Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=12911)

The correct answer choice is (C)

This Global, Must Be True question directly tests the main inference in this game, which results from the contrapositive of the second rule: if P were not used, then O could not be used, which leaves only four thread colors available for the three rugs. However, since exactly five colors must be used, we need to ensure that P is always used in one of the rugs. This prephrase is key to quickly identifying the correct answer choice (C).

Answer choice (A): This answer choice is incorrect, because F could be used in a multicolored rug without violating any of the rules.

Answer choice (B): This answer choice is incorrect, because T could be used in a multicolored rug without violating any of the rules, as shown in the 2-2-1 distribution.

Answer choice (C): This is the correct answer choice.

Answer choice (D): This answer choice is incorrect, because T need not be used in any of the rugs as long as we adhere to the 3-1-1 distribution:
