Passage 1 parallelism Computer
A p.1 huge tasks: calculation
p.2 PC can not handle
p.3 Internet connected PC parallel work; public support
B p.1 parallel everywhere; complex system
p.2 exe: ant
p.3 paradigm shift in computing

Q 5
I understand C is right
D: why is D wrong? passage B do mention complex system, and in ln 11-13, that's why there's no alternative for "brute force"

Q 6
D I am wondering why D is wrong? Is it because "most" large scale computing problem, which is barely mentioned in passage

Passage 3 Jap sculptor

p.1 ot: creativeness
p.2 previous work; started to be interested in positive light reflection
p.3 how he finds the suitable material
p.4 portrait of fuller
p.5 further pursuit

I am so confuse with paragraph 4, the relationship between pilot landing vs portrait of fuller, anybody kindly explain to me?
Q 20 Inference
E is obviously correct
C N's invisible sculpture appears to have no shape or dimension of its own--right
but rather those of surrounding objects--"distortion of familiar shapes in surrounding environment could be seen by viewers"---why this is wrong?
D oxidation--> change into realistic likeness no mention in passage
-----------------------------------------------------------------------------

Q21 Inference
B anybody please tell me B come from which part of passage?

Passage 4
Ultimatum Game

p.1 intro Ultimatum Game
p.2 continue give detail of UG, 2questions: why make fair offer? why reject low offer?
p.3 some theorist: prehistory ancestor group--not explain q2
p.4 emotion, evolution, distinction 1 time & multi-time
--------------------------------------------------------
Q 24 UG definition
A no "develop trust"
C I got this wrong, is it because it is too broad
-------------------------------------------------
Q26 complete final paragraph
I understand C's correctness
Why D is wrong by saying self-esteem has extra benefit?
-----------------------------------------------
Q 27 Logic strengthen paragraph 3---I have a major difficulty of this question
We suppose to find answer that prehistory uniform could explain why people reject low offer

B hierarchy about allocation and criteria of fairness
D It is just as counterproductive to a small social group to allow oneself to be outcompeted by one's rival (=why we reject lower offer?) as it is to outcompete those rivals(give fair offer?)
E based on equal distribution?

PT 59/Section 2/Question 22 Productivity & breakfast
I find this question particular difficulty though it features with a very LSAT stereotype. Here's my understanding
C and E both deals with equal starting points of A and B, which is irrelevant with "increasing" stuff
I am wondering B and D each seems talks about alternative factors about productivity: for B: two Plants' workers have the same workload "working the same time of day, no night shifts stuff etc), D: Plant A workers have a heavier workload by taking less vacation. Especially answer choice D mentions during the experiment month, A works harder than B, but achieving higher productivity, will it strengthen the argument by though more workload, breakfast did have a huge effect on productivity? Or it simply can be dismissed by assuming longer working hours resulting in productivity? Or to say A has been always having such a busy schedule, not a particular change in this month, in this sense no effect on the argument?

PT 59 S3 Q22 obligation, agreement
I have a difficulty to diagram this stimulus into A-->B formal logic, the factors look so similar to me, I am seeking help about this question, could anybody walk me through this one? Thx
---------------------------------------------------------------------------------------
That's all for my questions on PT 59. Thank you so much for reading such a long thread I posted. Any advice and suggestion would be very welcome and appreciated. :D

For the Noguchi passage (passage 3):

Q20: C is wrong because a positive-light sculpture doesn't appear to have the shape and dimensions of surrounding objects - the sculpture's own shape and dimensions are revealed because of the reflections of the objects in the sculpture. Lines 52-53: "the distortion of familiar shapes in the surrounding environment could be seen by the viewer. The viewer's awareness of the 'invisible' sculpture's presence and dimensional relationships would be derived on secondarily." So an object's reflection in the sculpture doesn't correspond to its own shape and dimensions, and the sculpture does appear to have its own shape and dimensions, making C wrong.

Q21: Lines 11-13 are the relevant part of the passage for answering this question. "By his early twenties, Noguchi's sculptures showed such exquisite comprehension of human anatomy and deft conceptual realization that..."

Passage 1 (comparative computer passages):

Q5: The "brute force" exploration mentioned in A doesn't necessarily entail parallel computing. Lines 12-15: "a 'brute force' exploration of all possible combinations ... This method requires very large numbers of calculations and simulation runs." The idea that parallel computing could accomplish a brute force exploration is introduced in the following paragraph. The similarity between Passage A and Passage B is the concept of parallel computing - the need for a brute force exploration is not necessarily connected to parallel computing, and thus not connected to Passage B. Thus, D is wrong.

Q6: Only Passage B says that there is a "great paradigm shift" (line 51) in the field of computing. Passage A says that parallel computing would be necessary to solve a certain type of problem, and that "some public resource computing projects" (line 27) had been successful. But the passage only states what should happen, and never says that any sort of widespread shift to this new kind of computing was occuring, either in most large-scale computing problems or in the particular computing problem discussed in the passage. Thus, D is wrong.

