I did not understand how to do the formal logic diagram on this. I had it down to A or D, but ended up picking the wrong answer (D) because it mirrored the original more in wording (both use "but since").

Can anyone explain how A is similar to the original stimulus?

Could someone explain why B is incorrect?

thanks!

Concerning Q19, at the first time I read it, I was confused about "Krall" because there is no explanation about Krall.
As I understood, about the part "Arvue should not hire Krall" in the application, is it right that the reason the answer E does not comment about Krall is that the principle does not mention "should not hire"?

And I have trouble with Q20. Why is it the answer is A?
I think the ...

I totally don't get why the answer to question 5 is E (S was begun in 603).

Since "L was begun a year later than G" therefore GL is a block, and the question asks what must be true if L was begun in 602 - so how is G was begun in 601 NOT the correct answer???

Could someone please post an explanation about this one too? I find it hard to distinguish between comparing Mars and Earth when they have differenet gravity... and then comparing their crust when they have simliar gravity... thanks.

This one caught me off guard as unusually difficult for being so early in the section because of the attractiveness of both the right answer (A) and the wrong answer (E). It seems that "vividly remembering the pain caused them in the past by their bad habits" would be an equally good alternative to allowing them to successfully change a bad habit. I ended up choosing A simply because it seemed to "flow" better with ...

Okay...I remember not liking any of these answers, really. And while E makes sense I guess, I have no idea how we're supposed to figure out that E is the flaw. I mean, we don't know WHY the airport is being built; structurally, the argument commits a negation but there wasn't anything like that in the answer choices. Is it because what development companies DO is 'develop' economies? I wasn't sure about that when I ...

Can you please explain why D is a better answer choice than A? I was very torn and answered this incorrectly. Thanks.

Under untimed condition (about 1.75 mins/question on average), my accuracy rate is higher (-3 ~ -5 for 25 questions in 45 mins). However, when I tried to complete more questions under timed condition (35mins), I had more questions incorrectly answered and those questions are not especially difficult. Even worse, some are quite easy ones which I can correctly answer under untimed condition. My accuracy rate is negatively correlated to the completion rate. So, how to ...

Hey guys, I really don't get why the answer is D and not E. Thanks!
