Explanation?

Hi, this is a game where the setup is almost the entire game. We have four spots in (ordered) and two which must be out _ _ _ _ (_ _) We also know that since both of our females are in, both our out group are males. We also know that since one lab is in and one is out, we have the breakdown of who is in and out. In: 2 f, 2 M, 1L, 3 G Out 2M 1 g/L 1 L Since we know that S is in, and S is a female lab, we know that U is out, and U is a male lab. So, we have a rough order to the six 1: P/R (greyhound, sex unknown) 2 P/r (G, sex unknown) 3: S (L, F) 4: Q/T (G, sex unknown) Outs: Q/T (?M), U(LM) If Q Is female, that means that Q is in and T is out. In this case, T could be either a G or L, making E correct.
