Answer to Question 1

B

Answer to Question 2

An ABAB design is better than an ABA design for two reasons. First, it allows us to further assess the effectiveness of the independent variable by introducing it a second time. Second, it leaves the participant with the treatment, rather than leaving them with the baseline (no treatment) condition. Thus, it is more ethical than the ABA design.
