I had the same problem. I just finished going through the core curriculum on NA questions again. I feel like the key is to use the must be true method to narrow down your options and then use the negation test to confirm your answer. Once you've got the hang of it just do the NA problem sets in the CC until you have it down reasonably. If you find that NA questions are a time-sink, flag it and come back to it later. If that time is better spend getting other questions, move on.

This is one of those things where practice and slowly being able to visualize the board while reading the stimulus will come into play. It took me running through various logic games over 100 times (some games i did 4-5 times each) before I started to get to that point.

Don't worry, trust the process. Practice, practice, practice. It'll come.

Picked D because I thought of "is best qualified" as a universal statement (absolute statement) vs the relative comparison between the different candidates.

Most unique therefore best qualified. Using a relative comparison to make an absolute statement? No?

There is a gap in reasoning between the premise and conclusion:

(P) such enthusiasm may also indicate that the candidate is less concerned with work than play.

(C) Therefore the managers shouldn't inquire about hobbies.

4 answers will expose this gap, i.e. will provide reasons why the manager should inquire (benefits)

1 answer will not expose this gap.

B is the correct answer.

I was wondering the same thing. I thought maybe its best to drill 5 passages at a time so that we get used to the longer duration and a regular 4 passage feels easier? Not sure tho. RC is also my weakest, and I'm just trying to solidify the habit of low resolution summaries before my feb test date which is coming up.

Let me know what works for you.
