If we pair a tone with a shock,a rat can learn that the tone predicts the shock.If we then pair a tone and light with a shock,we find that the rat gives a:
A)CR only to the tone.
B)CR only to the light.
C)UR only to the tone.
D)CR only to the tone and light together.

The rat only learned to associate the tone with the shock, so it will only give a conditioned response (CR) to the tone. It has not learned to associate the light with the shock, so it will not give a CR to the light. Similarly, since the shock naturally elicits an unconditioned response (UR), the rat will show this response to the tone even in the absence of the shock, but not to the light. Finally, since the tone and light were presented together with the shock, the rat may show a CR to both stimuli when presented together, but this is not the best answer since the question specifically asks about the rat's response to the tone and light presented separately.
