LSAT Question Analysis #5

It’s an ugly, rainy, windy day in Washington and all of my lessons are canceled. I’m going to dig into 10 New Actual, Official LSAT PrepTests and do a logic game to pass the time. Let’s try PrepTest 57, Section 1, Questions 1-5 (10 New LSAT, page 188).

This looks like a relatively straightforward ordering game. The items are G, H, J, K, L, and M. I’ll shorthand the rules as follows:

(1) HG
(2) K-G
(3) M-L
(4) JM or MJ

The repetitions of G between rules 1 and 2 and M between rules 3 and 4 are surely not accidental.

LSAT Question Analysis #2

Building off the formal logic posts of the last two weeks, today we’re going to discuss the LSAT logic game found at PrepTest 58, Section 3, Questions 7-12 (10 New LSAT, page 241).

This is a fairly simple In-and-Out game (also known as a Selection game). Such games often involve heavy doses of arrow diagramming, and this one is no exception. Take a quick read of the setup and then let’s turn our attention to the rules.

The rules of this game can be diagrammed in straightforward fashion as follows:

1. R→M
2. M→T
3. !S→V
4. !R→L
5. T→(!F and !V)

Let’s turn to the questions now.
