PT16.S2.Q24 - uplandian supreme court

Can someone give me some feed back on this? The reasoning denies a conclusion in order to show a premise is false. Is that an acceptable method of argumentation? I know that conditionally, if A->B, then negation B = negation A, but does that hold true in this argument? Namely, the argument intends to show that the premise in sentence 1 is false by showing that the conclusion it supports in sentence 2 is false. Is that a valid form of argumentation? Would really appreciate some help on this point; i will clarify if my description is not descriptive enough.

When i was doing this question, i was thinking "JY is definitely going to mention Dramamine and/or the stretching-jogging question from preptest 64 section 1 question 13 when he explains this video".

New PT's JY has updated

For those who haven't noticed, JY recently finished putting up video explanations for every question of preptests 36-45 (previously, some of them had some missing), so if you were having trouble with any of those questions, check them out.

Big thanks to JY. All hail the king.

It's not a licensed LSAT test question. Its a game manufactured by a test prep company, so you'd probably be best to stay away and stick to the licensed questions.

Really helpful explanation. When I was doing this question I was thinking about whether the argument intended the reader to accept the (flawed) argument that constitutes the argument for the intermediate conclusion. This is something that's definitely rare, but I was actually thinking about a different question while doing this problem. PT65 S4 Q26 is very similar in that an intermediate conclusion is established through faulty logic (a blatant whole to part flaw), and whose conclusion is used a premise to support the argument's main conclusion. Definitely something you don't see every now and then. Thanks again!

Word of advice: Only read the explanations by users with the title "LSAT Geek" in their profile. The others are just by students and probably aren't as helpful.

Stimulus:

Labyrinth display ➞ Well Crafted (WC)

Labyrinth display←s→ halogen lamps (HL)

Conclusion: (HL) ←s→ (WC)

If you're unclear on why that conclusion follows logically, review your lessons.

Answer choice D:

Lakes←s→Minnows

Lakes → Teeming with healthy fish

Conclusion: Minnows ←s→Healthy

Not the same thing; in fact, it is a flawed argument. Teeming with healthy fish isn't equivalent to the idea that every fish in the lake is healthy. We would need the argument to say that ALL the fish in the lake are healthy.

I wish they'd used a fish that was a little more obviously a fish. Like salmon. I didn't really know what a minnow was but needed to assume it was a type of fish.

Great advice, Chrijani. Memorizing them without understanding them will also cripple you if a harder question really requires you to understand what's going on in terms of the logic involved.

Hey Quick Silver,

Your analysis is correct and your allegedly inappropriate 'real world logic' is actually quite LSAT-esque and pertinent to this problem (i completely disagree with the above comment, and you should too. No offense intended though, just speaking for the sake of our LSAT knowledge). JY actually alludes to your reasoning while pointing out something else you may not have noticed. At minute 2:00, he says that the sample is likely to be unrepresentative because the respondents are from a group of people who already own it, and ON TOP OF THAT (he says this) they are unlikely to be representative (alluding to the respondent discrepancy you pointed out). However, while alluding to your absolutely valid explanation of the answer choice, JY seems to prefer the respondent/non respondent discrepancy as the main thrust of his video's explanation.

It is definitely the case that this argument fails to account for the possibility of sample bias; namely, that these businesses were already in a position that made these systems better for their particular businesses. To use your scenario, perhaps the GPS owners like them because people who love GPS's refuse to purchase cell phones. There are a host of reasons why the group of video conference system owners are unlikely to be representative of businesses in general.

I actually agree that it may not be the case that the LSAT was intending readers to identify the respondent/non-respondent discrepancy. I've never seen a flaw question using samples that are flawed because of the respondent/non-respondent discrepancy, but i actually think it may be something we're supposed to keep in mind.

If you take a look at the June 2007 LSAT, look at question 15 of the 2nd LR section. One of the answer choices (that actually turns out to be incorrect) raises the possibility of a respondent/non-respondent discrepancy possibly weakening the argument. From that answer choice, it does seem like the LSAT writers may indeed be thinking about this. It seems like the LSAT defines a survey as something that participating in is optional, so it would be wise to actually keep this in mind. Maybe that's a bit of a stretch. What do you think?

Assessing passage difficulty without reading and answering the questions is not possible, period. Even if a brief glance reveals it is a science passage which may have you thinking you'll flunk it, that is not necessarily the case. Nor is question quantity a reliable indicator of difficulty, as some of them may be extremely easy. Nor are comparative passages definitively more difficult, as some of their difficulty levels have paled in comparison to other passages in the same set (mirrors, anybody?) There is no strategy through which you can infer an optimal order through which to approach the passages, period. Do them in order, and do them right.

