The evolution of intelligence among early large mammals of the grasslands was due in great measure to the interaction between two ecologically synchronized groups of these animals, the hunting carnivores and the herbivores that they hunted. The interaction resulting from the differences [Line 5] between predator and prey led to a general improvement in brain functions; however, certain components of intelligence were improved far more than others.
The kind of intelligence favored by the interplay of increasingly smarter catchers and increasingly keener escapers is defined by attention — that aspect of mind carrying consciousness forward from one moment to the next. It ranges from a passive, [Line 10] free-floating awareness to a highly focused, active fixation. The range through these states is mediated by the arousal system, a network of tracts converging from sensory systems to integrating centers in the brain stem. From the more relaxed to the more vigorous levels, sensitivity to novelty is increased. The organism is more awake, more vigilant; this increased vigilance results in the apprehension of ever more subtle signals [Line 15] as the organism becomes more sensitive to its surroundings. The processes of arousal and concentration give attention its direction. Arousal is at first general, with a flooding of impulses in the brain stem; then gradually the activation is channeled. Thus begins concentration, the holding of consistent images. One meaning of intelligence is the way in which these images and other alertly searched information are used in the context [Line 20] of previous experience. Consciousness links past attention to the present and permits the integration of details with perceived ends and purposes.
The elements of intelligence and consciousness come together marvelously to produce different styles in predator and prey. Herbivores and carnivores develop different kinds of attention related to escaping or chasing. Although in both kinds of [Line 25] animal, arousal stimulates the production of adrenaline and norepinephrine by the adrenal glands, the effect in herbivores is primarily fear, whereas in carnivores the effect is primarily aggression. For both, arousal attunes the animal to what is ahead. Perhaps it does not experience forethought as we know it, but the animal does experience something like it. The predator is searchingly aggressive,inner-directed, tuned by [Line 30] the nervous system and the adrenal hormones, but aware in a sense closer to human consciousness than, say, a hungry lizard’s instinctive snap at a passing beetle. Using past events as a framework, the large mammal predator is working out a relationship between movement and food, sensitive to possibilities in cold trails and distant sounds — and yesterday’s unforgotten lessons. The herbivore prey is of a different mind [Line 35] . Its mood of wariness rather than searching and its attitude of general expectancy instead of anticipating are silk-thin veils of tranquillity over an explosive endocrine
system.

    provide an additional illustration of the brutality characteristic of predators
  • e)
    offer an objection to suggestions that all animals lack consciousness
Correct answer is option 'C'. Can you explain this answer?
Most Upvoted Answer
Directions: Refer to the following passage. After reading the passage...
Choice C is correct. The “hungry lizard’s instinctive snap” is contrasted with the mammal’s higher level of awareness. Choices A and B are incorrect. The example of the hungry lizard provides a contrast; it does not demonstrate a similarity or extend the author’s argument. Choices D and E are incorrect. Brutality is not mentioned in the passage as a characteristic of predators, and there is no suggestion that all animals lack consciousness.

Explanation:

Distinction between higher and lower levels of consciousness:
The author refers to a hungry lizard in order to make a distinction between higher and lower levels of consciousness. The passage contrasts the consciousness of large mammal predators, which involves a certain level of awareness and forethought, with the instinctive snap of a hungry lizard. This comparison highlights the varying degrees of consciousness and intelligence exhibited by different types of animals.

Illustration of different levels of consciousness:
- The mention of a hungry lizard serves to illustrate a lower level of consciousness compared to the large mammal predators discussed in the passage.
- The hungry lizard's instinctive behavior is contrasted with the more deliberate and strategic actions of the mammal predators, emphasizing the differences in cognitive abilities among different species.

Emphasis on the complexity of consciousness:
- By including the example of the hungry lizard, the author underscores the complexity and diversity of consciousness in the animal kingdom.
- This example reinforces the idea that consciousness is not a uniform trait across all species, but rather exists on a spectrum with varying levels of awareness and cognitive abilities.

