Direction: Read the following passage carefully and answer the questions given below it.
Pancreatic beta cells are responsible within a body for monitoring homeostatic cues from a wide variety of hormonal inputs and in turn regulate the insulin needed to maintain balance in the blood sugar.Researchers studying this signaling system have located three key proteins that relay signals. Understanding how these proteins function within the context of the signaling system can help scientists gain more insight into how diabetes compromises the healthy functioning of the system and how to counteract the impact of diabetes once it is identified.
Q. According to the passage, each of the following is true EXCEPT:
  • a)
    The pancreas helps a body to maintain homeostasis.
  • b)
    Diabetes controls the functioning of pancreatic beta cells.
  • c)
    When the pancreas is stimulated, it releases varying amounts of insulin that help to balance blood sugar.
  • d)
    Pancreatic beta cells must interpret a wide array of hormonal information.
  • e)
    Blood sugar can be controlled by insulin.
Correct answer is option 'B'. Can you explain this answer?

The four wrong answers to this Detail question are found in the passage. The correct answer will either contradict or distort the passage, or fall outside its scope altogether. Choice (A) is true; it is stated in the first sentence of the passage. Choice (B) seems like it might be true, but reading carefully, it overstates the role of diabetes as described in the passage: diabetes compromises or impairs the ability of the pancreatic beta cells to function, but you’re not told that it controls those functions. Choice (C) is true and is also stated in the passage’s first sentence. Choice (D) paraphrases the first main claim of the passage. Choice (E) comes from the end of the first sentence.

Directions: Answer the questions based on following reading passage.Some researchers contend that sleep plays no role in the consolidation of declarative memory (i.e., memory involving factual information). These researchers note that people with impairments in rapid eye movement (REM) sleep continue to lead normal lives, and they argue that if sleep were crucial for memory, then these individuals would have apparent memory deficits. Yet the same researchers acknowledge that the cognitive capacities of these individuals have never been systematically examined, nor have they been the subject of studies of tasks on which performance reportedly depends on sleep. Even if such studies were done, they could only clarify our understanding of the role of REM sleep, not sleep in general.These researchers also claim that improvements of memory overnight can be explained by the mere passage of time, rather than attributed to sleep. But recent studies of memory performance after sleep—including one demonstrating that sleep stabilizes declarative memories from future interference caused by mental activity during wakefulness—make this claim unsustainable. Certainly there are memory consolidation processes that occur across periods of wakefulness, some of which neither depend on nor are enhanced by sleep. But when sleep is compared with wakefulness, and performance is better after sleep, then some benefit of sleep for memory must be acknowledged.Q. According to the author of the passage, which of the following generalizations about memory and sleep is true?

Directions: Answer the questions based on following reading passage.Until recently, many anthropologists assumed that the environment of what is now the southwestern United States shaped the social history and culture of the region’s indigenous peoples. Building on this assumption, archaeologists asserted that adverse environmental conditions and droughts were responsible for the disappearances and migrations of southwestern populations from many sites they once inhabited.However, such deterministic arguments fail to acknowledge that local environmental variability in the Southwest makes generalizing about that environment difficult. To examine the relationship between environmental variation and sociocultural change in the Western Pueblo region of central Arizona, which indigenous tribes have occupied continuously for at least 800 years, a research team recently reconstructed the climatic, vegetational, and erosional cycles of past centuries. The researchers found it impossible to provide a single, generally applicable characterization of environmental conditions for the region. Rather, they found that local areas experienced different patterns of rainfall, wind, and erosion, and that such conditions had prevailed in the Southwest for the last 1,400 years. Rainfall, for example, varied within and between local valley systems, so that even adjacent agricultural fields can produce significantly different yields.The researchers characterized episodes of variation in southwestern environments by frequency: low-frequency environmental processes occur in cycles longer than one human generation, which generally is considered to last about 25 years, and high frequency processes have shorter cycles. The researchers pointed out that low-frequency processes, such as fluctuations in stream flow and groundwater levels, would not usually be apparent to human populations. In contrast, high-frequency fluctuations such as seasonal temperature variations are observable and somewhat predictable, so that groups could have adapted their behaviors accordingly. When the researchers compared sequences of sociocultural change in the Western Pueblo region with episodes of low- and high-frequency environmental variation, however, they found no simple correlation between environmental process and sociocultural change or persistence.Although early Pueblo peoples did protect themselves against environmental risk and uncertainty, they responded variously on different occasions to similar patterns of high frequency climatic and environmental change. The researchers identified seven major adaptive responses, including increased mobility, relocation of permanent settlements, changes in subsistence foods, and reliance on trade with other groups. These findings suggest that groups’ adaptive choices depended on cultural and social as well as environmental factors and were flexible strategies rather than uncomplicated reactions to environmental change. Environmental conditions mattered, but they were rarely, if ever, sufficient to account for sociocultural persistence and change. Group size and composition, culture, contact with other groups, and individual choices and actions were— barring catastrophes such as floods or earthquakes—more significant for a population’s survival than were climate and environment.Q. It can be inferred from the passage that which of the following activities is NOT an example of a population responding to high-frequency environmental processes?
