If you have a statement that says, "Not all A's are C's," then why can't negating that statement be "No A's are C's" in addition to "Some A's are not C's?"

Hi, I am still confused on how choice D doesn't weaken the argument? Choice A seems like a weak answer choice doesn't it?

Can someone please explain this question I got the original and blind review answer wrong, and I am just very confused on how you come to the conclusion of "E" being the correct answer choice.

I got the answer right, but why is it right

Any tips on getting faster at RC? I'm trying to read each passage in 4min and answer questions in 4 min, but I am finding that I still take too much time on answering the questions. Should I spend less time reading?

How can you tell the level of difficulty for the passages in the RC section? I know the passages have gotten more difficult recently and they are not necessarily in the order of easiest to hardest? Should we attack the passages with the most questions first? Or should we just go through in the order provided?

In Answer Choice A, it states that the shortage of courtroom space was not experienced until 1990. This is not consistent with the passage (when Mayor Tyler claims that they experienced a shortage in 1982). How can this answer be correct if the facts are inconsistent with the passage.

I answered C for this question, when the answer was B, but I'd like further review on this answer.

Hi, I had a quick question about denying the link between premise and conclusion.

In this video: https://classic.7sage.com/lesson/egyptian-and-mayan-pyramids-flaw-question/

JY talks about how denying the argument by denying the link between the premise and conclusion is not the same as denying the conclusion. In the particular question, the author denies the link between premise and conclusion but is not allowed to deny the conclusion.

When are you ever allowed to deny the conclusion? Or are you not allowed to usually?

Thanks.

Confused on how questions work -- I've done two drills now where I think I select an answer (the circle is blue) but only my first answer out of all of them is counted, while the rest are N/A.

I am having the hardest time understanding how E is the answer to this one. It was an answer I dismissed outright because I didn't see what the healthcare had to do with the murder rate. Perhaps the question was phrased weird, but I can't figure how to work it in my brain. Any advice?

can someone explain why it a and not c?

If someone could explain their reasoning behind how they reached the correct answer to this question it would be much appreciated.

Suppose we had a rule 6 situation where B goes to A and C goes to A, but B also goes to D and E goes to C. What happens if there are other pieces in the chain (for example, the D and E) when you take the contrapositive of the rule 6 group (A, B, C)? Do you also take the contrapositive of those? Like basically taking the contrapositive of the whole entire thing?

What does "presuppose" ACTUALLY mean in an AP question's answer choice?

I understand that presupposing something is similar to assuming something. But I still keep messing up on AP questions where the answer choices include the word "presuppose." I trick myself into believing that the argument has presupposed something!

For example, PT27.S2.Q17 (the "A Stable Society" question), I picked E :'(

Does anybody have any examples of when an argument really did presuppose something? Are answer choices in AP questions that mention "presupposing" always wrong?

Any advice would be greatly appreciated.

MMS question

I got this one wrong twice, the first time I picked D, this is not supported because we don.t know anything about the algae, only that they are the food source of the mussels, so we cannot infer anything else. In Blind review I choose C, also wrong answer, cause we don't know if there is any mechanical means available for cleaning the pipe.

This is a weakening question type. The argument is stating that Bruno must have been a spy, the premise says that the spy was the only clergyman working at the embassy at that time. The assumption to make the argument week must be A, cause its stating that Bruno was no longer a clergyman once he started working at the embassy.

When I do Necessary Assumption Question, I prefer to negate the Answer Choice and then test whether the argument becomes invalid. But this question confused me. Can anybody help me explain the question by negating and testing?

Can anybody explain E? If I negate AC(E), why the argument becomes invalid?

when JY says to print "ten clean copies" of games in order to memorize the inferences of games, which games is he talking about? just the games featured in the videos in the LG core curriculum? or is he talking about those AS WELL as the games in the problem sets? and if hes also talking about the games in the problem sets, how many of those is he talking about?

i like the idea of doing a game repeatedly and unremittingly until ive memorized it. i just dont know on which games im supoosed to be practicing this strategy. thank you

any tips and tricks for making it through the 2 LR sections? i find myself losing concentration even halfway of just 1 timed full section. i don't experience this type of burnout during RC and not as much with LG. when i drill LR with 5-10 questions at a time, i don't have as much of an issue with focusing and accuracy. but as soon as i do an entire timed section, i find myself messing up even early on in the section. i must just be overwhelmed by the mass amount of varying subject matter in LR

B, to me, seems as the right answer. Can someone explain to me why is it D?

Ok I understand why the answer I marked, C was incorrect, specifically because of the last part of the sentence says "some clearly never were". However, the correct answer choice, option D also confuses me because it says that small amounts of the Co2 entered the soil from the atmosphere. The confusing part in all this is that the premise says the plants make the Co2 and put it into the atmosphere, so I do not understand completely why option D is correct. I understand why my answer of option C was incorrect, however.

Does anyone have a good template for their wrong answer journal for reading comprehension?
