PT9.S2.Q17 - Certain instruments

Since there is no video explanation for this question, I would appreciate it if someone could confirm my understanding below.

It took me so much time to figure out what the second sentence is saying :(

Second sentence

energy used to sterilize of a set of nylon instruments: SN

energy used to manufacture of a set of nylon instruments: MN

50 x SN = 3.4 x MN

SN = (3.4/50)MN

SN = 0.068 x MN

energy used to sterilize of a set of stainless steel instruments: SS

energy used to manufacture of a set of stainless steel instruments: MS

50 x SS = 2.1 x MS

SS = (2.1/50)MS

SS = 0.042 x MS

Answer choice

(B) is the correct answer (MBF) because SN has to be less than MN. SN = 0.068MN

(A), (C) - (E) could all be true.

For the RC section, would you advise to start timed like J.Y.s version or not timed and then after getting a handle of structure then start timing like J.Y.s? Thank you so much!!!!

Anyone else experience a RC drop after the CC? My first diagnostic I took back in November had me at missing 7 questions in the RC. I've consistently scored missing 5-7 on each RC for entirety of my LSAT studying. Honestly, I haven't really bothered to beef up my RC score because I was doing okay without studying for it, and so I focused on the LR and LG. Usually the incorrect questions are from the last passage when I'm feeling a little rushed. SO I decided to go over the 7Sage CC for the RC to help me eliminate those 5-7 wrong RC questions. Now, after doing the 7Sage CC for the RC my score has COMPLETELY dropped. Like, -14 for RC instead of the usual 5-7 wrong. Anyone else experience this, and how did you undo the damage?

I asked about what types of questions rely on the understanding of sufficient and necessary conditions the other day. I got a lot of really good answers. The issue I am having, and have continued to have throughout my studies, is that they don't stand out to me. I spent a lot of time learning the indicators, making flash cards to remember how to employ them and I have it down by heart. When I'm in the LR section however, I am so hyper sensitive to these words I pick them all out. I have yet to find a situation where I have seen a question, realized it is dependent on my understanding of suff/nec and applied my knowledge to it. Is there a method to identifying when mapping X -> Y on a question? What am I missing?

In LG it is extremely clear and I have no issues.

What strategies work best for you? How many passages do you attempt in practice tests? What have you found helps in increasing your score?

Thank you so much in advance!

Hello All,

I have definitely improved in mapping out my LG games and making inferences and other actions involved in tackling LG games. But when I take practice tests, I seem to be lost at the outset (maybe feeling pressured because of time) and take alot of time to determine what strategy to employ (linear, in/out,grouping etc...) When I come back to the question to blind review it after watching the help videos, the question becomes way more easy than when I try to tackle it under timed conditions.

Is there any fast way or are there any immediate rules to determine which strategy is best to use to tackle a game?

I've studied the valid/invalid arguments and though it's almost down, I sometimes still have mix-ups. I'm wondering if it's a good steadfast rule that, most and some only allow you to draw valid inferences if they occur first, then all the relationships following are "all" relationships?

ex. A some B ---> C

Is this a rule that works every time? If so, are there any other simplified one liners to help internalize?

Thanks all!

I thought that this was an example of a part to whole fallacy. The author concludes that the decrease in revenue is exaggerated because part (parts and service companies) of the industry have succeeded even after admitting that manufacturers' share of the industry's revenue has fallen. Does (B) address this flaw?

Hi 7sagers,

I just recently solved the question referenced above, a MBT question with heavy conditional reasoning. I understand why TCR is what it is, but it took me WAY too long to solve this question. Even in hindsight/BR, I don't know how I could get through a question like this in 1:25.

I ordinarily feel comfortable with conditional reasoning - I can picture contrapositives mentally, can twist around unless statements without diagramming, solve some conditional stimuli without diagramming (though generally they don't have a ton of sufficient conditions), etc. Even some of conditional-heavy stimuli that have several statements/premises tend to link up in a linear fashion and can be pictured without diagramming.

I think that what threw me off in this question is that between the two conditionals in the stimulus, there are just a million sufficient conditions to keep track of!

Do you guys have any tips/shortcuts for cutting through a question like this relatively quickly?

TIA!

Could someone help me shed some light on why the correct answer is correct? The passage refers to "such protection", as protection for the sellers (to not have to sell to a buyer who bids extremely low), but the correct answer (E), doesn't seem to be related to that at all. A bit confused.

Any word on when the explanations for PT80 will be released?

I am having a hard time understanding this section of the lesson and am hoping some folks can weigh in on it. I think I'm a bit lost because there is little context on when I would be using these tools and how. Also, I am unsure exactly what to memorize. Should I be memorizing both the valid and invalid diagrams and be prepared to use them in future lessons? Also could someone explain exactly which types of questions these will be useful for? Thanks in advance. :)

Does anyone have any strategies for answering parallel reasoning/flaw questions more quickly? These questions consistently take, in my opinion, far more time than they should for me.

My method has been:

Does anyone else have any useful strategies?

The main issue for me seems to be how time consuming these questions can be. In the explanation videos, there is the luxury of answering a question in 8 or more minutes, but on the exam this amount of time is obviously not feasible.

Thanks!

Hey 7Sagers,

I've been studying for at least a year now But for some reason I have so much trouble trying to correctly answer Assumption, Sufficient Assumption and Necessary Assumption questions. I have gone over the curriculum and been utilizing negation tests, conditional logic, etc. But I am simply not improving. Does anyone have a certain method that works for them? Or am I doomed? :/ I have been scoring 16 questions on LR sections but that would be higher if I got more Assumption questions correct. Any thoughts?

Admin edit: Please don't yell! The admins scare easily. (Caps from title removed.)

