Answer to Question 1

B

Answer to Question 2

Both are subject effects that threaten internal validity. The Hawthorne effect refers to the tendency for subjects in the experimental group to change their behavior because of the attention gained from participating in an experiment. The John Henry effect refers to the tendency of control group subjects who know they are in an experiment to exert extra effort and perform above their typical average.
