PT2.S2.Q15 - a well-known sports figure

Please help. I don't understand why (C) is wrong.

Stimulus: No combining publicity appearance and competition. So it is "not both" rule.

PA-->/Competition, or it could be Competition -->/PA

PA-->/Competition

Competition

_________________

/PA

(C)

Tomato thrive --> Hot Summer

/Hot Summer

______________________

/Tomato thrive

I was also having trouble subtle differences of serious emergency and critical emergency.

(B)

less serious emergency -->/critical emergency

fairly minor emergency

____________________

/critical emergency

I would think fairly minor emergency would also be non critical emergency....

In (B), why does it must reflect facts about the interpreter? Couldn't it only reflect his philosophy, opinion, beliefs, or his view of the world and we still know more about the critic than the writer, not necessarily facts? It wouldn't be appropriate to call his philosophy and opinion "facts about him". I don't see why B is absolutely necessary.

I thought, if they can store oxygen directly in their muscle tissue, it could strengthen that they can store oxygen in their spleen. After all, it's storing oxygen somewhere in the body besides lungs.

If (A) supports it because some distant mammal does it too, then for the similar reason, (B) supports it too...

Any thoughts on this?

Helpful to identify with those labels. Thank you.

According to the stimulus, the club president has disallowed Jeffrey to vote. Thomas is arguing that that was in violation of club rules.

(Structure)

Premise 1: Rule: Vote --> Good standing member

Premise 2: Jeffrey is a good standing member

Conclusion: The president’s action of disallowing Jeffrey to vote was in violation of club rules.

Here are club rules: only good standing members may vote. (vote—> good standing member)

Jeffrey paid his dues on time and therefore he is a good standing member. Necessary condition is satisfied, therefore we don’t know if he is allowed to vote or not allowed to vote. There could be other criteria to qualify to vote that Jeffrey does not meet, in which case he is not allowed to vote. Or Jeffrey meets all the criteria to vote, in which case he is allowed to vote. We have no information about it.

But, Thomas concludes that the president’s action of disallowing Jeffrey to vote was in violation of club rules. Disallowing Jeff's vote could or could not be in violation of the rules. In spite of this possibility that it may not be in violation, Thomas made a determination that it is in violation. This is the flaw. He is saying that allowing him to vote is in compliance with (authorized by) the rule. (In other words, to be in compliance, Jeffrey should be allowed to vote.)

And that is what answer choice (A) is saying. His argument fails to take into account the distinction between something not being prohibited (allowing Jeffrey to vote) and its being authorized (in compliance with the rule). He is saying that allowing to vote is in compliance with (authorized by) the rule. At the end of the answer choice A, words “by the rule” is omitted. “Authorized” here does not mean his being authorized to vote, but rather, it means being authorized by the rule.

We can also view it as sufficient condition, necessary condition confusion flaw. Because in reaching the conclusion, Thomas mistakenly assumed the club rule as: good standing member —> vote. But this is not in any of the answer choices.

(A) is the correct answer.

(B) There is no character attack here.

(C) There is no such statement being denied or regarded as true here.

(D) What they were voting about is irrelevant.

(E) Whether Althea is authority in club rules or not is irrelevant.

Answer choice (A) was written very tricky that it was difficult to recognize it was the right answer.

PT5.S3.Q06 - whale's skeleton

I had a hard time understanding why (A) is the right answer. After thinking about it for a day on and off, I came up with this reasoning. Please take a look if my logic behind getting the right answer is correct.

I wonder if this this question can be viewed as Resolve Reconcile type; the premise says the land-dwelling whales needed hind limbs capable of supporting its weight, and conclusion says the fragile limbs of whale found in the fossil is the remnant of whale once lived on land. But I tried to solve it as strengthen question.

This question talks about whales from three different periods; ancient whale (lived before fossilized whale skeleton), fossilized whale, and modern whale.

Premise:

  • Whales once must have needed hind limbs capable of supporting the weight on land.
  • Evolved whales now have only bare remnants of pelvis. (The implication is that it had a more substantial pelvis before)
  • Fossilized whale skeleton had only a partial pelvis and very fragile hind limbs not enough to support its weight.
  • Conclusion: The fragile hind limbs are remnants of limbs that land-dwelling whale once had.

    I initially misunderstood the conclusion as the fragile hind limbs found in the fossil is the remains the whale that was living on land. So land-dwelling whale having fragile limbs is contradiction within the premise... but the correct understanding is the fragile hind limbs newly found in fossil is how the ancient whale evolved to be. The key was a correct understanding of the word "remnant."

    So, to summarize it... whale evolution is like this chronologically.

    Ancient Whale (ones lived before the newly found fossilized skeleton)

  • pelvis? Premise doesn't say it yet.
  • had strong hind limbs enough to support its weight on land
  • Fossilized Whale

  • had partial pelvis
  • had fragile hind limbs not capable of supporting its weight on land
  • Modern Whale

  • has only bare remnants of pelvis
  • So, we need to strengthen the conclusion that the fossilized whale skeleton that has fragile limbs is the evolved form of whales limbs that lived on land at one point.

