I took D to mean they were domesticating animals for some reason. Immediately threw it out because of that.

It seems like B is also wrong for more obvious reasons. Finding the solution for the recession does not necessarily equate to improving the economy. At least that’s how I thought about it.

Agreed, was the easiest question in the set.

I think it is strongly implied with the “even if one actually distrusts one’s skills” phrase. Not a fan of this question at all.

took me 6 minutes to get this answer… definitely would skip on the real test lol

I eliminated A for this exact reason. The previous question explanation threw out an answer because only one condition was met.

A video explaining the difference between the use of “only if” in this lesson vs. the last lesson would be helpful for future audiences. The last video made it seem like anytime we see an “only if”, we should throw that answer out in a PSA question. The explanations should be more careful so as not to unintentionally make us think there is a solve-all rule.

I don’t understand how C strengthens the conclusion here. If most injuries are from accidents that stretching would have no effect on, then wouldn’t that mean the researchers failed to control for that factor? Wouldn’t that weaken the conclusion that stretching has no effect on injury prevention?

I get why D is correct, however.
