问题 In the 1960’s, long-term studies of primate behavior often used as subjects tamarins, small monkeys that were thought ideal because they require only small cages, breed frequently, and grow quickly. Field studies were not used because they were costly and difficult. Tamarins were kept caged in male-female pairs, because otherwise, serious fights erupted between unrelated females. On the basis of the fact that breeding occurred, tamarins were viewed as monogamous. The view taken by the researchers concerning the monogamy of tamarins depended on a questionable assumption. Which of the following could have served as that assumption?
选项 A、The suppression of fighting between related females serves to protect their common genetic inheritance.
B、Adult male tamarins contribute to the care of tamarin infants.
C、The social system of tamarins requires monogamous pairing.
D、Male taniann monkeys do not display aggressive behavior in the wild.
E、The way the tamarins were kept in cages did not affect their mating behavior.
答案E
