Rule #1: H __ __ + S or S __ __ + H Rule #2: PS or SP Rule #3: T = 1 or 7 Rule #4: not T1 (so T7) -> R1 not R1 -> T1 (so not T7) Rule #5: L - H
This gives us two basic framework options: (1) T __ __ __ __ __ __ 1 2 3 4 5 6 7 (2) R __ __ __ __ __ T 1 2 3 4 5 6 7
As for this specific question, we can go through rule by rule to eliminate answer choices. Remember that this question refers to spots 4-7.
(B) violates Rule #2 because P is not next to S. (D) violates Rule #3 because T is 6th. (E) violates Rule #4 because T is not first and neither is R. (A) violates Rule #5 because L cannot precede H. (C) is therefore correct.
Does that make sense? Hope it helps! Please let us know if you have any other questions!