Technical Problem on Preptest Answers

Anyone else notice that the question whose video explanation you are viewing is no longer highlighted in the question numbers on the answer page for preptests? Makes it kind of annoying to go through question by question when doing your review of the preptest and you want to go question by question but don't necessarily remember the specific number of the question you are on. I know it still says the question number on the top of the page but it still is kind of annoying.

I think JY has cursed in videos about two to three times at max. And your argument presumes both a specific definition of professionalism and also that its presence is inappropriate to an audience of college students.

Here's my favorite moment.

For those who have taken the test, you may recall a sticker that seals the test book itself. Typically, the proctor instructs you to remove this seal as part of the lengthy directions that precede the actual taking of the exam. Ample time is traditionally given during the period before testing actually begins (numerous friends have corroborated this for me) to make sure each student removes this sticker (it is likely there to prevent one from surreptitiously opening the test booklet during the period in which you write in your information).

My administration was different. After asking whether we had any questions, the proctor immediately said "begin", forgetting to instruct us to remove this protective sealing. Having had no time to remove this sticker, and having just cut my nails the night before, i found myself unable to quickly remove the sticker with my nails. I decided to furiously rip the front page off in an attempt to hasten this process, but ended up ripping the whole front page of my test booklet off. It was a nightmare; i expected to be swarmed by proctors who suspected me of cheating. But to my surprise, the same problem had plagued my peers (none of whom ripped off the front page of the book, however!).

I was allowed 15 seconds of extra time and my book was replaced. I scored in the 99th percentile and was admitted to a top school (thanks to 7sage, of course) but it made me quite jittery and nervous during the exam itself. So the moral of the story: be prepared for anything. And keep one of your nails sharp for that sticker.

Good luck to all those studying for this year's exams!

There's a certain point where they won't let you in anymore so it doens't matter when it starts. Don't get there late. I think you need to be there at 830. The time the actual exam begins doesn't impact this. Don't make this mistake!

You're not just paying for the tests; you're paying for JY's explanation of the answers. He does every question in all of the videos for those exams and he also has videos of himself doing the LR from one of the exams, and RC from one of the exams, which i found immensely helpful (its him doing it in real time, having never seen the exams before). If you can't afford all of them, you should try buying at least one or two from 7sage (72 and 71 probably) and then buy the other two from amazon, if you are cash strapped.

The stimulus asserts that everyone acts in ways influenced by the way in which they were treated as infants. Everyone, including adults. We know infants have no control over their treatment and so in accordance with the stimulus are not responsible for the consequences of actions that result from that treatment. So if adults are acting in ways that are influenced by treatment as an infant - treatment they necessarily had no control over, in accordance with what the stimulus says - then adults must commit some actions for which they cannot be said to be responsible. Again, the stimulus said that EVERYONE acts in ways influenced by childhood treatment (treatment they had no control over because they were infants).

E says that it must be true that no adult can be responsible for every action they perform. Absolutely true. Because some of those actions are performed because of childhood treatment. The stimulus said every adult performs some acts that are a result of infant treatment. So every adult performs actions for which they cannot justifiably be assigned culpability. Hence, to say that no adult should be responsible for all their actions (some of which include these actions for which they are not responsible) would be correct.

Did you want formal logic in an explanation? That'd be a little tricky on this one but doable.

I think that if you study harder and do more PT's, there's room for improvement.

Don't blame the exams' curves though. Each exam's curve reflects a specific standard of difficulty; the exams are supposed to be equal in difficulty. So a -12 on one exam and a 14 on another merely reflects the way in which theyve accounted for potentially easier questions on one section. It is equally difficult to get a 170 on every exam. Thats how it works. Preptests 72 and 73 aren't and harder than the one's you've taken in the past.

I had an amazing experience with testmasters, i'm sorry the rest of you didn't. I don't believe TM's quality was superior to 7sage, but i appreciated having an expert clarify anything i was unclear about. I'd recommend getting feedback on a specific instructor if you elect to take a TM course, as my guy was stellar (he scored a 180, although that isn't necessarily indicative that a tutor will be good.)

Absolutely BR reading comp.

If your scores aren't where you want them to be, postpone. You'll improve with time, but 13 - or even 8 - points of improvement from preptest scoring in less than 20 days is too much to reasonably expect. You don't need anyone on the forums to tell you that.

Hey guys,

At the beginning of JY's RC passage readings and logic game videos, he always says "this should take you X amount of minutes". Do you guys generally look at his time recommendations and use them as guidelines for when you do the test? For the games, understandably its important to know how long it should take you when you're reviewing them and getting faster at forcing out inferences and finishing the game. But what about for reading comp? I have about 24 fresh tests left (for the February LSAT) so i'm debating whether i should start doing that.

Confirm action

Are you sure?
