LSAT PrepTest 21, Section I, Logic Games, Question 3 Explanation

LG Game 1 Question 3 Explanation, by LSATHacks

A is wrong; we know from the last question that Lee could share a single but doesn’t have to. The second scenario above proves that wrong.

B is CORRECT. Pat is always with K. K can’t be in a triple so they must be in a double.

C, D, and E are all proved wrong by the previous question.

In question 2, we’re told that Robin could be alone in a single so C isn’t right.

D could be true but we also have the scenario from question 2 where S, T and V are in a triple and L is in a single.

E is wrong because R (a third year student) is assigned to a single in Question 2.
