Explanation:

Identify the question

The question asks: "How does the author concede the counterargument that napping might interfere with night sleep?"

Analyze the options

Let's examine the visible options:

• (A) By explaining that teenagers who get less than 8 hours of sleep at night benefit from naps
• (B) By clarifying the results of the research conducted at Duke-NUS Medical School
• (C) By acknowledging that the value of a nap depends on its length and timing
• (D) By admitting that teenagers rarely meet the recommendations of the sleep scientists

Evaluate the concession

A concession in an argument is when an author acknowledges a valid point made by the opposing side (the counterargument).

• The counterargument is that "napping might interfere with night sleep."
• To concede this point while still supporting napping, the author would logically point out the conditions under which this interference happens or how to avoid it.
• Option (C) directly addresses this by stating that the value of a nap depends on its "length and timing." This acknowledges (concedes) that if a nap is too long or taken too late, it indeed might interfere with night sleep, thereby validating the counterargument under specific conditions.

Confirm the best choice

Option (C) is the most logical rhetorical method for conceding how napping can interfere with night sleep, as managing length and timing is the standard scientific recommendation to prevent daytime naps from disrupting nighttime sleep cycles.

Answer:

• (A) By explaining that teenagers who get less than 8 hours of sleep at night benefit from naps
• (B) By clarifying the results of the research conducted at Duke-NUS Medical School
• (C) By acknowledging that the value of a nap depends on its length and timing (Correct answer)
• (D) By admitting that teenagers rarely meet the recommendations of the sleep scientists
