Question

The importance of sleep is often overlooked by students when they are preparing for exams. Research has consistently shown that sleep deprivation greatly reduces the ability to recall the material learnt. Hence, cutting down on sleep to study longer hours can be counterproductive.

Which one of the following statements is the $\text{CORRECT}$ inference from the above passage?

• A. Sleeping well alone is enough to prepare for an exam. Studying has lesser benefit.
• B. Students are efficient and are not wrong in thinking that sleep is a waste of time.
• C. If a student is extremely well prepared for an exam, he needs little or no sleep.
• D. To do well in an exam, adequate sleep must be part of the preparation.

Answer 1

• A. Sleeping well alone is enough to prepare for an exam. Studying has lesser benefit.
  No where in the passage this is implied. The given passage only says that “sleeping well” is a necessity. It doesn’t say sleeping well is “sufficient” to prepare for an exam.
• B. Students are efficient and are not wrong in thinking that sleep is a waste of time.
  This is contradictory to the given passage.
• C. If a student is extremely well prepared for an exam, he needs little or no sleep.
  False. “sleep deprivation greatly reduces the ability to recall the material learnt.”
• D. To do well in an exam, adequate sleep must be part of the preparation.
  True. “cutting down on sleep to study longer hours can be counterproductive”

Correct option: D.
