The following text is about athletic performance.
Athletes have long searched for legal ways to enhance performance, and one surprising method has gained scientific support: napping. Sleep researchers have found that a 20-30 minute nap before competition can improve reaction times, alertness, and even complex decision-making. Unlike caffeine, which can cause jitters and disrupt later sleep, a well-timed nap provides benefits without significant drawbacks.
What advantage of napping does the text emphasize compared to other methods?
Napping is completely free of any effects
Napping provides benefits without significant negative side effects
Napping can replace all other training methods
Napping works better for amateur athletes
Correct Answer: B
Choice B is the correct answer. The text compares napping to caffeine, noting naps provide "benefits without significant drawbacks" unlike caffeine's side effects.
- Evidence: Caffeine "can cause jitters and disrupt later sleep" but naps don't.
- Reasoning: The comparison highlights napping's advantage.
- Conclusion: Benefits without drawbacks is the emphasized advantage.
Choice A is incorrect because "without significant drawbacks" isn't the same as no effects. Choice C is incorrect because replacing training is not mentioned. Choice D is incorrect because athlete level is not discussed.
