LSAT PrepTest 31, Section I, Logic Game 3 Setup

LG Game 3 Setup, by LSATHacks

This is an explanation of the third logic game from Section I of LSAT preptest 31, the June 2000 LSAT.

A company’s three divisions – Operations, Productions, Sales (O, P, S) – will be toured five times during a single week. One tour will be conducted each day, from Monday through Friday (M, T, W, Th, F). You must use the rules to determine the schedule of the tours.

Game Setup

This is a linear game, and it’s a little more complicated than it looks. Though there are only five tours, there are not many rules to tell us how often each division is toured.

The first rule says each division has to be included. That’s important to remember.

You can put the second and third rules directly on the diagram:

The fourth rule is important. The two S’s are beside each other. You can draw it like this:

There are only the two S’s. We can combine this with the first rule, and realize the other variables must either be:

Two O’s and one P
Two P’s and one O

This rule about S also greatly restricts which division can be toured on Monday and Wednesday.

Many questions tell you when S is toured. If S isn’t toured on Wednesday, then O must be toured on Wednesday (because P can’t B).

And if you know S isn’t toured on Monday, then P has to be toured on Monday (because O can’t be). This is extremely important, as it answers questions 16, 17 and 18.

The final rule doesn’t connect with anything else. If just tells us what happens if O is inspected on Thursday.
