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 (D)

The conditions in the question stem produce the following initial diagram:

From the second and third rules, the fifth bead cannot be R or O:

At this point, the inference stream appears to stop. So, where should you look to help solve the problem? The key here (as in #16) is to apply the space-eating first rule. If the fifth and sixth beads are P and Y, then the seventh bead will be R. From the third rule the eighth bead cannot be O, which will ultimately cause a violation of the fourth rule because there will be no room for O among the first eight beads. Hence, P and Y cannot be fifth and sixth, and answer choice (D) is correct.
