I think a better explanation why E is incorrect is that we cannot be sure that there is a drop in domoic acid! Basically, E) says that P.australis' survival requires significant amounts of domoic acid P.australis survive --> significant q domoic acid along with numerous other compounds Just becau...

D works because it links up the "raw food" portion of the evidence to the conclusion about how cooking probably caused humans to be able to support a large brain (by getting more calories from less food). It ties in the second piece of evidence to the calorie portion by showing how cooked ...

Im not an instructor, but I can definitely help you with this one! The stimulus here is basically trying to equate the example of a promise to be an obligation. If somebody made a promise to meet somebody at a certain time and can't do so because of a traffic jam, the stimulus argues that this is eq...

This was an unusually difficult main point/conclusion question... I made the same mistake and chose D because I thought that was best supported by the stimulus. To me it made more sense that because retailers too often resorted to advertised price cuts to promote their wares, that leads to cut profi...

I chose B...why is B wrong? is it because it says there is no guarantee? I eliminated E because it says priority, but I did not see it discusses priority in the stimulus.... Thank you B) is incorrect because the stimulus already states that the first project is late anyway (read 2nd sentence). Ther...

(B) rests on further assumptions. How each splits in terms of favorable/unfavorable doesn't add support without more information. To get a bit more detailed, is B incorrect because even though S maybe "more likely" to give unfavorable reviews, we don't really know whether 50%+ of all his ...

Hi, I thought B is correct because if it's running longer, there would be more possibilities that GS has more errors. For example, If we write 1000 pages essay vs 1 page essay, there would be more errors in 1000 pages essay. I thought this is the similar situation... Why is B wrong and C correct? T...

For C to be correct, the author would have to say something like: "The act of donating blood does not imply altruism, because there is no reliable way to quantify, measure or see generosity." The counter evidence that we have though is that many people hesitate to admit to behavior that do...

Could somebody please explain why E is not correct? Premise 1: Females drawn to males with more orange Premise 2: Males tended to show females more orange during courting Conclusion: Male guppy will later courting patterns in response to feedback from female guppy I saw this as causal reasoning as i...

Is A also wrong because it does not apply it to a particular person? The argument is talking about Sharon; her beliefs and perceptions. A is not talking about a particular person changing beliefs and perceptions like answer choice D is doing. I think A is more wrong because we don't know if Sharon ...

Is it just me or was this question confusing? At first I was expecting to see an answer that would link the term "success" and the amount of trashing being "significantly lower." I can see how A eliminates a potential objection to the conclusion, but does it really matter what th...

Seriously, what exactly is the flaw with answer choice D? Its clearly flawed, but can't seem to articulate it well... It seems to do a mistaken negation on a limited group (20 year olds), but the necessary portion of the original conditional gets another characteristic flaw (equating becoming bald a...

I have a follow up question. I do understand that for parallel flaw questions, the argument doesn't necessarily need to have the same conclusion as the original stimulus. For instance if the stimulus has a recommendation, the correct answer choice need not have a similar recommendation. In this case...

I think what Ying is trying to say here is that the author is indeed assuming that the "most of the buildings at the site from the time period had limestone as their only sone component" is the same as "most were human dwellings" (or at least there is a significant overlap betwee...

I think there is a much more grave problem with answer B than just it not relating to the "best" of both VTAs and SSAs. This is answer simply talks about the "range of variation.". Do we know if this range is more towards the good sound quality end or the bad quality sound end? I...

Can somebody please explain why C isnt correct? I thought maybe if the number of trips went up, that would remove an alternative explanation for the reduction in fatalities (i.e., if the trips were indeed lower, then that may be the reason why child fatalities are lower). Same goes for the time spen...

Can we also reason that A is incorrect because of the word "programs"? The way I justified crossing this out was to think that even if the number of violent tv programs are low, one or two really popular violent programs maybe viewed by most if not all ppl. Hence the correlation may not be...

D seems a bit far of a reach because we have to assume that the diatoms died at the end of the last ice age. There is no indication of that fact in the stimulus. Typically wrong answer choices for weaken/strengthen questions have unwarranted conditional statements. I thought we can only mark these a...

I'd also add that for B, the answer choice only says that "typewriters have been superceded in most offices..." Now this means the scope of the answer choice is limited to most offices. What about the other places keyboards are used? (I.e., schools, homes, restaurants, etc.) If B said &quo...

Over the past year I know that some people have mentioned seeing grouping games with elements reused. I know this isn't a recent trend (many of the older games have multiple groups 3+ with each group getting at least one or up to 3 items). However, the game type I am referring to is your standard in...