Directions: After reading the passage, read and respond to the questions that follow by selecting the best choice for each one.[1] An atmospheric gas that absorbs and emits thermal radiation in the infrared range is known as a greenhouse gas. [2] Without such gases, the surface temperature of the earth would have been a frigid -18°C instead of the current 15°C. [3] Many climate scientists claim that human activities since the beginning of the Industrial Revolution have led to a steady increase in the atmospheric concentration of many greenhouse gases, with a consequent increase in the planet's surface temperature by about 0.85°C in the last 130 years. [4] However, in order to correctly estimate the anthropogenic changes in earth's surface temperature, it is important to quantify the effect of external natural factors like large volcanic eruptions on the planet's surface temperature.[5] Though volcanic eruptions emit carbon dioxide, a greenhouse gas, the atmospheric concentration of this gas is about 16000 times the amount released by volcanic eruptions; therefore, no matter how large a volcanic eruption is, it cannot produce a significant change in the atmospheric carbon dioxide levels. [6] Further, the total amount of carbon dioxide emitted per year by volcanic eruptions – between 130 and 230 million tons – is roughly equivalent to that emitted in only three to five days of human activity.[7] It is mainly through the emission of sulfur dioxide gas and ash particles into the atmosphere that large volcanic eruptions affect earth's surface temperature. [8] Sulfur dioxide reacts with the water vapor present in air to form fine particles called sulfate aerosols. [9] Winds spread the cloud of aerosols and ash particles around the globe in weeks. [10] These particles absorb incoming solar radiation and scatter it back into space, thereby producing a cooling effect on the earth. [11] They take several years to settle out of the atmosphere and thus impact the global surface temperature for many years. [12] Robock and Mao have shown that for two years after a great volcanic eruption, the surface temperature decreases by 0.1 – 0.2°C. [13] The 1991 Pinatubo eruption in Indonesia was one of the largest volcanic eruptions in the twentieth century and resulted in a global surface cooling of 0.5°C for about two to four years after the eruption.[14] The El Chichón eruption in 1982 was the first major eruption whose climatic impact was studied in detail by modern instruments. [15] Though the emission volume of this eruption was similar to the Mount St. Helens eruption in 1980, El Chichón released seven times the amount of sulfate aerosols released by Mount St. Helens and lowered the earth's temperature by about 0.4°C as against a decrease of only 0.1°C for Mount St. Helens.Q. Which of the following statements, if true, will best support the assertion that a large volcanic eruption does not contribute to warming of the earth's surface?

The herbivore prey is of a different mind [Line 35] . Its mood of wariness rather than searching and its attitude of general expectancy instead of anticipating are silk-thin veils of tranquillity over an explosive endocrinesystem.Q.

Here you can find the meaning of Directions: Refer to the following passage. After reading the passage, read and respond to each question selecting the best answer choice for each one.The evolution of intelligence among early large mammals of the grasslands was due in great measure to the interaction between two ecologically synchronized groups of these animals, the hunting carnivores and the herbivores that they hunted. The interaction resulting from the differences [Line 5] between predator and prey led to a general improvement in brain functions; however, certain components of intelligence were improved far more than others.The kind of intelligence favored by the interplay of increasingly smarter catchers and increasingly keener escapers is defined by attention — that aspect of mind carrying consciousness forward from one moment to the next. It ranges from a passive, [Line 10] free-floating awareness to a highly focused, active fixation. The range through these states is mediated by the arousal system, a network of tracts converging from sensory systems to integrating centers in the brain stem. From the more relaxed to the more vigorous levels, sensitivity to novelty is increased. The organism is more awake, more vigilant; this increased vigilance results in the apprehension of ever more subtle signals [Line 15] as the organism becomes more sensitive to its surroundings. The processes of arousal and concentration give attention its direction. Arousal is at first general, with a flooding of impulses in the brain stem; then gradually the activation is channeled. Thus begins concentration, the holding of consistent images. One meaning of intelligence is the way in which these images and other alertly searched information are used in the context [Line 20] of previous experience. Consciousness links past attention to the present and permits the integration of details with perceived ends and purposes.The elements of intelligence and consciousness come together marvelously to produce different styles in predator and prey. Herbivores and carnivores develop different kinds of attention related to escaping or chasing. Although in both kinds of [Line 25] animal, arousal stimulates the production of adrenaline and norepinephrine by the adrenal glands, the effect in herbivores is primarily fear, whereas in carnivores the effect is primarily aggression. For both, arousal attunes the animal to what is ahead. Perhaps it does not experience forethought as we know it, but the animal does experience something like it.
