I don't know why this trips me up SO BADLY, but I ended up switching this one to the correct answer in my BR.
BUT, I watched the video and I reasoned it differently.
We're taught that, if we're given a premise, we have to take it to be true, correct?
So I reasoned that A is the correct answer over B, because the stimulus says "because it permits a slower and more natural rhythm of life, living in the country...". So, B is wrong because the stimulus TOLD US that it permits a slower rhythm of life, and we can't just conclude therefore it doesn't. Right?

A is supported pretty well because we know that both groups get sick as often as eachother and have equal amounts of stress.
