June 2007 LSAT, Logic Game 4, Question 18

LG Game 4 Question 18 Explanation

For acceptable order questions, go through the rules and use them to eliminate answers one by one.

Note that I use the rules themselves. I don’t use my diagrams for these questions. Reading the rules again for this question will help you memorize them, and it’s also more efficient.

Rule 1 eliminates A. W needs N, in center 3.

Rule 2 eliminates C. All the materials in center 2 need to also be in center 1.

Rule 3 eliminates D and E. In D, you can’t have glass and plastic together. In E, you can’t have plastic in more than one center.

B is CORRECT. It violates no rules.
