumed ancient crust were brought back to Earth by the Apollo 16 mission in 1972, it was not until recently that scientists could successfully date them. Recent analysis of one of the samples, a rock called ferroan anorthosite or FAN, which is believed to be the oldest of the Moon's crustal rocks, has given scientists new insights into the formation of the Moon, suggesting that the Moon may be much younger than currently believed.
The sample that had been carefully stored at NASA’s Johnson Space Center had to be extensively pre-cleaned to remove terrestrial contamination. Once the sample was contamination free, the researchers were able to study it. The team analyzed the isotopes of the elements lead and neodymium to place the age of the sample at 4.36 billion years. This figure is significantly younger than earlier estimates of the Moon's age that range to nearly as old as the age of the solar system itself at 4.567 billion years. The new, younger age obtained for the oldest lunar crust is similar to ages obtained for the oldest terrestrial minerals -- zircons from Western Australia -- suggesting that the oldest crust on both Earth and the Moon formed at approximately the same time.
This study is the first in which a single sample of FAN yielded consistent ages from multiple isotope dating techniques. This result strongly suggests that these ages pinpoint the time at which this sample crystallized. The extraordinarily young age of this lunar sample either means that the Moon solidified significantly later than previous estimates -- and therefore the moon itself is much younger than previously believed -- or that this sample does not represent a crystallization product of the original magma ocean. Either scenario requires major revision to existing models for the formation of the Moon.

To maximize profits, an employer should control his or her environment in a factory, shop, or office and make sure that examples of energy and efficiency are numerous enough to catch employee attention and establish an atmosphere of industry. In the workplace, there are instances in which it would be in the mutual interest of the employer and the employees to increase the speed of work, but conditions may limit or forbid the use of pace-setters. In construction work and in some of the industries, where there are minute subdivisions of operations and continuity of processes, this method of increasing efficiency is very commonly applied with the use of time cards and software. In many factories, however, such an effort to “speed up” production might stir resentment, even among the workers paid at a fixed rate for each unit produced or action performed, and have an effect exactly opposite to that desired. The alternative, of course, is for the employer to secure unconscious pace setting by providing incentives for the naturally ambitious men and women in the way of a premium or bonus system or other reward for above-average efficiency.
Accordingly, to take advantage of the benefits of conscious or voluntary imitation, workers must be provided with examples that appeal to them as admirable and inspire the wish to emulate them. A common application of this principle is seen in the choice of department heads, foremen, and other bosses. Invariably these people win promotion by industry, skill, and efficiency greater than that displayed by their direct peers, or by mastery of their skills that enables them to show their less efficient peers how any and all operations should be conducted. This focusing of attention upon individuals worthy of imitation has been carried much farther by various companies. Some create weekly or monthly papers published primarily for circulation within the organization to record every incident reflecting unusual skill, initiative, or personal power in an individual member of the organization. A big order closed, a difficult contract secured, a complex or delicate operation performed in less than the usual time, a new personal record in production, the invention of an unproved method or machine—whatever the achievement, it is described and glorified, its perpetrator praised and held up for emulation. This, indeed, is one of the methods by which the larger sales organizations have obtained remarkable results.

For an overlapping set problem we can use a double-set matrix to organize our information and solve.  The boldfaced values were given in the question. The non-boldfaced values were derived using the fact that in a double-set matrix, the sum of the first two rows equals the third and the sum of the first two columns equals the third.  The variable p was used for the total number of pink roses, so that the total number of pink and red roses could be solved using the additional information given in the question.

The question states that the percentage of red roses that are short-stemmed is equal to the percentage of pink roses that are short stemmed, so we can set up the following proportion:

This means that there are a total of 75 pink roses and 25 red roses.   Now we can fill out the rest of the double-set matrix:

 
Now we can answer the question.  20 of the 80 long-stemmed roses are red, or 20/80 = 25%.
The correct answer is B.

