Can someone please explain to me why the answer is A? I originally chose C because in the first paragraph, it says that assimilation is related to worse health. So since Mexican immigrants reported poor health, then won't that they are more assimilated?
I agree that this is not the best question, but by “based on other results reported in the passage,” I think the question is directing you to the results in the last paragraph, which says SES was the only factor that partially affected the association.
I think you got caught up in the first paragraph where they said in general assimilation = worse health. However, the question asks about this study specifically, where "the researchers did not find that assimilation...affected the language-health relationship" but instead found one between SES and health.
