The condition we get is M = 3, so we draw a number line and plop him in.

__ __ M __ __ __ T

If we look at our rules for anything about M or spot 3, we see that we need 2 M's and have to accommodate a G in between them.

Could the M in spot 3 be either the first M or the second M, or could it only be one?
(that's one idea for framing possible scenarios)

M G M __ __ __ T
or
................(G - M)
__ __ M __ __ __ T

Who's left?

Our big priority in ANY game is a chunk, if the game has a chunk. This game involves a GJ chunk, so we should think about where that could be.

................(GJ, ?)
M G M __ __ __ T
or
...........(G - M)
G J M __ __ __ T

Maybe that's enough work to judge the answers.

We know that spot 4 can't be J (ever) and can't be M (because spot 3 is M), so spot 4 has to be G or T.

That eliminates (B) and (C).

Let's test the remaining ones with our frames.
(A) is GT possible in either frame?
Looks like it's fine in the 2nd one: G J M G T M T

(D) Is TJ possible in either?
No, because we have (GJ, ?) or (G - M, ?) as our two options for spots 4/5/6.

TJ can't fit in either of those.

(E) Neither can TM.

CORRECT ANSWER IS (A).
