LG Game 1 Question 3 Explanation, by LSATHacks

On this question, you can use past scenarios to eliminate answers. Also, note that Shahpari has no rules, so it’s easy to move them around.

The first three answers all place S in the morning. If you look at the correct answer to the first question (A), you’ll see that S is in the morning, between R and Z. That makes it very unlikely that any of the “S in the morning” answers are correct. When I was doing this, I skipped immediately to D and E.

But let’s conclusively disprove the first three answers. The only rule for R and Z is that R goes before Z, and Z goes in the morning. So we can rearrange the answer to the first question to place S first, second or third: before, in the middle of, or after R – Z.

This shows that S can go anytime in the morning, and disproves A, B and C.

Next, look at this diagram from question 2:

This proves that S can go at 3 p.m., which eliminates E. So D is CORRECT, by process of elimination.

As a review exercise, it’s helpful to figure out why S can’t go at 2 p.m. Let’s try it and see:

As soon as I drew the diagram above, I saw why D couldn’t be true. Since R–Z are in the morning, there’s only one space for WY. And since T also has to go in the afternoon, there’s only one afternoon space. WY need two spaces, so there’s nowhere to put them.
