@Kath,Generally if a question presents a hypothetical, it means that this hypothetical could be true - otherwise, one of the answer choices would have to say "no valid answer" -and I am not aware of any LSAT game that had this scenario.

The question asks us which of the following must be true if S is first. The rules tell us that S must perform earlier than T, and H must perform later than both T &S - in this scenario H cannot perform earlier than both of them since S is #1, H must perform earlier than R, resulting in the following order:

S > T > H > R

G is the only one remaining and the rules tell us that if G performs earlier than T, then R & S must perform earlier than T but that's impossible based on the inferences above T > H > R, thus we can conclude that G must perform later than T but we cannot determine its exact position in relation to H &R, so our order could be any of the following if S is first:

STGHR

STHGR

STHRG

We can see that four of the answer choices could be true - G could be #3 and #4, H could be #3, and R could be #5, but T must always be #2 in all of three possible scenarios, thus we can conclude that (E) must be true.

Let me know if this makes sense and if you have any further questions.
