I chose answer choice (C) for this one. Suppose that only a few of the sites are responsible for the defective items. It's certainly a possibility that most of the samples collected could have been taken from these sites. That would mean that that 20 percent of the samples could have been defective,...

I got this question wrong on my first attempt. When reviewing, I came up with the following. Please let me know if I am on the right track. Thanks. drastic shift in climate --> migrations --> ideas necessary for rapid advances in civilization The contrapositive would state: ~ideas necessary fo...

Can someone go through all of the answer choices and rule out why (A) through (D) are incorrect? I guessed on this one. And even when I took the time to try to figure it out, choices (A) through (D) just confused me. Here's how I looked at it: Premise: approximately same age --> comfortable appro...

I agree with kimyooji and thought of it in the same way. Here's how I approached it... Premise: MAJORITY FAVORS --> AIRPORT BUILT Let's take the contrapositive of the premise so that we have it handy. AIRPORT NOT BUILT --> MAJORITY DOES NOT FAVOR Conclusion: Unlikely that majority will favor, ...

This year, a majority of Hollyville's residents responded to a flood in another town. This majority of Hollyville residents is a higher proportion of Hollyville residents than the proportion of Hollyville residents who responded to an earthquake a few years ago. Last year , Hollyville itself had a d...

Trade deficit does not weaken economy. So, there's no need to try to restrict imports to reduce trade deficit because, again, the trade deficit does not weaken the economy. We'd be doing something, restricting import, which will not weaken the economy. That's like putting a thermometer in cold water...

This is nasty. I was going between (C) and (E) and went with (E). I didn't even consider (D). Let me see if I can make sense of this in retrospect. lightest moths = greatest contrast = most likely to be eaten by predators So, it follows that... darkest moths = ______________ = least likely to be eat...

The argument really hinges on the following: The writings of Mayan religious scribes were mathematically very competent. Therefore Ancient Mayans in general had a solid grasp of sophisticated mathematical concepts. How can we make such a broad statement about Ancient Mayans in general just from anal...

Breaking down the stimulus... 1) Banks process zillions of transactions today. 2) But if your account is accidentally credited with a large sum of money, the bank will somehow, via its internal audit procedure, detect this error. Look at (A) and (D) a bit closer. (D) really isn't that strong. The ra...

I just did this problem like twenty minutes ago, so I'll give you my interpretation of why (A) is better than (B). Though, to be honest, I was really tempted by (C). Let's break down the stimulus... New technology that can extend life and decrease pain requires extensive scientific research. Investm...

No problem. Let's take a look. Rats in experiment 1 no adrenal gland + parathyroid gland -------------------- calcium decreases sharply Rats in experiment 2 no adrenal gland + no parathyroid gland -------------------- calcium decreases less sharply This means that the parathyroid gland is decreasin...

The question sets up two somewhat parallel situations: 1) Free-market principles are not violated when limitations are imposed on foreign investors/lenders to prevent the harm of economic collapse. 2) Free speech is not violated when limitations are imposed to prevent the harm that can occur as a re...

I narrowed this question down to choices (B) and (C). I incorrectly chose (B). Here's what I don't seem to understand about (C)... Deirdre does indeed shift the meaning of happiness throughout the course of the argument. "Many philosophers" describe happiness as fully living up to one's po...

Yes. Got it. Thanks for the clear explanation. Apologies for citing the wrong answer.

This one is troubling me. I chose (E) because it reinforces the idea that the larger houses were for the rich.

The correct answer is (C). Can we please go over this? Thanks.

Let me give it a shot before the experts chime in... Premise #1: The population of the driving age has increased over the past 5 years. Premise #2: The number of FATALITIES has declined. Conclusion: We have more skillful drivers than five years ago. Remember, we are judging the skill level of driver...

I narrowed this question down to choices (A) and (E). Choice (A): the businesses impacted by the recession can take advantage of lower rents outside the financial center. So, this makes sense. But, how are we to know that Goodbody will have those lower rents? What if other buildings have lower rents...

I originally put (D) also. Here's how I made the problem make sense to me... The question is asking you to assess the flaw in Oscar's reasoning. Oscar tells us that speed of information processing will be the SINGLE most important factor in determining wealth. In the past, geographic location determ...

I have no idea if I'm doing this correctly. Can someone please try to follow this reasoning and possibly correct it? Conditional Statements: 1. Unless the core generates enough heat for volcanic activity, surface will not be renewed. surface renewed --> core-heat-volcanic eruption 2. Any planetar...

Can we please go over this problem? Thanks.
