Jocko, a chimpanzee, was once given a large bunch of bananas by a zookeeper after the more dominant members of the chimpanzee’s troop had wandered off. In his excitement, Jocko uttered some loud “food barks.” The other chimpanzees returned and took the bananas away. The next day, Jocko was again found alone and was given a single banana. This time, however, he kept silent. The zookeeper concluded that Jocko’s silence was a stratagem to keep the other chimpanzees from his food.

Which one of the following, if true, most seriously calls into question the zookeeper’s conclusion?

(A) Chimpanzees utter food barks only when their favorite foods are available.
(B) Chimpanzees utter food barks only when they encounter a sizable quantity of food.
(C) Chimpanzees frequently take food from other chimpanzees merely to assert dominance.
(D) Even when they are alone, chimpanzees often make noises that appear to be signals to other chimpanzees.
(E) Bananas are a food for which all of the chimpanzees at the zoo show a decided preference.

Conclusion: Jocko’s silence was a stratagem to keep the other chimpanzees from his food.
Assumption: The zookeeper makes a ludicrous assumption that the reaction of Jocko to a large bunch of banana is the same compared to that to a single banana. He ignores the fact that Jocko's silence could be because of difference in the quality of banana.

A. Out of context. It is no relevant to know whether Chimpanzees utter food barks only when their favorite foods are available.
B. Correct Answer. Brings into the context that the zookeeper totally ignored that Jocko's silence could be because of difference in the quality of banana
C. Out of context. Why Chimpanzees frequently take food is not important.
D. Out of context
E. Out of context
