Still waiting to hear back from quite a few schools (I applied really late in the cycle), but it’s looking like I'll be attending UCLA :)

I'm in the exact same situation!

List of top 25 countries with highest cancer rates. Its all of Europe and plus USA, Australia, and South Korea.

Being wealthier causes you to not die from more preventable diseases and thus get cancer. Being wealthier would cause you to get tested more and thus be diagnosed with cancer more often. It requires assumptions but so does the pollutants. What counts as environmental pollution? Littering? Light Pollution? I think the answer is D because you can make reasonable assumptions to assume that being wealthy would decrease cancer rates, ie less smokers, but that requires more outside knowledge IMO then the assumptions that would lead to an increased rate of cancer. I think this question is a least a little BS, and its certainly reasonable to assume wealth could cause an increase in cancer rates.
