So if we know for a fact that there is only 1 necessary condition on order for something to occur, and that condition is satisfied, does that make that necessary condition also a sufficient condition (bi-conditional)?
I feel that answer choice C is in fact a generalization as the phrase is generalizing an aspect of many cities. However, the reason I eliminated C was because, although the observation that rainwater runoff picks up oil and other pollutants explains the mechanism for contamination of lakes and rivers from water runoff, the generalization that the pollutants in the rainwater runoff exceeds that from industrial discharge is not based on this observation.
It looks like this question actually had us attack the premise directly as opposed to the support relationship between premise and conclusion.
I asked the same question a little while back and got the below response:

Hey All,
I was just wondering what the average discrepancy between your actual scores vs. your BR scores are after taking a PT. I know I average about a 10pt difference between actual and BR scores. Is that too high of a discrepancy? What should the difference be between scores by the time Test Day comes around? And for those of you who have closed the gap, how have you lessened the gap?
I ended up picking answer choice B but because of the sample size flaw you mentioned answer choice A was trying to resolve. The argument attempts to draw a conclusion about computer users in general by citing a case-study of 70 students. I felt that answer choice B strengthens the argument by saying that other studies have shown these same results in most computer users. This answer choice now eliminates the small sample size issue in the argument and therefore strengthens it.
Exactly the same reason I eliminated A during BR. I'm not so sure about the accuracy of the explanation for this question.
Have you tried working through the LSAT Trainer's RC section? It shows you exactly what aspects of reading comp passages to focus on (mainly passage structure). It definitely put things in perspective for me.
Hi JY,
Can you please address jaeyong777 concern below? I had the exact same thought process which led me to believe that none of the answers were supported in this question. Thank you!
The way I eliminated A was because the argument never mentions what is "promising for small-scale construction". All we are told is that those who work with papercrete in small scale construction believe that it would be effective for large scale construction. Without mentioning what is promising for small scale construction, we can't confuse it with what is promising for large-scale construction.
I would say it's unlikely that your skill are "100% test ready" until you get through a couple of PTs. I feel like the curriculum and drilling gives you the framework to begin taking the PTs under timed conditions and it's when you blind review these PTs that you can identify your errors in reasoning while under pressure. From personal experience, I would say that I was a little foggy on some of the concepts until I started PTing and blind reviewing. I think it's through repetition and finding your flaws under timed conditions that you really sharpen your skills.
Couldn't answer choice B be referring to the assumption that one is either happy or unhappy?
I feel like if you treat this question stem as a sufficient assumption, the answer choice is much clearer. Just linking the major premise to the main conclusion leaves you with exactly what answer choice A is saying.
Would someone be able to shed a little more light on why answer choice D is wrong? Is it simply because the answer choice includes a premise and not only the conclusion?
I chose C because I reasoned that before the ethics violations, 52% of people thought Walker was a good mayor. But, after the ethics violations came out, maybe that number could have dropped by 20% had it not been for the ignorant 20% people who who had no idea Walker had committed ethics violations. This would make the 52% before the ethics violations equivalent to the 52% after the ethics violations. Can someone help me correct my reasoning??
I ended up choosing A but was very hesitant in picking it because it requires us to make the assumption that triggering the part of the brain that controls self defense makes us more likely to catch the ball. What if triggering that part of the brain actually causes us to swat the ball away (in self defense)? I feel like I got lucky that the other answer choices weren't even close.
Hi ssaverese,
For the purposes of the LSAT, the word "many" is equivalent to the word "some". As for a numerical range, it could be between 1 and 100 if the set consists of a total of 100. When I'm doing LR questions, I substitute the word "many" for "some" because, in my mind, I can sometimes incorrectly interpret the word "many" to be "most".
This might be a little late but maybe this can still help if you are still studying. The regular translation of the word few is some are but most are not. For example, the statement "few puppies are cute" can be translated to "some puppies are cute but most are not".
So, in order to negate that statement, we would say "most puppies are cute but some are not". Hope that helps!
To add on to my confusion for this passage, #20 completely threw me off as well! I eliminated D because how do can we know that other neurotrophic factors perform other functions that are not specified in the passage? From what I can tell, the passage only states that there are other neurotrophic factors that promote cell-growth (which is why they are classified as cell growth factors) which is why I chose E: The effects LM noted in her experiment (which was cell growth) are also caused by other neurotrophic factors not mentioned in the passage (see line 40-41). Help!
For number 16, isn't it a stretch to say that NGF is a process that "governs the development of the nervous system"? That's why I eliminated A in the first place. It seems to me like Levi-Montalcini's discovery of a SPECIFIC substance that is used to stimulate nerve growth would be more accurate and noteworthy. Can someone help me with my error in reasoning here!?
Yes but the question is asking for the author's attitude towards the fallacy, not his interpretation of what the Whig Fallacy is. By choosing E, you would be saying that the author completely (unqualified) supported the Whig Fallacy. Hope that makes sense!
For question 18, I ended up picking A because I thought gravity was two objects exerting force on one another. So, I thought it made sense that, an object without mass (which therefore cannot exert gravitational force) cannot induce other matter to exert gravitational force on it. In other words, without mass/gravity, another object cannot exert gravitational force on it.
I had trouble equating "giving a computer to all the children in Olga's family" as a negation of "worth more than expected/customary". Using JY's amazing LOTR example, what if Bilbo somehow stumbled upon all 19 rings of power and gave them all to hobbits in the shire for no reason. Just because he gave the same thing to everybody doesn't mean that its not more than expected/customary. Can someone clarify where my reasoning is wrong here?
For answer choice C, couldn't the phrase "outside of their workplaces" refer to the work places of other people? In other words, if I am not allowed to smoke in the McDonalds that I work in, aren't I being protected from secondhand smoke in a Burger King (outside of my workplace) because those that work there can't smoke there? In this case, the law is offering me protection from secondhand smoke by prohibiting others from smoking in their respective workplaces right? So doesn't the stimulus allow us to reject answer choice C given my above example?
