Answer: C
Step-by-step explanation:
Statement A says after school sports help with teamwork, and that is good to learn for a student. Since that is talking good about after school sports, and not negatively A isn't the answer.
Statement B says only studying is foolish, and something the school provides is best rather than doing something the school doesn't provide. Since they are saying school provided after school activities (such as sports) are better, and not worse B isn't the answer.
Statement D says pretty much the same thing as B, except reworded, saying after school sports is a good break after studying all the time. And since it's not B, it cant be D either.
That leaves statement C, which tells the benefit of after school sports, but comes to their reason that they distract from the students learning, so they are bad. While they are mentioning the benefit, from their argument, the are responding to counterclaim (the rebuttal). In other words, they are responding to the other side's argument, restating their reason, and explaining why they are wrong. Thus, C is correct.
Hope that helped a lot.
