IPMAT Indore 2023 - VA Q49 Explanation

Explanation:

(a)

The passage discusses the negative consequences of sleep deprivation, and one of the highlighted outcomes is mental exhaustion. Sleep deprivation adversely affects both the mental and physical well being of an individual.

The passage mentions that insomnia, which is a form of sleep deprivation, can make the body work abnormally. It affects both mental and physical abilities, leaving the brain exhausted. The exhaustion of the brain, in turn, affects the natural functioning of the body. Therefore, mental exhaustion is a significant consequence of being deprived of sleep, as indicated in the passage.

Option 1, "mental exhaustion," aligns with the information provided in the passage, making it the correct answer. The passage does not specifically mention hunger satiation, terminal illness, or metabolism loss as direct consequences of sleep deprivation.

Explanation for other options: Option 2, "hunger satiation": The passage discusses how sleep deprivation can lead to an increase in the hunger hormone (ghrelin) and a decrease in the satiety hormone (leptin), which can result in increased appetite and potential overeating. However, it does not mention "hunger satiation."

Option 3, "terminal illness": The passage does not suggest that lack of sleep directly leads to terminal illness. While it mentions the consequences of sleep deprivation on health, it does not specify terminal illnesses.

Option 4, "metabolism loss": The passage mentions that sleep deprivation can lower levels of leptin, a hormone that stabilizes metabolism. However, it does not explicitly state "metabolism loss" as a consequence of sleep deprivation.
