Q22

[CesarF24]

Anyone know how the answer is determined for Q22?

[Misti Duvall]

This is a tricky question! Here's how I did it:

If M is on Thursday, so is L, and either M is only on Thursday (and is therefore the sole non-repeater) or it repeats on one other day. So I started by framing.

If M is only on Thursday, it's got to be:

T: M L P
F: N Q P
S: N Q L

Since this is a must be true question, we can use the first frame to eliminate anything that we made untrue. So we can eliminate (A) and (B).

If M repeats, it has to be Thurs and Sat (cause if it's Thurs and Fri, two Qs get jammed into Sat), so the next frame is:

T: M L __
F: N __ __
S: M L __

P and Q are left, and one of P, Q, or N has to be the non-repeater.

Looking at the remaining answers, we can eliminate (C) because N could also be on Thurs or Sat (or not repeat). We can eliminate (D) because P could be Thurs, Fri, or both.

Which leaves (E). If Q is not on Friday, we couldn't fill it up, cause only N and P would be left for the remaining two spots and N can't repeat in the same group. So Q must be on Friday.
