[2011Law]

Can anyone help me out with this one? The only answer I'm able to scratch out is D.

This is the set up I have for this one:

T W Y S V/X Z X/V

with 1, 5, 7 being new compositions and 6 obviously rock.

I think maybe I'm reading the prompt wrong, cause all I'm thinking is that there needs to be two songs that precede Y (and thus will also automatically precede V)

Well, you know that T,W,Y occupy the first three slots, which means that if there are two between V and Y that it has to go something like this: (this is because you know that Z cannot be last or 5th, meaning it must be 6th, as per the rock classic/new composition relation)

T Y W S V Z X

so A is out, B is out, C is out, you are left with D or E

T cannot be a rock classic as nothing can precede it, therefore the answer is E

To check: T=NC, Y=NC, W=RC, S=NC, V=NC, Z=RC, X=NC

IT WORKS!

Hope this helps