    (A) is correct. The confirmation that ancient whale had a full pelvis would strengthen that by evolution it became a partial pelvis (as found in fossil) and now only bare remnant of pelvis.

    (B) This weakens the conclusion

    (C) irrelevant

    (D) I initially chose this answer and that was because I misunderstood what the conclusion meant precisely.

    (E) irrelevant.

    It became a quite long explanation... I wonder if I am overthinking when it is really a simple question. I would appreciate any confirmation or correction on my reasoning. Thanks!!

    The stimulus says, avoiding dairy leads to less likelihood of fat intake which then leads to less likelihood of heart disease.

    Avoid dairy -- less fat -- less heart disease

    However, it concludes that avoiding dairy will lead to increased chance of good health.

    We only know that avoiding dairy would lead to less heart disease, not necessarily to good health. The argument makes an assumption that less heart disease is equal to good health. In other wards, the argument neglects the possibility that avoiding dairy could lead to something other than good health.

    (A) says that. The argument ignores the possibility that . . . it's elimination (dairy) may also have negative consequences.

    Flaw in the stimulus: There are other possibilities besides the conclusion author arrives at. The tickets could have been issued to professors, parents, other visitors during the school year or cops enforce more strict during the school year. The flaw is that the conclusion is not valid.

    (A) This looks similar at first, but the flaw type is different. As children moviegoers increased, popcorn sale increased. It concludes that children buy most of the snacks. This is flawed because it concludes whole (snacks) from a part (popcorn).

    (B) I don't see any relationship of the plant being greener and getting more sunlight.

    (C) Study and studious is not the same. One can study little but not be studious person in general.

    (D) This could look similar, but misses the flaw of the stimulus.

    (E) The snacks could have been given to other parents or friends, not necessarily to other people's children. The conclusion is not valid because it neglects the possibility that the snacks could have been given to other people, not necessarily to other people's children.

    I am having trouble understanding why A is the right answer.

    P: Ink from Bible by Gutenberg contains titanium. Ink of another bible from 15th Century contains titanium. Ink from other printing from 15th century does not contain titanium. (from the word "another" I am thinking that Gutenberg Bible was from 15th Century)

    Conclusion: This finding supports (1) B3 bible was printed by Gutenberg, (2) We cannot doubt that the Vinland Map is not from 15th century because of the presence of titanium in the ink.

    In arriving the first conclusion, the author is making an assumption that only Gutenberg used ink containing titanium in 15th century.

    What I don't understand it that in arriving second conclusion, I don't see that the author is making an assumption that ink containing titanium was widely used (not restricted as the answer choice A states). I am thinking that it could be that those Vinland Maps were printed by Gutenberg. In that case, the second conclusion follows well. The second conclusion is based on the premise that ink containing titanium was used in 15th century by somebody. How can we say that the author is assuming that titanium ink was widely used (not restricted) from this conclusion? The premise is talking about one Vinland Map in question and we don't know how popular that map was during that time. It could be there were only few copies made by Gutenberg, then can't we conclude that presence of titanium in the ink of Vinland Map is no longer a reason to doubt of 15th century authenticity?

    Thank you for any help you can give.

    @ Thank you for fixing it! It is much better.

    If I may suggest few improvements...his could be a minor issue, but if you get to it, it would be helpful: when scrolling up and down, now although it does not leave the highlights, it temporarily highlights the whole line and it could be distracting when taking the timed PT.

    Also, at the beginning of the PT, it would be great to have little bit of time to adjust font size, view format, spacing, etc.. before the clock starts to tick.

    Thank you so much for developing this. It is really helpful!!

    When you apply, schools usually email you for an Application Status Checker user ID and a password, which is usually in the receipt confirmation email. Have you received it? If not, you should probably call them.

    I am admitted to a law school with a scholarship. The tuition deposit is due 4/15/2020. I am considering to retake the LSAT again for a better score for a more scholarship consideration. The earliest I can re-take is the March Exam (3/30/2020) but the score will not be released until after the tuition deposit deadline. If I get a better score after making the tuition deposit, will the school still consider giving more scholarship?

    I am using iPad (6th Generation) and I have trouble with highlighting. When trying to highlight using Apple Pencil, it grabs the entire passage and drags the entire passage to the direction the pencil is moving and does not highlight, when it does, it highlights large chunk of the passage.

    http://classic.7sage.com/lsat_explanations/lsat-23-section-3-question-06/

    I had some reservations in choosing answer choice C. I was able to eliminate all the others so answer choice C seemed most likely to be correct, but I wasn't 100% sure. The reason is that the premise states "The purse of a trader in the city "would probably" have contained a more diverse set of coins." and the C uses more definitive word, "had been brought". I think we don't know for a fact that it 'had been' brought by the pilgrims. It is a speculation. Since it is only a speculation that the purse would probably have contained a more diverse set of coins. I would think the correct answer would say "The purse... was probably brought . . . by a pilgrim."

