In one experiment, rats were exposed to combinations of a tone and a shock. For one group of rats, shocks arrived 50% of the time without any warning; the tone therefore really provided no information. For another group of rats, shocks also arrived occasionally with no warning. But the likelihood of a shock was smaller (below 20%) when there was no tone than when there was a tone. What was the finding?
A) The second group of rats became fearful whenever a tone was sounded.
B) Both groups of rats feared the sound of the tone the same.
C) Both groups of rats came to fear any sound of any kind.
D) The first group of rats became fearful whenever a tone was sounded.
