LG Game 4 Question 22 Explanation, by LSATHacks

To understand this explanation, you need to read the setup section. So do that if you haven’t yet. Here’s the setup diagram again:

LSAT Preptest 80, Game 4, Question 22, Diagram 9

In the setup, we saw that each group must have an ending value of six. Class 1 buildings are worth four, class 2 are worth two, and class 3 buildings are worth one.

This question says Trustcorp has no class 2. That means it must have a value of six, using only class 1 and class 3 buildings.

The only way to do that is to have one class 1, and two class 3’s, like Realprop has. Trustco could have either G or F, but they need to have both Y and Z.

E is CORRECT.
