In sentence 2 (reproduced below), the writer wants to introduce evidence that will most strongly support the argument.The American Academy of Sleep Medicine has found that teens who do not get 8 to 10 hours of sleep per night are more likely to be sedentary, to have obesity, to have depression, or to participate in high-risk behaviors like using alcohol, tobacco, or drugs.

The American Academy of Sleep Medicine is a specific, credible source, and the sentence accurately attributes the findings to it. Choice B overstates the evidence by saying it “proves” the claim, while C gives a less specific source and changes the sleep threshold. Choice D offers no source for the evidence. Therefore, keeping the sentence as written best supports the argument.
