Negating B

I tried posting this to the other thread but it would not load... If we negate answer choice B how does that not also destroy this entire argument? Is it because "time" is only mentioned by the parents?

Hello @Jwebb,

Answer choice B states: "Teachers generally devote the same amount of individualized attention to each student in a class."

This does not mention class size, which means that it applies to classes with more than 20 students as well as classes with a 20 student maximum. Even if the teacher pays more attention to some students than to others, they would still be able to spend more time per student in the smaller class than in the larger class. This does not affect the argument of the parents.

In addition, this assumption is largely irrelevant to the argument made by the researchers. The researchers have already acknowledged that teachers spent more time with individual students. We do not require an assumption about this. We need something that links the researchers' conclusion about grades and the student engagement level. This is provided by answer choice D.

That clears it up. Thank you.
