LSAT 65, Logic Game 4, Question 20, LSATHacks

There are two possibilities, if S is third. Either S is in the 3rd slot:

Or S is in the 4th slot, but is the third program, because GG comes earlier. GG would have to go first:

Let’s try to complete the first diagram. 

We know R has to go before S. And in this diagram, GG has to go at 3 o’clock, because it’s the only open spot left that is on the hour:

T and W are left. There aren’t two open spaces to place WT, so T must go somewhere before W instead (rule 4):

R goes first and T goes second because T must go on the half hour.

Let’s try to fill out the second diagram, where GG goes first and S goes in the fourth slot. 

We know R goes before S:

Only T and W are left. T has to go on the half hour, so we get this order:

In both diagrams, W is fourth. E is CORRECT.

The other answers don’t have to be true. At least one diagram shows that each of the other answers could be false.