In the year 1885, the Eiffel firm, which was named after the French engineer and architect Gustave Eiffel and which had extensive experience in structural engineering, undertook a series of investigations of tall metallic piers based upon its recent experiences with several railway viaducts and bridges. The most spectacular of these was the famous Garabit Viaduct, which carries a railroad some 400 feet above the valley of the Truyere in southern France. The design of this structure was the inspiration for the design of a 395-foot pier, which, although never incorporated into a bridge, is said to have been the direct basis for the Eiffel Tower. Preliminary studies for a 300-meter tower were made with the intention of showcasing it in the 1889 fair called Exposition Universelle. With an assurance born of positive knowledge, Eiffel in June of 1886 approached the Exposition commissioners with the project. There can be no doubt that only the singular respect with which Eiffel was regarded not only by his profession but by the entire nation motivated the Commission to approve a plan which, in the hands of a figure of less stature, would have been considered grossly impractical.
Between this time and the commencement of the Tower’s construction at the end of January 1887, there arose one of the most persistently annoying of the numerous difficulties, both structural and social, which confronted Eiffel as the project advanced. In the wake of the initial enthusiasm—on the part of the fair’s Commission that was inspired by the desire to create a monument to highlight French technological achievement, and on the part of the majority of French people by the stirring of their imagination at the magnitude of the structure—there grew a rising movement of disfavor. At the center of this movement was, not surprisingly, the intelligentsia, but objections were made by prominent French people from all walks of life.
The most interesting point to be noted in a retrospection of this often violent opposition is that, although every aspect of the Tower was attacked, there was remarkably little criticism of its structural feasibility, either by the engineering profession or, as seems traditionally to be the case with bold and unprecedented undertakings, by large numbers of the technically uninformed population. True, there was an undercurrent of what might be characterized as unease by many property owners in the structure’s shadow, but the most obstinate element of resistance was that which deplored the Tower as a mechanistic intrusion upon the architectural and natural beauties of Paris. This resistance voiced its fury in a flood of special newspaper editions, petitions, and manifestos signed by such lights of the fine and literary arts as De Maupassant, Gounod, Dumas fils, and others.

In general, psychology is the study of human thought and consciousness and includes everything from the biological way in which cognitive processes occur to why people behave in certain ways. Sociology, on the other hand, is the study of society and how people interact with each other in different ways. The major differences between psychology and sociology typically concern the focal points of each field and how those foci are studied. In psychology, for example, the focus of research typically involves understanding the human cognitive process and how the brain functions in general. In sociology, however, there is a great deal of importance placed on the role that society has in the formation of human thought and action. Even though sociology does include how people think with relation to each other, human thought is not necessarily the sole focus. Also, since it studies the interactions between people, sociology can lay much more importance on actions than psychology does, stressing the importance of human behavior over cognitive responses or processes.
 
There are some ways in which both psychology and sociology are similar, however, such as the ways in which the fields cross into each other. Social psychology, for example, is quite similar to sociology in that it focuses on how people interact and how society affects the thoughts and mental activities of individual people. Explorations within sociology on how social interactions can be based on various psychological principles can also connect the two disciplines. Ultimately, someone interested in different facets of psychology and sociology is likely to study both fields and find that there are numerous ways in which they can relate and enhance each other.

SANCHITA SINHA asked   •  4 hours ago

Characterized by change of ideals, Sanskritization traditionally denoted the process by which castes placed lower in the caste hierarchy sought upward mobility by emulating the rituals and practices of the upper castes. It became an inevitable feature of those castes that experienced a vast gap between their ritual and politico-economic positions. Such castes enjoyed a high level of political and economic power. Accordingly, economic elevation was not a sought- after goal through Sanskritization. Infact, sometimes a group could start by acquiring political power, which led to economic betterment and Sanskritization.
Although there is no unanimity on whether it has been a major process of cultural change in Indian history, it has occurred almost in every part of the Indian sub-continent. However, the nature of the process is by no means uniform as the cultural norms or customs being imitated may vary from Sanskrit or Hindu traditional forms to tribal and even the Islamic patterns. Also, with the passage of time, the boundaries of the definition have blurred and today Sanskritization is no longer limited to the changes in the customs, rituals and ideology and way of life of a caste placed lower in the caste hierarchy; it has now begun to stand for cross imitation of customs and way of life among different social groups. In essence, Sanskritization is only an illustration of the operation of the ‘reference group’ process. A reference group is a group that is used as a standard to evaluate one’s rituals, attitudes, customs etc. As long as the caste has prestige in the social groups, it serves as a model. Accordingly, a ruling group or caste will also serve as a model if it commands prestige in the society.

