Answer to Question 1

D
The ABA design does not include counterbalancing. When performance increases over all 3 conditions, it is impossible to conclude what caused the increase.

Answer to Question 2

A
The ABA design is a repeated measures design; hence there are no separate groups.. The alternate hypothesis states that there will be a difference among the groups, but does not say where or how many of the means will differ.
