I was hesitant because I think it is an assumption for one to make to assume that their present condition cannot be seen as they appeared = cleaning them will allow people to see their original conditions.

For these RC except questions, I find the MSS and infer question LR methods very helpful and applicable. Before looking at the ACs, I will find whatever is absolutely WRONG / NOT SUPPORTED by the group in the question stem and then hunt for that answer.

Alternative explanations:

• if AC confirms possibility of the alternative, then the argument is weakened

• If the AC eliminates the possibility of the alternative then the argument is strengthened.

I mistakenly identified plants that are guaranteed to be disease-free as plants that are disease-free. Companies can guarantee that their food is disease-free, but still have their food carrying diseases, just like how I can promise to work hard today, but still end up scrolling reels.

Eliminated till the last choice and got super confused why this question has to do with guarantees.

It's possible but is not logically followed by the stimulus.

I chose C. However, Lurano doesn't say anything about research money being wasted. In order to make an assumption about her opinion on the research money, one needs to make two assumptions:

1. that lurano thinks money is not that important compared to the safety of the researchers

2. If money is less prioritized as an issue, then it is not wasted.

E, on the other hand, only makes the first assumption, so it is more likely to be supported as a point of disagreement.

Crazy to see how the CR just naturally translates to lawgic in my brain at this point.

@LiviaLSAT The indicator works, but it is important to be aware of the grammar and what it is modifying. In this sentence, "necessary" modifies fundamental knowledge.

I don't understand why B is correct, specifically how we can know that the purpose of a theory is to acquire knowledge.

Good argument, except that I would point out that this argument depends on the assumption that all Genie+ past pass is downloaded via the Disney App. If negated, Walt could have had the paper pass in some other way that does not require one to offer the propitations nor prostrate before the altar.

@brandonsimon2018983 I had the same issue! I later understood that I didn't realize that students finding computer useful for studying arithmetic, while not so helpful for other subjects is a more detailed description of the mixed reaction itself. I understood the last sentence as a background information that is supposed to be combined with one of the answer choices to create an unmentioned mixed reaction (i expected mixed reactions to be something more subjective than "useful", like: some students like computer learning but not others)

The opposite of arriving more than five minutes late is arriving just five minutes or less than five minutes late.

@jakekane the contrapositive works! If the pool does not open before noon, then there must be no children under the age of 6 in the neighborhood, because everyone in the neighborhood is permitted to swim at the pool.

@duvallj4 Maybe polyaspartate is scarce, but we don't know that it is also true for the "raw material from which polyaspartate is made."

The author perhaps mentioned that the evidence is not strong enough because it's indirect. However, the author still thinks that they are good enough to suggest that the neutrino has mass. The last paragraph also discusses how this finding about the mass of neutrinos is sufficient to alter our understanding of the universe, further confirming that the author's attitude should be positive.

@DavidCutie I don't agree that the reason why we don't choose C is becuase it talks about something that is accounted for. I hesitated between C and E and eventually chose C because it accounted for something that the argument didn't establish. The stimulus argument is currently weak because it doesn't establish that elder Singaporeans eat Curry regularly. With C, we can infer that at least such a tumeric-cognitive function relationship is present among the Indian descendants. Even though it doesn't explain why this relationship is the strongest among them, it strengthens the argument by resolving a necessary assumption in the argument.

While E strengthens the "this relationship is the strongest" part, it not only fails to address the necessary assumption (NA) that is stated in C but also relies on this missing NA, making C a better answer.

I was originally also confused about the same thing, but then realized that A is suggesting a new logical condition in which "actually experiencing the emotion" is the necessary condition, and I don't think that is inferable from the stimulus without any assumptions.

@isam I had the same concern, but I think it is explicitly stated in the stimulus that the inaccuracy is due to political pressures (political pressure --> accuracy) and that the health ministry should not release the scientific assessment. There is a gap between how releasing these assessments has to do with accuracy, and that is what the correct answer explains.

I chose A because when reading the stimulus I noticed that the gap of reasoning from premise to conclusion is that the premise is suggesting a research result of babies, while the conclusion is making an overgeneralizing statement about the whole human kind. So I thought A would strengthen the argument for sure.

however, B strengthens the argument more because it provides a necessary assumption required for the conclusion: if the babies in the experiment had previous exposure to music from other cultures (if we negated AC B), we can not reach to the conclusion that such preference comes from biological predispositions.
