Ya the test makers knew what they were doing putting this at the end of the section. I didn't completely read the question and answered it as a Must be True. A is obviously the answer because "Most parts of a certain country" so more than half are either not humid or not cold. A is wrong because half the country can't be both humid AND cold if it states that MORE than half are not humid or not cold

I was able to narrow down the answer choice to C and A and ultimately chose C because it seemed the most descriptive of the role the sentence played in the argument. I decided not to choose A because of "adopting a policy". I chose C but didn't feel too confident about it because of "hypothesis".

However after further review, the rest of C also doesn't make sense. The teacher does not provide additional evidence for how athletics can increase a child's strength and coordination. The role structure of the argument is as follows: "Participating in..." is reason 1 FOR the conclusion. "As critics point out..." is an opposing viewpoint. "Yet, since..." is counterclaim and reason 2 FOR the conclusion. "funding for children's..." is the main conclusion