    LG with truck on east west north south, is it real? It was the Section 3. The second LG for me.

    I had LG LR LG RC LR.

    RC had DuBois and Washington, Copyright, Beetle, Justified lying (not in order).

    This is a really unusual question and took a long time to come up with this reasoning. Any feedback on my reasoning would be appreciated.

    Context: There is a new law which will take effect soon and gives the patients legal rights to see their medical records. Doctor’s opines as the following:

    Doctor’s Conclusion: patients should not have a legal right to see their medical records.

    Reason 1: it will significantly reduce the amount of time that staff can spend on more important duties thus it is time wasting.

    Reason 2: No patients will ask for it anyway, based on his experience so far.

    Now, reason 1 is not even necessary to mention because reason 2 cancels out; if no patient will ask for it, whether it takes time to retrieve and return files doesn’t matter. They will not be time spent on that task anyway. Now the task is to find one answer choice that will make reason 2 not cancel out the reason 1. In other words, find a scenario in which even if no one asks for the files, it will still be a waste of time as a result of the new law.

    (A) Correct. If the new law will require the doctors to be ready to produce records immediately each time they see patients, then reason 1 matters, even if no one asks for it. So with this new law, the reason 2 does not cancel out reason 1.

    (B) Wrong. Even if the task of retrieving and returning files fall to the lowest-paid member of the office, if no one will be asking for it, it doesn’t matter how much time it takes to handle the files. Reason 1 is cancelled out by reason 2.

    (C) Wrong. Even if this is true that patients will require more time for explanation of their records, reason 1 is still not a good reason if no one will ask for the records. Thus reason 1 is cancelled out by reason 2.

    (D) Wrong. If they can get extra payment for the staff to handle the records, it will not be a waste of time so in this scenario, reason 1 is cancelled out even more so.

    (E) Wrong. This is no different from what stimulus suggests. If no one asks for the records, reason 1 doesn’t matter. Reason 1 is cancelled out by reason 2.

    PT1.S3.Q4 - Military Deterrence Psychology

    I understand why A, B, C and E are wrong, but I am not quite convinced that D is the right answer either.

    I would think that if a nation that seeks deterrence and has unsurpassed military power as stated in (D), it would not be the interest of that nation to let the potential aggressors become aware of its actual power of retaliatory attack which is not that great (since they have unsurpassed military power). They would rather want to make the aggressors not know of their actual unsurpassed retaliatory power but make the aggressors believe they have higher capacity than their actual military power, so that the aggressors would believe it could not defend itself against that retaliation.

    Yes, your reasoning seem to be good.

    Premise: Oct. & Nov. 1929 suicide number was comparatively low.

    When market was flourishing in summer, suicide number was higher.

    Conclusion: "suicide wave" after stock market crash of Oct. 1029 is just a legend, not fact.

    Weaken: we need to support stock market was indeed the cause of suicide wave.

    So we need to show, (1) when there was cause, there was effect or (2) when there was no cause, there was no effect.

    Answer choice (C) does (1). In Oct. & Nov.1929 (cause present), suicide rate was higher than those months of other years. (effect occured)

    This is a weaken problem, but the task is to strengthen the causal relationship.

    As a side note, to strengthen causal relationship: prove that

    when cause present - effect occurs, or

    when no cause - no effect occurs.

    To weaken causal relationship: prove that

    cause present - no effect, or

    no cause - effect occurs.

    B: Deforestration continues at its present pace --> koala approach extinction

    P: Stop deforestration --> Koala saved

    If you look at this sentence, "All that is needed to save the koala to stop deforestration," it's saying that if you stop deforestration, it is guaranteed that koala would be saved. So stop deforestration is sufficient condition.

    (B) is consistent with Biologist. Deforestration being stopped is failing sufficient condition of Biologist, so koala could approaching extinction or not approach extinction. Both are possible. (sufficient fails, rule becomes irrelevant) so deforestration stopped and koala becomes extinct is consistent with biologist's statement.

    However, It's inconsistent with the politician. If deforestration is stopped, koala must be saved, but (B) says koals becomes extinct, which is not possible. (sufficient condition satisfied, necessary condition must follow) That cannot be true and is inconsistent with politician's statement.

    If you think of "consistent with" as could be true, and "inconsistent with" as cannot be true, it may be little easier. So find a scenario that could be true with biologist's statement, and cannot be true with politician's statement.

    To solve this problem quickly, you can just look at what cannot be true with politician's statement first. If there are more than one, then narrow down to something that could be true with biologist's statement, but in this case, there is only one. So find the one that satisfies politician's sufficient condition and fails the necessary condition: stop deforestration, koala become extinct.

    Confirm action

    Are you sure?
