#13 - Global, Could Be True, List

Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?f=357&t=12842)

The correct answer choice is (C)

In applying the traditional List question approach, remember to apply the rules in the easiest-to-apply and most efficient manner. Thus, in this game, do not start with the last rule—it’s too time consuming. Use the middle two rules first, then the first rule, and then the last rule.

Answer choice (A) is incorrect because it violates the third rule.

Answer choice (B) is incorrect because it violates the second rule.

Answer choice (C) is the correct answer.

Answer choice (D) is incorrect because it violates the third rule and the first rule.

Answer choice (E) is incorrect because it violates the fourth rule (there is no O bead).

Hi,

I eliminated choice (C) because of the third rule, the yellow-purple sequence did not have red beads on either side. Could you please elaborate?

rule: R P/Y Y/P R

You may have misunderstood that rule, Mmjd12. It doesn't require that reds be both before and after that Purple/Yellow pair. That wording of the language is conditional: ANY bead that immediately follows and ANY bead that immediately precedes must be Red. Read those "any" statements as if they say "if." In other words, IF there is a bead right before the pair, it must be Red, and IF there is a bead right after that pair, it must be Red. Starting or finishing with a Purple/Yellow pair is okay, as long as any bead that is right before it or right after it is Red.

So, you can start a string with Purple-Yellow-Red, or you could end with Red-Purple-Yellow, and in both of those sequences the Purple and Yellow beads could switch places with each other.
