A serious problem of interpretation can arise in the ABAB design when
A)performance in the initial baseline period is too high or too low.
B)performance in the second baseline period does not reverse,that is,return to the level in the initial baseline period.
C)performance in the second baseline period is worse than it was in the initial baseline period.
D)performance improves to the same degree in both intervention periods.

The ABAB design relies on the reversal of behavior in the second baseline period to demonstrate the effectiveness of the intervention. If behavior does not reverse, it becomes unclear whether the intervention actually caused the change in behavior or if it was due to some other factor. Therefore, a failure to demonstrate a reversal of behavior in the second baseline period can undermine the validity of the ABAB design.