A firm’s default risk, the measurement of the chances of the event in which the company will be unable to make the required payments on its debt obligations, reflects not only the likelihood that the firm will have bad luck but also the risk that the firm’s managerial decisions will lead the firm to default. Such management risk occurs because the impact of management on the firm’s value is uncertain, and this uncertainty affects the market’s perception of a firm’s risk.  Uncertainty about management is likely to be the highest when there is a new management team and should decrease over time as management’s ability becomes known more precisely. In particular, when the new CEO is not considered an “heir apparent” prior to getting the position, or when he comes from outside of the company, or when the new CEO is younger, the market is expected to perceive relatively high uncertainty about the CEO’s ability or future actions. Accordingly, it comes as no surprise that the CDS spread, a measure of a firm’s expected default risk, is about 35 basis points higher when a new CEO takes office than three years into his tenure. The CEO, however, is not the only member of the management team who is relevant for decision making in the firm. Chief Financial Officers (CFOs) have a large role in financial decision-making, so uncertainty about new CFOs could also affect the firm’s default risk and cost of borrowing.
Now, a central feature of financial markets is that the interest rate a firm pays on debt increases with an increase in the market’s perception of the firm’s risk. This risk occurs because of factors that affect the value of the firm’s underlying assets and because of uncertainty about how these assets will be managed. The literature on debt pricing typically does not distinguish between these types of underlying risks. However, all risks, including those generated by uncertainty about management, affect the likelihood of default. Consequently, a rational market should incorporate managerial-generated uncertainty into its assessment of a firm’s risk when pricing its securities. Also since uncertainty about management affects firms’ costs of borrowing and consequently their financial policies, the value of maintaining transparency in managerial policies and communicating them to the marketplace should be realised.

Steps 1 & 2: Understand Question and Draw Inferences
In this question, both CP and SP are expressed in terms of the marked price.
 
Let the marked price of the item be M
The cost price at which the merchant had bought the item was a % less than the marked price
=> CP = M – a % of M
=> CP = (1 - a/100) M

Logical arguments are usually classified as either deductive or inductive, depending on the process used to arrive at them. In the process of deduction, you begin with some statements, called premises, which are assumed to be true, and you then determine what else would have to be true if the premises are true. For example, in mathematics you can begin with some axioms and then determine what you can prove to be true given those axioms are true. With deduction you can provide absolute proof of your conclusions, since your premises are considered correct. The premises themselves, however, remain unproven and unprovable; they must be accepted on face value, or by faith, or for the purpose of exploration.
On the other hand, in the process of induction, you begin with some data, and then determine what general conclusion(s) can logically be derived from that data. In other words, you determine what theory or theories could explain the data. For example, you note that the probability of becoming schizophrenic is greatly increased if at least one parent is schizophrenic, and from that you conclude that schizophrenia may be inherited. That is certainly a reasonable hypothesis given the data. Note, however, that induction does not prove that the theory is correct. There are often alternative theories that are also supported by the data. For example, the behavior of the schizophrenic parent may cause the child to be schizophrenic, not the genes. What is important in induction is that the theory does indeed offer a logical explanation of the data. To conclude that the parents have no effect on the schizophrenia of the children is not supportable given the data, and would not be a logical conclusion.
Both deduction and induction by themselves are inadequate for a scientific approach. While deduction gives absolute proof, it never makes contact with the real world; there is no place for observation or experimentation - no way to test the validity of the premises. And, while induction is driven by observation, it never approaches actual proof of a theory. Accordingly, a synthesis of these two logical approaches is required for an actual scientific method.
Which one of the following statements can be inferred about the induction process of arriving at a logical argument?

A team of researchers has been able to successfully study the highly complex molecular structure of mitoribosomes, which are the ribosomes of mitochondria. Ribosomes are found in the cells of all living organisms, and they serve as a primary location for biological protein synthesis, but certain organisms such as fungi, plants, animals, and humans contain much more complex ribosomes than bacteria do. In organisms with complex cells, ribosomes can also be divided into two types: those in the cytosol -- which comprises the majority of the cell -- and those found in the mitochondria or "power houses" of cells. Mitochondria are found only in eukaryotes. Every ribosome consists of two subunits. The smaller subunit uses transfer ribonucleic acids to decode the genetic code, which is stored in the DNA, it receives in the form of messenger ribonucleic acids, while the larger subunit joins the amino acids delivered by the transfer ribonucleic acids together like a string of pearls. 
Since they are found only in small amounts and are difficult to isolate, mitochondrial ribosomes or mitoribosomes are particularly difficult to study.  But because of the recent technical advances in cryo-electron microscopy and the development of direct electron detection cameras that can correct for specimen motion during the exposure, it recently became possible to capture images of biomolecules at a resolution high enough to capture the details, especially those of the peptidyl transferase centre (PTC).
This research is of special importance to producing the right kind of antibiotics for humans. PTC is where the amino acid building blocks are combined, leading to protein synthesis. As per the researchers, this process of synthesizing proteins is medically relevant as the tunnel through which the proteins pass, after being synthesized, is a target for specific antibiotics. The antibiotic blocks the tunnel, preventing the proteins that have just been synthesized from leaving the tunnel. However, for an antibiotic to be used in humans, it must not attack human ribosomes and should inhibit protein synthesis only in the ribosomes of bacteria.  The problem arises since mitochondrial ribosomes resemble those of bacteria, which is why certain antibiotics also interfere with mitoribosomes, possibly leading to serious side effects. The findings of the research will make it possible in the future to design antibiotics that inhibit only bacterial and not mitochondrial ribosomes, the one basic requirement for using them in clinical applications.

