We can conclude from the first two paragraphs that whether a male practices monogamy of polygamy depends on ______.
A．the amount of nurturing the young
B．the sex of offspring
C．the attractiveness of his female partner
D．the time of conception
参考答案
正确答案：A
解析：推理判断题。从头两段中the business of feeding nestlings is so demanding和with little to contribute to the rearing process这两句话中，我们可知，选项A“养育后代的工作量”是对这两句的概括，故答案为A。B“后代的性别”、C“雌性伴侣的吸引力”和D“受精时间”都没有提到。
