Answer to Question 1
Answer: A
Answer to Question 2
Answer: The supplemental motor area (SMA) and the premotor area lie just anterior to the primary motor cortex. These two regions exert influence on the primary motor cortex to modulate its control of motor function. In general, the SMA plays a role in planning of behavioral sequences, such as pressing a series of buttons. Inactivation of the SMA did not alter reaching, but did disrupt the ability to make a series of already learned responses. In contrast, the premotor cortex is important for using arbitrary stimuli to guide motor reactions.
