Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=6605)

The correct answer choice is (B)

The question stem establishes that Q and S both run in the meet, and from the first rule we can infer that T must also run in the meet, immediately after Q. Because the second rule limits S to running in just the first or third races, let’s examine what could occur in each scenario:

               If S runs in the first race, then R could run in the second race, and Q and T could run in the
               third and fourth races (S-R-Q-T). While this is just one solution with S running in the first
               race, it proves that S can run first.

               If S runs in the third race, then the QT block must run in the first two races. U then runs in
               the fourth race (Q-T-S-U). This proves that Q can run in the first race.

As we have explored all possibilities for who can be first based on the possible positions of S, we can determine that only Q and S can run first, and thus answer choice (B) is correct.
