LSAT 70, Logic Game 1, Question 3

This question tests your ability to apply the ordering rules. Let’s look at them again:

The question places V third:

We know that Y has to go in slots 1-2. Who else can go there?

Not U. They must go 4-6.

Not Z. They must go after V

Not X. They must go after Z.

So only W can also go in slots 1-2. We get this diagram:

The commas indicate that variables are interchangeable, while the line between Z – X indicates that there’s an ordering rule for them to obey.

You might have seen Powerscore draw Y and W like this: Y/W   W/Y

That works too. However, that method doesn’t work well for slots 4-6, which is why I prefer my more flexible method. You get a very clear view of where every variable can go.

B is CORRECT. W has to be 1st or 2nd, so they are always before Z in this scenario.

A, C and E are wrong because U could be before Z – X, in between them, or after them.

D is wrong because Y and W are interchangeable in this scenario.