Individual studies and experiments the world over have shown that a strong correlation exists between music and mood --- listening to a particular kind of music impacts the mood of the listener. In fact studies have also shown that, in everyday life, music is primarily used for mood and emotion regulation. Indeed, one of the reasons music is able to transcend the barriers of language and garner universal appeal is the emotional response it evokes in its listeners. However, not all people respond similarly to the same kind of music.
A new study shows that listening to the same piece of sad music can actually make some people happy while others sad. Clearly, the difference in the response generated is due to the difference or the lack of the same in the perceived and the induced emotions experienced by the participants. Perceived emotion is defined as the act of sensing the emotional content of the stimuli whereas induced emotion is the emotion felt by the receiver after being subjected to the stimuli.
In the study, the participants with a higher level of exposure to and knowledge of music were the ones who reported being happy after listening to the music, while others reported as being sad. These participants rated the piece of sad music as highly unpleasant on the scale of perceived emotions; however, their induced emotion score was really low for the level of unpleasantness experienced by them and hence did not match with their perceived emotions score. For this reason, these participants felt that they could enjoy the piece of music without feeling sad and hence reported their emotional state as closer to being happy.
However, the findings of the study do not necessarily suggest that the perceived emotion score by the not so musically literate was low. It could just mean that either their perceived and induced emotion scores coincided or that the difference between the two was insignificant.

Although postcolonial theory does not propose a simple causal relation between literature and political action, it nonetheless views literature as an enabler of nationalism and in turn political action: literature imagines the community of the nation, giving it a virtually mythical status. The power of the national imaginary to inspire political action is never in doubt, but the precise mechanisms by which this happens or whether indeed any kind of direct causality is involved remains unclear. It may very well be that literature and political action are reciprocating parts of a complex process for which such questions are peripheral.
 
An example of such reciprocation is an early play by Yeats, The King’s Threshold (1904), in which an ancient Irish poet goes on hunger strike to protest against his king.  This play might be thought to have engendered the hunger strikes Irish republicans resorted to, first during the struggle with Britain from 1916 to 1920, then in the civil war that followed as they fought against the Free State government forces, and finally in 1981 as they resisted continuing British rule in Northern Ireland. Similarly in reciprocation, when the Republican mayor of Cork, Terence MacSwiney, died in hunger strike in 1920, Yeats revised his play, and gave it a revised conclusion – a tragic ending, attributing the tragic ending as a great improvement & much more representative of the then political climate.

The generally agreed upon definition of hallucinations is that they are actually perceptions in the absence of an external stimulus of the relevant sensory organ. These perceptions are accompanied by a persuasive sense of their reality. Hallucinations are not to be confused with illusions, which are misinterpretations of actual external stimuli. In other words, in the case of a hallucination, for a person hallucinating a sound for instance, the sound actually exists, but in reality it exists nowhere but in the person’s mind; however, in the case of an illusion the stimulus that caused the illusion does exist in the real world. Although hallucinations are a key diagnostic feature of schizophrenia, a mental disorder that distorts the way a person thinks, acts, expresses emotions, perceives reality, and relates to others, they can occur in individuals devoid of any physical or mental disorder.
In order to understand why people hallucinate, some researchers have been studying people suffering from what is called the phantom limb syndrome, a condition in which people who have undergone amputation feel as though the missing body part were still very much present and attached to the body; for instance, it is not uncommon for a person who has lost a leg to unknowingly try to stand and walk without any external support after their surgery. One of the two main hypotheses behind the phantom limb syndrome offers an explanation that is possibly applicable to why people hallucinate in certain circumstances. As per this theory, the brain is programmed for a body where every body part is intact and in the appropriate place. Accordingly, when some signals go missing, because of the missing body part, the brain compensates for the lack of sensory input by triggering spontaneous nerve cell activity. Although this theory has limited applicability for understanding why patients such as those of schizophrenia hallucinate in conditions not deemed out of the ordinary, it is a step forward in understanding why people experience visual or auditory hallucinations when they are placed in solitary confinements; after all the different areas of the brain that were used to receiving signals through the senses start to stimulate themselves in to action.

