@Jaimee-Salgado if R is the second slot, it would be at either 1:30 or 2, depending on whether G is first.But can R actually appear at 1:30? Only if S T or W appeared at 1.

We know that T can't be at 1pm because of rule 2.

We know that S can't be at 1pm because R is shown before S according to rule 3.

We also know that if W is shown before T, which would be the case if W was at 1pm, T must be immediately after W, which would mean T would be at 1:30pm which can't be true.

This means that R can't appear at 1:30pm, which means the following scenario must result:

1 G G

2 R

Now let's take a look at (D), which would put W at 2:30pm as follows:

1 G G

2 R W

3 T S

Notice that W at 2:30pm would invoke rule 4, which means T must be shown immediately after W. That would place T in 3pm, which VIOLATES rule 2 that requires T to start on the half hour rather than the hour.

So (D) cannot be true so (D) would be the correct answer.

Hope that helps! Please let us know if you have any other questions.
