Answer to Question 1

D
Variables in which knowing what the manipulation is doesn't reveal the hypothesis of the experimenter work best with repeated measures designs.

Answer to Question 2

C
Between subjects factorial designs present each participant with only one condition, thereby making it impossible for them to compare treatments, and making it unlikely that demand characteristics will be present systematically in the study.
