(E) is impossible because of the rule that O1 - R1.

That means that R's earliest audition is Thursday. This answer is saying R's second audition would be Thursday.

If R2 were on Thurs, R1 would be on Wed, and O1 would fall off a cliff.


We could otherwise resort to some plug and chug if none of the answers jumped out at us as a must be false.

(A)
G1, O1 | G2, R1 | R2 | O2

This scenario also proves that (C) can be true and that (D) can be true.

(B)
O1 | G1, R1 | G2 | O2, R2
