I was wondering if anybody had an explanation/thought process for question 2. Having difficulties. Any help is much appreciated.
Thanks!

Re: Question 2
Happy to help.
The information contained in the question stem plays nicely into the constraints.
For this question X immediately precedes Q, and not forgetting the 1st and 2nd constraints, we get a chunk that looks like
RXQ -- W
If you set up frames with either Q or else T in the fourth position you would have
_ _ _ Q _ _ _
_ _ _ T _ _ _
1 2 3 4 5 6 7
For the top row, R and X must come 2nd and 3rd. And since the RXQ chunk precedes W, we can say in the bottom row that RXQ will go 1st, 2nd, and 3rd respectively. There's just no room to put RXQ and then W behind T.
_ R X Q _ _ _
R X Q T _ _ _
1 2 3 4 5 6 7
The rest of the bottom row falls into place by following the rest of the constraints.
_ R X Q _ _ _
R X Q T P W S
1 2 3 4 5 6 7
Using these frames we can eliminate answer choices (B), (C), (D), and (E).
Does that help?