In the year 1885, the Eiffel firm, which was named after the French engineer and architect Gustave Eiffel and which had extensive experience in structural engineering, undertook a series of investigations of tall metallic piers based upon its recent experiences with several railway viaducts and bridges. The most spectacular of these was the famous Garabit Viaduct, which carries a railroad some 400 feet above the valley of the Truyere in southern France. The design of this structure was the inspiration for the design of a 395-foot pier, which, although never incorporated into a bridge, is said to have been the direct basis for the Eiffel Tower. Preliminary studies for a 300-meter tower were made with the intention of showcasing it in the 1889 fair called Exposition Universelle. With an assurance born of positive knowledge, Eiffel in June of 1886 approached the Exposition commissioners with the project. There can be no doubt that only the singular respect with which Eiffel was regarded not only by his profession but by the entire nation motivated the Commission to approve a plan which, in the hands of a figure of less stature, would have been considered grossly impractical.
Between this time and the commencement of the Tower’s construction at the end of January 1887, there arose one of the most persistently annoying of the numerous difficulties, both structural and social, which confronted Eiffel as the project advanced. In the wake of the initial enthusiasm—on the part of the fair’s Commission that was inspired by the desire to create a monument to highlight French technological achievement, and on the part of the majority of French people by the stirring of their imagination at the magnitude of the structure—there grew a rising movement of disfavor. At the center of this movement was, not surprisingly, the intelligentsia, but objections were made by prominent French people from all walks of life.
The most interesting point to be noted in a retrospection of this often violent opposition is that, although every aspect of the Tower was attacked, there was remarkably little criticism of its structural feasibility, either by the engineering profession or, as seems traditionally to be the case with bold and unprecedented undertakings, by large numbers of the technically uninformed population. True, there was an undercurrent of what might be characterized as unease by many property owners in the structure’s shadow, but the most obstinate element of resistance was that which deplored the Tower as a mechanistic intrusion upon the architectural and natural beauties of Paris. This resistance voiced its fury in a flood of special newspaper editions, petitions, and manifestos signed by such lights of the fine and literary arts as De Maupassant, Gounod, Dumas fils, and others.
Based on the discussion of public opinion regarding the Eiffel Tower's construction it can be inferred that

A new security software authenticates a person by scanning the person’s hand and matching the information obtained from the same with the information stored in the system. However, recent laboratory tests have shown that the software recognized and authenticated people whose information in the system was stored before they recently started suffering from chemotherapy-induced acral erythema, a syndrome that is associated with pain and peeling on the palms and soles of the feet, which even leads to a loss of fingerprints. Therefore, it is likely that the security system does not use the finger-prints of a person as a metric for authentication.

For once, the whys are turning out to be more important than the hows. A study shows that consumers who become fixated on how to achieve a goal probably face more difficulty in achieving their aims than people who think abstractly about why they want to do something. The authors of the study conducted four experiments to examine consumer behavior when it came to the goal of saving money. In one such experiment, some people were asked to make a specific plan to save money, whereas others were not asked to plan. Then some people were asked to focus on why they wanted to save money. Later on all participants were given the opportunity to buy candy. Subjects who were thinking concretely and formed a specific plan were less able to avoid the candy purchase than those who had not formed a plan at all.
 To elucidate the results, the authors cite the instance of person who wants to save money and hence makes a plan for achieving this goal. This person plans to save money by purchasing fewer clothing items at the mall. On investigating how this plan influences the person's response to other money-saving opportunities, for example, would the person be more likely to order a cheaper meal at a restaurant, avoid making an impulse purchase, or combine errands to save money on gas etc., the authors found that when people focus on concrete aspects of how they want to achieve goals, they become more closed-minded and consequently less likely to take advantage of opportunities that fall outside their plans. In contrast, people who focus on the why aspect are more likely to consider out-of-plan opportunities to achieve their goals.
Furthermore, in the same experiment, the group that performed the best was the one that was asked to focus on the “why” and had formed a plan implicitly.   Accordingly the authors conclude that planning is more effective when people plan with the complete understanding of “why”.    They suggest that this strategy is particularly effective when the original plan turns out to be unrealistic in terms of feasibility or when other goal-directed activities become available.
Which of the following is an example of a scenario in which the strategy suggested by the authors of the study in the last sentence of the passage would be most effective?
