Games Page 118 and "Must be true" questions

First, a question about the set-up for a game like the one on page 118. This appeared to be a standard binary grouping game, with the additional factor of the selected items being ordered. I didn't have any trouble with the game, but I just wanted to confirm that my set-up was ideal, and whether or not these type of "binary with ordering element" games appear often. I basically just drew a standard ordering template with 1-5, and then an additional "OUT" column with two spaces in the template. 

My second question is about "what must be true if" type questions. If I have previous work containing the condition that comes after the "if" part of that statement, any answer choices that DO NOT occur in my example can be eliminated correct? And any answers that DO occur can be considered possible, but not necessarily correct?
