#10 - Local, Must Be True

[Dave Killoran]

Complete Question Explanation

The correct answer choice is (E).

The condition in the question stem can only occur under Template #2. In that template M’s stall and G’s stall are always in the same row (the first row), and thus answer choice (E) is correct.

This question stem can only lead to one template:

(F, G) - M
K - J - H

But there seem to be two answers that must be true?
C. G is assigned to a lower-numbered stall than M.
(Yes, it must be true. Whether G is in 1 and F is in 2, or F is in 1 and G is in 2, G will always be lower than M, which is 3.)
E. M's stall is in the same row as G's stall.
(Again, this must be true, whether G is in 1 or 2.)

The right answer, apparently, is E. Why is C not right? Have I overlooked a possibility somewhere?

Hi Lily,

The diagram I got here with the addition of this new rule is:
__ - M/ - /M (with F and G filling the empty spots)
K - J - H

That leaves the only correct answer as E.

If you can walk us through how you got to the template you used for this question, we can try to help explain a bit more!

your M/ made me realize my error. I had placed M in the 3rd slot only, but it could have been in 2 or 3.

I just overlooked a template when I drew my diagram. Oops.

Thank you for your response!
