Explanation:

I do not know the lesson the question is based on but this should be the correct answer. In today's very high paced world, adults are having to do more work to be able to take care of their responsibilities. This gives them less time to sleep thereby leading to sleep problems.

Indeed studies show that over 50 million American adults have some sort of sleep problem with the CDC estimating that 1 out of 3 adults are sleep deprived which is quite alarming because apart from the primary effect of fatigue, sleep deprivation can lead to increased risk of obesity, diabetes, and other serious health complications.
