If (E) had been flipped around a bit to say, "The argument concludes a lack of evidence on the basis of a lack of a known causal connection ," would it have been right? It seems that (E) is very close but just turned around a bit. Also, doesn't (D) actually happen even though it is NOT th...

First, let's think about what the paradox is. The paradox is that now insurance companies don't have to pay for as many things as before, so they should in theory make their rates cheaper. But the opposite happens - even though they now pay for less, their rates have gone up! Let's take a look at (...

Good discussion guys. The point here is that the people who started business had already lost their jobs; that was already reported to the gov't, and THAT is what was underestimated. It doesn't matter if they started business later--the question isn't about later. It's about why the numbers reporte...

What does answer choice mean? I realize this might be to late to answer this question, but someone else might find this helpful. So what does the A/C say: " It mistakes something that is necessary for its conclusion to follow for something that ensures that the conclusion follows." First ...

The reason why (B) does not undermine the argument is that people can continue to buy cigarettes but they can decrease the frequency of it: Instead of buying 4 packs of cigarettes a week I'll buy 2 packs, but I will continue to buy cigarettes. Continuing to buy does not necessarily mean not decreasi...

I think you are both missing that they also used "some" in the answer choice. So even if some also might mean all, then in answer choice it might also mean all!

E is incorrect because there was no such presumption. People who were surveyed do not need to base their responses on a random sampling of movies. It is the people who must have been randomly selected which of course was not carried out and hence D is correct.

Pat says: some good actions have ~(favorable consequences ), actions considered bad --> ~(favorable consequences) and concludes: some actions that are considered bad are actually good. How did she get to her conclusion? This way: there are actions that have no favorable consequence(It is a necess...

But Gregory is not saying that the committee will eliminate irresponsible analysts from courtrooms. He is saying that the committee will deter them from making exaggerated claims. So even if they are the only people who would testify, (D) does not weaken Gregory's argument.
