Setup and Rule Diagram Explanation

This is a Pure Sequencing game.

Because Pure Sequencing is generally easy to handle for most test takers, this was an excellent way to begin the Logic Games section of the December 2013 LSAT.

The game scenario establishes that each of six films is scheduled to be released at a different time. Because there are no ties, this is a balanced game. The following linear scenario underpins the sequence:
Although Pure Sequencing games involve relationships that are relative and not precisely fixed, a linear diagram can help us represent inferences that could result from the application of the rules.

The first rule establishes the following sequence:
The second rule establishes the following sequence:
• K J H
The third rule establishes the following sequence:
• L G
When combined, the rules produce the following sequencing chain:
Since only K and F could be scheduled first, and only H and G can be scheduled sixth, we can represent these inferences on our Linear setup. Another interesting inference is that F must be either first or second. Thus, our final diagram looks like this:
In determining relationships between variables, do not let physical proximity on the diagram influence your evaluation. For instance, in the diagram K appears to be physically ahead of G, but in fact G could be scheduled ahead of K. The key in Pure Sequencing games is to avoid making unwarranted inferences such as this.

Sorry, just getting this straight:

So the final initial diagram tells us that spot 1 has to be K or F, but K could be in spots 1, 2, 3 or 4. Correct?

Hi med2law!

Correct! K and F are the only variables that could be in the 1st position. But K only has to have 2 variables after it so it could be 1, 2, 3, or 4.

Hope this helps!

Best,
Kelsey
