We're asked to distribute the names of plays among 5 people, JKLMO. Each of them reviews "one or more" plays. (Under each person there is at least one slot.)
The first clue tells us K and L review fewer than M. Since everyone already has one, M has to review at least two. (At least two slots under M.)
The next clue says neither L nor M review anything J reviews. There are only three plays, and J is reviewing at least one of them, which by this clue M cannot also review, so M is stuck reviewing (only) the other two. (Make some mark to show that M has no more slots).
Now stop and make some connections. First, if K and L have fewer slots than M, and M has exactly two, K and L must have exactly one. Also, if there are three plays, and M reviews two of them, and J can't review anything M reviews, the third must be the only one for J. (Mark that K, L, and J have no more slots.)
K and O both review T (update diagram--notice how K gets to review T and only T).
Exactly two students review the exactly the same plays. Make a note and don't forget it.
So now we should have a fairly tight diagram. J, K, and L each have exactly one slot. K's slot is filled with T. M has exactly two slots. O has at least one slot filled with T, but may end up with one of two more.
Who could review only sunset?
Well, we know M reviews two, so cross all the answers with M out. That kills E. We know that K and O review T, so cross all the K's and O's out. That kills B and D. Our remaining answer choices say either L or L & J. We had a rule that said L and J can't review the same plays. That kills C and we're left with A.
What must be true?
A. No, J only reviews 1. Cross off.
B. M reviews 2, J reviews 1. Done.
If exactly 3 review U, what could be true?
K is already spoken for, leaving JLMO. To pick 3 of those four, J has to be the odd man out. So we know L, M, and O review U, and J doesn't. Kill A, B, & C. L reviews only one, which we said has to be U. Kill D. E is all that's left.
Who could all review T?
Our diagram should remind us that K and O have to review T. We also know that between J and M, all the plays are reviewed, so one or the other must also review T. Which answer has both K and O AND has one of J or M? Answer D.
If J doesn't review T, what must be true?
Again, we know that between J and M, all the plays must be reviewed, so the first thing that should pop in our heads is that when J doesn't review T, M does. Answer D.
