Answer to Question 1

A

Answer to Question 2

The first design is a multiple-baseline across participants in which measures are taken at baseline and after the introduction of the independent variable at different times across multiple participants. The second design is a multiple-baseline across behaviors in which measures are taken at baseline and after the introduction of the independent variable at different times across multiple behaviors. Lastly, there is the multiple-baseline across situations in which measures are taken at baseline and after the introduction of the independent variable at different times across multiple situations.
