This is an explanation of the third logic game from Section III of LSAT preptest 67, the October 2012 LSAT.
A toy retailer is opening a small satellite store. There will be three aisles (1, 2, 3) and six sections: Fantasy, Hobbies, Music, Puzzles, Reading, and Science (F, H, M, P, R, S). Each aisle will have at least one section.
This is a grouping game with sequencing elements. I found it easiest to represent vertically. You can draw it horizontally if you prefer. These things are just a matter of taste.
The first rule:
The second and third rules:
The fourth rule:
Just memorize the fourth rule
The fourth rule is harder to draw. H can be before S OR in the same group as S. That’s why you can’t just attach this to the diagram I drew with F, S, M, P.
Since it’s a hard rule to draw, I prefer to just memorize it. I try to keep space in my head for at least one rule to memorize. It makes things go much smoother.
Try it, it’s easier than you think to memorize rules. Just take 20-30 second pre-game to load them into your head and repeat them mentally.
There are no deductions to make in this game (apart from combining rules 2 and 3). Instead, you’ll have to know the rules well and apply them quickly.
If you can’t memorize the rules, then at least make a list like I’ve drawn in the main diagram section, and refer to it for each question.
Rules 2 and 3 present the main limit in this game. There are only three groups, and many questions artificially block off one group. That means that F-M&P or S-P will be split between the remaining groups.
