LSAT 28, Logic Game 2, Question 12, LSATHacks

If the historian just learns two languages then we are in this scenario:

The geologist learns one language, T or S. The historian learns that same language plus Y.

The linguist and paleontologist learn the remaining language out of T or S. One of them learns R.

A could be false. R could be learned by either the linguist or the paleontologist.

B doesn’t have to be true. The geologist could learn S if the linguist and paleontologist both learn T.

C doesn’t have to be true. Either the linguist or the paleontologist could learn R.

D is CORRECT. If the historian just learns two then he always learns Y and one of T and S. That leaves no space for R.

E could be true but doesn’t have to be. The paleontologist could learn S if the geologist and historian learned T.