Passage 4 (Ultimatum Game):

Q26: The question stem asks us to "logically conclude the final paragraph of the passage." So we want a sentence that relates to a previous idea in the passage, but doesn't introduce any new ideas or further questions. So the "many other benefits as well" part of answer choice D introduce a new idea to be justified and explained, as these "other benefits" of self-esteem are not mentioned previously in the passage. Answer choice C is perfect, because it applies the final theory to the other group in the study, and introduces nothing new. The "may also help to explain" portion of the answer choice is a little wishy-washy for a firm conclusion sentence, but it's still satisfactory, and far better than the other choices.

Q27: The author's objection to the theory in paragraph 3 is that "this hypothesis at best explains why proposers offer large amounts, not why responders reject low offers" (lines 33-35). So we're looking for an answer choice that links this theory with the responders (aka one that weakens or nullifies the author's primary objection).
A - if hunter-gatherers lived in large groups, that further weakens the theorists' assertion, and we're looking for a strengthener. Out.
B - doesn't address the issue of competition. Out.
C - the idea of keeping secrets from a community is relevant to the theory in paragraph 4, not the theory in paragraph 3. Out.
D - those who have the potential to outcompete others are linked to the proposers (as the theory describes only those who choose not to outcompete others, and the author's objection is that the theory only discusses proposers); "allowing yourself to be outcompeted" would correspond to the responders, thus allowing the theory in the 3rd paragraph to be applicable to the responders.
E - the theory is about individual hunter-gatherers choosing to act for the collective good of the group. So this answer choice contradicts the theory,a nd would not induce the author to view the theory more favorably.

Section 2, Question 22:

I didn't exactly follow the specifics of your issues with this question, but I'll see if I can explain anyway.
The question stem asks us to strengthen the argument. So, when reading the argument, we look for a potential point of weakness. We are given that the productivity increased at Plan A. At the same time, plant A's workers received free nutritious breakfasts, while plant B's were not. The conclusion is that nutritious breakfasts lead to productivity. The increase in productivity is a given. However, the offer of free nutritious breakfasts or lack thereof is not the same thing as the workers actually eating, or not eating, a nutritious breakfast. We're looking for an answer choice that either confirms that Plant A's workers actually ate these breakfasts, and/or adds that Plant B's workers weren't eating such breakfasts on their own.
A- Exactly what we needed.
B - It doesn't matter whether they start work at the same time of day for the purposes of the study, only that they ate a nutritious breakfast. This factor alone increases productivity.
As you already pointed out, C and E are wrong because it's the increase we care about, not the absolute numbers or previous conditions.
D - Isn't relevant to the issue of breakfast. It might call into question the productivity as measured in the study - if workers took fewer vacation days at Plant A than Plant B, it could mean that they were more productive as a result of this. But we don't know whether this was an increase or decrease from vacation days last month, so it doesn't offer any conclusive evidence. And even if it were more strongly linked to the plant's productivity, it would only have the potential to weaken the argument, making it a doubly unsuitable answer choice.

Section 2, Question 22:

I had a tough time when I first saw this one also, partially because the correct answer switches around the order of the elements of the initial argument's pattern of reasoning. I'm not very well-versed in the structure and format of formal logic, but here's how I wrote it out for myself during the PT:

A = X
~Y -> ~X (contra: X -> Y)
Conc: A = Y

Crap. I put C for this today. Let me try to say why it's wrong and can someone confirm that my understanding is correct.
C says the invisible sculpture APPEARS to have NO shape or dimension of it's own, but rather the shape/dimension of surrounding objects.
THE PASSAGE says: has reflections of the surroundings (but doesn't take on their shapes/dimensions). Also, viewer gets an idea of the sculpture's dimension SECONDARILY (not that it appears NOT to have dimension, or that the viewer NEVER notices it).
Right? Thanks.

Yes, exactly! My explanation was kind of convoluted, yours is much clearer :)

I'll try.
Stimulus:
Makes an agreement --> obligation to fulfill
Obligated to do something --> agree to do it.

LEGAL obligation to do something --> required to fulfill one's agreement to perform that action

What is the flaw? making an agreement is SUFFICIENT to be obligated to fulfill it
But it treats it as if making an agreement is NECESSARY to be obligated.
( this is wrong because let's say you said "i agree to pay back my loans in 1 year , then yu are obligated to fulfill" but what if you didn't agree to anything..you might still have some obligations like "i feel obligated to help my struggling brother" -- this can happen even if you DIDNT AGREE TO HELP HIM IF HE WAS STRUGGLING)
Also there is a missing link because the argument links "obligation" and LEGAL obligation without giving any reason for linking them.

What makes the other answers wrong:

A) the stimulus doesn't mention "good consequences"
B) The argument actually seems to overlook the fact that there are obligations other than those resulting from agreements made
C) it doesn't say anything about which actions one should agree to
E) it doesn't mention anything about anyone being willing or unwilling to live up to their agreements.
