None of the black men won the right to vote until after the civil war.

Answer:
The correct answer is C. Neutral stimulus: knock on the door; CS: knock on the door; UCS: cocaine.
Explanation:

- The cocaine is an unconditioned stimulus since at first it only generates Alexis's shakiness and heart pound.
- Once the <em>neutral stimulus </em><em>mixes </em><em>with the unconditioned stimulus,</em> the neutral stimulus (knocking on the door) becomes a conditioned stimulus since it will make Alexis nervous as she is expecting the dealer.
