is it fair to say for these that you are looking for an answer that mentions either the conclusion or the premise as supporting the conclusion? alot of the correct answers seem to be either one of these, and the other trap wrong answers mention something about the statement but not that its directly related to the conclusion.

this is gross to think about

This was helpful!! now just how to do this on the actual exam lol

this was super helpful. it is still so annoying!

amazing! so great. love the drill sections and the mix of video and reading and reading only is great to mix up learning technique

great comment! many implies some, while some does not imply many

i thought this too! i think if youre using unless as the indicator to tell you to negate and make sufficient, the sentence should translate easily. i think the lesson is just ensuring/clarifying importance of doing this that you do not forget other parts to the complex logical sentence

i think the notion is a bit confusing here. it makes the xA in the second line appear as if you are trying to say, "not A", and then conclude that "not B". however, this is not true. by denying not A, you cannot conclude not B. i dont think you think that is correct based on the actual example here, but the notion on this page and further ahead in "Formal Arguments #1 - #3 Review

Lesson 32 of 47, 3m", you make the same misleading notation.

i think the sentence is pretty ambiguously written tbh.
