LG Game 3 Setup, by LSATHacks

Game Setup

This is a grouping game. The rules are straightforward, with one twist. There are six spots, but seven researchers. They go on two teams.

The researchers are split into anthropologists and linguists. Each team has at least one anthropologist and one linguist. There are only three anthropologists: F, J and M. At most two of them can go on a team.

It’s important to remember that each team must have one of F, J or M. Here is a good way to draw this setup:

If you are ever unsure of how to draw a setup, you can look at the first question of the game. In this case, they set it up the same way.

The first three rules tell us who can’t go together. F and S are apart. R and N are apart and M is not with R or S.

You could draw these right in the diagram….if you knew that everybody was in. (The pairs would be split between groups). But we can’t, because not everyone goes in.

You can make additional deductions by rearranging things to show who R can’t go with and who S can’t go with.

If you have R then you don’t have M and N. If you have S then you don’t have M and F. M and F are two out of three anthropologists. So if you have S you must have the other anthropologist, J.

The last rule tells us what happens when J is in 1.  R is in 2. M and N don’t go with R, so they aren’t in 2.  Both J and M aren’t in 2, so we need to put the other anthropologist there: F.

One other thing you should do before moving on is to write down all your variables. Identify the random, which is O. O can go with anyone.
