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， bread 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， tamatins 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？
书上给的答案是E 将小猴子笼养不会影响他们的交配行为，可是前面题目中不是已经给出On the basis of the fact that breeding occurred了吗？那这个怎么还能成为假设呢？我怎么觉得好像A比价靠谱啊，但是也不是说完全明白，求高人讲解啊，多谢。
IMHO, GWD's assumption questions have flaws. "Questionable assumption"? We are not dealing with weakning and strengthening type of questions here.
If you put a man and woman in a small room without other people, let them sleep and live together, of course they will breed frequently and grow quickly. Since when babies will hamper the parent to have the act which is vital to reproductions. Look at the Mexicans!
