We can infer that the chance for female marmoset and tamarin monkeys to have twin births depends on ______.
A．the number of male they have access to
B．the workload they have in bringing up the young
C．the time when they come into estrus

参考答案
正确答案：B
解析：推理判断题。根据文中第五段可以判断出选项B“她们在养育后代中的工作量”是与文章中第五段所作的论述完全符合的。A“她们所能接触到的雄性数量”与文章的论述在逻辑上不符：C“她们进入发情期的时间”和D“雄性动物的体型大小”在第五段中根本没有提到。
