This question really threw me off. It talks about how the goal of medicine seems to be extend life indefinitely; it then gets into organ transplants, and how the brain can't be transplanted.

I'm sure I'm missing something obvious, but for whatever reason I couldn't wrap my brain around this one. Can anyone explain why people with degenerative brains disorders will make up an ever-increasing proportion of the population? (the conclusion of the argument). And can anyone explain why the correct answer is C?

If anyone can help, thanks!
