I was able to narrow it down to (D) and (E), but couldn't both (D) and (E) be true. I made 4 frames for this game and using the 3 three last frames:
S S O _ _
P S S _ _
P O/P S S O/P
P O/P O S S
I got rid of choices A, B, and C because P has to go on Monday. However, couldn't P be on Tuesday (as shown in frames 3 and 4) and couldn't O be on Wednesday (as shown in frame 4)?
If someone could point out what I'm missing here, that would be great! Thanks!
