This section alone has four weaken questions!!! I don't think i've ever had a section with so many flaw and weaken questions together... anyway, since JY's explanation videos are not available yet, I want to put these confusing ones out here for discussion:
Q22
Premise: (because) if we want to know medieval epi includes some claims, we just ask whether any epi believe it. If they did, then it is part of medieval epi; if they didn't then the opposite is part of medieval epi.
Conclusion: The solution to define medieval epistemology simply as the epistemological beliefs of the medieval epistemologists.
The correct AC is E, however I feel like E is weakening the premise. since we're supposed to weaken the support in this type of questions, I'm not sure E does that and also this argument feels like circular reasoning to me. Please feel free to point out any problems in my breakdown of the argument.
Q24
premise: if pollen from a drug-producing crop flies into a nearby non-drug-producing crop of the same species, the drug could fertilize and turn it into a drug-producing crop.
conclusion: genetically engineered crop raises the possibility that drug will end up in the general food supply.
I chose E for this question, becuz i think E provides that even though X happens, doesn't mean Y will necessarily ensue (X, not Y).
Similar to Q22, I find the correct answer choice D to weaken the premise, instead of the support.
It is so weird that the way I look at (B) is that it's ruling out an alternative explanation. I thought that "unusual levels of unrest" could be another cause leading to the "decline and fall of Rome". But it seems to be the same thing as "decline and fall of Rome" right? Also I see why (D)is the ultimate correct answe choice, but (B) under time pressure just seems so cookie-cutter!
