Read the passage and answer: Sleep is essential for human health, with most adults needing 7-9 hours per night for optimal function. During sleep, the body repairs tissues, consolidates memories, and regulates hormones. Chronic sleep deprivation has been linked to numerous health problems including obesity, diabetes, cardiovascular disease, and weakened immune function. Despite this, surveys show that approximately one-third of American adults regularly fail to get sufficient sleep. According to the passage, what percentage of American adults regularly fail to get sufficient sleep?

Correct answer

About 33% (one-third)

  1. A 10%
  2. B About 33% (one-third)
  3. C 50%
  4. D 90%

Why this is the answer

The passage states 'approximately one-third of American adults regularly fail to get sufficient sleep.' One-third = approximately 33%. Recognize equivalent expressions: one-third = 1/3 = ~33%; one-quarter = 1/4 = 25%; one-half = 1/2 = 50%; one-fifth = 1/5 = 20%. Detail questions may ask in different terms than the passage uses; recognize numerical equivalents. Other detail-question strategies: (1) For 'who' questions — look for proper nouns and pronouns; (2) For 'when' questions — look for dates, time references; (3) For 'where' questions — look for places, locations; (4) For 'how many/much' questions — look for numbers, quantities; (5) For 'why' questions — look for reasoning, causes (often signaled by 'because,' 'since,' 'due to').
