Answer to Question 1

C

Answer to Question 2

Baseline phase is typically the first stage when the target behavior is exposed to the status quo; in other words, no experimental intervention is in place although existing procedures may be in place; this phase establishes present levels of performance on the dependent variable
Intervention phase typically follows the baseline phase and is when an intervention is introduced and manipulated by the researcher to encourage change in the dependent variable
Follow-up phase typically follows the intervention phase and is used to determine if changes in the dependent variable (target behavior are maintained over time; in many instances, the intervention is no longer in effect during a follow-up phase but it could still also be in effect
