Eactly eight artists - O, S, P, R, T, V, W and Y - enter an art competition. The competition judges rank the artists from 1-8. There are no ties and the rankings conform to the following:

Either P or W is ranked fourth

R is ranked either first or eighth

Y receives a ranking that is numbered two lower than that of O

T is not ranked fifth

A

Setting up frames not worth it - is an 8-slot setup meaning there will be many possibilities. While slot 4 is fixed there are two possibilities P or W which will double the number of possibilities. While R is limited, there are two possibilities for R. The chunk Y_O can be placed in a number of positions: 1_3, 3_5, 5_7 and 6_8
