LG Game 1 Question 6 Explanation, by LSATHacks

To solve rule substitutions, you must consider all consequences of the setup diagram, including deductions and other rules. The right answer will tend to use some of those consequences to replicate the rule.

In the setup, we made the deduction that both G and H must have rural themes. This is because there are only two essays with urban themes. Since KF have different themes, they take one urban. And rule 5 says J takes the other.

That means everyone else has to be rural, so G and H must be.

So to replicate the full effects of the rule, we can do things in reverse. There are only three rurals. If G and H are rural, that leaves only two urbans and one rural. Add in J as urban (rule 5), and we’re left with one rural, and one urban theme for KF.

So, B is CORRECT.

A only gets us part of the way there. C, D and E add new restrictions that weren’t in the main game. The correct answer has to keep the constraints exactly the same, not change them.
