Hi LSAT Rat,
This is one of the very tricky Weaken questions that tend to come up at the end of an LR section. This stimulus is trying to prove that there is no causal connection between environment and likelihood of teenagers to participate in sports. As a Weaken question, this means we have to actually strengthen the causal linkage between environment and teenage sports, so the correct answer choice here must show this link in some form, however slightly.
Answer choice (D) does this by giving some, very slight, counterevidence to the idea that environmental factors play no role in teenage sports; if the participation rate varies widely across societies and time periods, then that implies that different societal environments do play a role, even if family or school environments do not. Essentially, the stimulus has shown two potential environmental factors to have no effect, and uses this to claim that no environmental factor has an effect; (D) brings in two more potential environmental factors, time and society, that seem to possibly be having an effect.
(B) actually tends to strengthen the stimulus by showing another instance where family environment seems to have no effect on whether a teen participates in sports, this time when parents are less enthusiastic than the teens are, rather than comparing multiple teens in a family. There are also some hints as to (B) being incorrect: the very vague scope of "some," the teenagers being "more enthusiastic than their parents" at participating in sports (but not necessarily actually enthusiastic enough to participate).
Hope this clears things up!
