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.

Summarize Argument: Phenomenon-Hypothesis
The zookeeper hypothesizes that Jocko’s silence was meant to keep the other chimpanzees from taking his food. She supports this by showing that Jocko only remained silent after an earlier incident, where his bunch of bananas were taken away by other chimpanzees after he barked excitedly.

Notable Assumptions
The zookeeper assumes that the difference between Jocko’s reactions weren’t a result of getting a different quantity of food: the first day he gets a bunch of bananas, whereas the second he gets only one. This means the zookeeper doesn’t believe that Jocko was actively trying to share his food the first time, or that the quantity of food itself didn’t cause him to bark out of excitement.

A
Chimpanzees utter food barks only when their favorite foods are available.
Jocko received bananas both times. He didn’t bark the second time.
B
Chimpanzees utter food barks only when they encounter a sizable quantity of food.
Jocko wasn’t trying to keep the others from taking his food the second time. He simply hadn’t received a sufficient quantity of food to utter a food bark.
C
Chimpanzees frequently take food from other chimpanzees merely to assert dominance.
Perhaps that’s what happened the first time, but we don’t care. We’re looking for something to weaken the claim that Jocko didn’t bark the second time to keep other chimpanzees from taking his food.
D
Even when they are alone, chimpanzees often make noises that appear to be signals to other chimpanzees.
Jocko didn’t make any noise the second time. We need to know why.
E
Bananas are a food for which all of the chimpanzees at the zoo show a decided preference.
We need to weaken the zookeeper’s claim that Jocko kept quiet to protect his food. This just tells us all chimps like bananas.
