1. In an experiment, chimpanzees of a certain species gave researchers tokens from a bucket in exchange for grapes. For presentation of a grey token, the chimpanzee who presented it got one grape; while presentation of red token brought two grapes; one grape for that chimpanzee and another grape for an unfamiliar chimpanzee visible through a screen. The chimpanzees usually choose the red tokens. The researchers concluded that chimpanzees of that species are motivated by the desire to help other chimpanzees as well as themselves.
Performing one or more experiments to answer which of the following question would contribute most to evaluate the interpretation given to the experiment described above?
A Do chimpanzees of the same species as those in the experiment described above tend to prefer grapes over other fruits?
B If the chimpanzees were given more grapes for each color of token, than were given for those colors in the experiment described above, would the pattern of outcome be changed?
C Would using apes of a species different from the chimpanzees in the experiment described above give a different result?
D Which color preferences, if any, are found among chimpanzees of the same species as those in the experiment described above?
E Is the apparently altruistic behavior among chimpanzees in the experiment described above instinctive or learned?
