Answer Choice A

It took me a second but I ruled out answer choice A because what it strengthens in the correlation described in the stimulus, not the hypothesis. Is this correct or is there another reason you can see that it's wrong?

What it strengthens *is* the correlation

Tehran's explanation from 2018 is also really good I didn't consider that.

Hi, I'm not actually sure that it does strengthen the correlation. It's showing that on aggregate, family size decreasing is correlated with increasing allergies, but we do not know if this hold true at the family level. Maybe the increase in allergies was concentrated in adults, and allergies actually become less common for kids. Maybe allergies become more common for people in the larger families. The aggregate does not tell us enough about the more micro level trends.
