Answer to Question 1

C

Answer to Question 2

In single-subject research, chance is ruled out by replicating the treatment effect. Although it is possible that chance or coincidence accounts for changes in behavior when the treatment is first introduced, it is very unlikely that chance will occur again a second, when the treatment is reintroduced.
