Complete Question Explanation
(The complete setup for this game can be found here: lsat/viewtopic.php?t=1753)

The correct answer choice is (A)

If L is within exactly three areas, L cannot be in area S (if L were in S, then it could only be in S and T) and therefore L must be in areas R, U, and T:

Since L and M cannot be in the same detection areas, M cannot be in areas R, U, and T, and therefore answer choices (D) and (E) are incorrect. Since M must be in at least one detection area, it follows that M must be in area S. According to the Not Laws in our initial setup, K can never be in area S, and therefore answer choice (C) is incorrect. In answer choice (B), it is impossible for J to be in three areas since any plane in area S cannot be in area R and U (and plane J is in area S from the second rule). Thus, J can only be in at most two areas. Since answer choice (B) is incorrect, answer choice (A) is proven correct by process of elimination.