I've noticed that some of the LGs in the most recent PTs don't fall into the strict sequencing/grouping/grouping and sequencing categories. In several places on 7sage, users note that they found games from earlier PTs helpful in practicing for these nontraditional games. Can anyone recommend specific games from specific tests to practice?

thanks!

Hey everyone, I'm just posting here to see what people might think of my decision to postpone taking the LSAT until September. My goal is to test 170. My average is in the mid 160s but the only tests I've been able to score in the 170s have been retakes. Fresh tests are all in the 160s. :( I don't want to postpone because I feel emotionally ready but I think it's the wisest thing to do. The most annoying thing is how expensive it is!! And $100 to postpone vs 180 to just sign up again. I know that's not nothing but... fricken LSAC. Anyway, what do people think? To postpone or not to postpone?

Also, this is a related question to getting out of 160s plateau. I've seen on here that top scorers get through LR with like 10 minutes to spare. That's never happened to me and I'm not sure if my goal should be to just "work faster" (a mentality that, when I adopt, just makes me rush and be careless) or if I should continue to be cautious, to utilize POE unless I'm almost 100% sure of an answer, to give myself two read throughs if I don't understand a stimulus right off the bat as opposed to immediately skipping. Is there merit to a 'slow and steady wins the race' type of approach for top scorers in LR?

Did anyone take it after they'd seen major improvements (my diagnostic was a 153) but not quite reached their max? Any thoughts on LR strategy would also be appreciated.

Good luck to those who know they're ready for June! Jealous!

I am so confused by the video explanation on this one. At 1:27 the video says that an answer choice is "totally compatible to the statement above because they have nothing to do with each other"

===> WHAT??? Compatibility is not having anything to do with a subject? I can use some guidance. Thanks.

https://classic.7sage.com/lsat_explanations/lsat-38-section-4-question-25/

So I'm working on these question types and have found a pattern. When it is a Causation strengthen question, the answer choice becomes apparent very quickly to me. I am able to identify it, and explain why the rest are wrong with a decent amount of ease. Once the question stem changes to weaken however, I no longer can see the answer and missed all of them. J.Y. said in his explanation that these two types of questions are really the same when it comes down to identifying the answer choice. So what am I doing wrong?

Hello gamers,

I seem to always get stuck on sequencing games where one of the rules involves having "at least two spaces between X and Y". I get particularly stuck when there's a switch on top so it can either be X _ _ Y or Y _ _ X. Furthermore, sometimes I skip over the "at least" part, which ensures other issues... I know this uses the same concepts as all other games, but for some reason this kind of rule always takes me longer to get my head around. Does anyone else have this issue?

As for improving time, anyone know of certain games with this quality? I want to do as many as possible so I can get more comfortable.

Thanks!

Hi Everyone,

Last session was great. Thanks to everyone who showed up. We made RC fun!. : )

So last time we focused on low resolution-high resolution summary and how to read and comprehend RC passages effectively. This time, in addition to practicing this method, we are going to do one A-B passage. There is a different way to do such passages which makes these kinds of passages a piece of cake and I think it would be helpful to show and practice this method.

Since A-B passages don't start till later PT's, we would be practicing on one of the recent tests, PT 65. But I think even if some of you havn't done any of the recent PT's, it would be helpful to use one of them to understand how to do these kind of passages. There are 86 PT's to practice, using one for learning LSAT will be a good call.

If any one of you does not want to Burn PT 65, you are welcome to take it on your own. But lets Blind Review Passage 3 together.

If you do not have time to take it, that's fine as well. We will go over the passage together.

Let me know what you guys think.

P.S. Does this time work better for some of you who couldn't make it last time?

People who have done a lot of PTs often talk about the shift in language in the last 10 PTs, yet don't always know how to articulate what that shift specifically was. I think this is an example of a recent test question where the language has changed as compared to older tests (PTs 20-60).

I think the correct answer, E, requires you infer the author's perspective whereas older tests would have a more conservative interpretation of the stimulus. By saying that juries often make serious mistakes, you have to infer that the author would say making a serious mistake is an undesirable consequence.

In these LR questions where the stimulus has an opinion, it seems as though the test now tests your understanding of that opinion. That if someone is saying something would be a serious mistake, you need to be able to properly infer what that means. In this case, someone who says it would be a serious mistake then that person would also necessarily say that's an undesirable consequence.

I'm not sure exactly when it opened up, but I just wanted to let all those wondering about when September's registration would open up that it's allowing registration now! Good luck, everyone!

Doing a quick review of concepts that I struggled with early on.

I remember the following rule being simple to diagram:

L is before M but after K.

K-L-M

But I also remember that there is another type of rule that is similar to the above but it involves and "or". I think it goes like this:

K is before M or after L, but not both.

M-K-L, or L-K-M?

Does anyone know what I am referring to? If so, could you link to the lesson or a game that highlights the above?

I can't remember where it came from but the difference between the two above really stumped me at some point....

I've heard a lot of people recommend the Manhattan RC book to supplement your RC curriculum. Has anyone gone through the Blueprint RC book? I already have a copy of that laying around so it would be easy to go through it, but I am curious if it would be more beneficial to skip it and go straight to Manhattan's book instead.

Any feedback is welcome. FWIW, I definitely struggle the most on RC. I just want to make sure I spend my time learning it in the most efficient manor, and not having to test 3/4 different methods before finding one that sticks.

I also plan on using @TheoryandPractice 's RC summary s/he posted a few days back; I just would like to get a better baseline before jumping into the application of their methodology.

I got -9 on one section and I was wondering what advice or steps anyone has to reduce that number? I am keeping the main point in mind in each passage and relating the passages to each other but I still got 9 wrong. Thank you so much in advance!
