@MaxThompson how is one labeling "all of the criticisms of their work by Dr. Q" when the stimulus is only talking about "many"? I guess this ends up being moot to finding the right answer, but I had the same issue as this student.

@Lola I'm no professional, but I don't think so. Even if most (51-100%) people like ice cream, the remaining people still don't like ice cream. Therefore, it's not negated by stating some don't like it. And yes, there's the possibility that "most" COULD mean all, but without further information, that's an assumption. The "some" statement would only negate the case where that assumption happens to be true.

@JenniferQin I also translated it using some-not. Some small animals do not move faster than large animals (which you can take further to say some small animals are as fast or less fast). This expresses the same ideal as the given answer (large are equally fast or faster). I think the given answer is clearer now that I've seen it.

@nfbuckley2003 yes. It's just unlike that you'd need or want to work with /prohibited as the sufficient condition

@jasminea0903 I agree that these seem like the same thing. I think they function as different parts of speech that actually convey slightly different meanings or contexts. To see that, try “translating” it with always. “Always [a] NASA program pushes the frontiers…” doesn’t make sense. My brain translates it to “when a NASA program…our collective confidence always swells”. The wording in that ends up using indicators as we would expect.
