问题 Human males living with their moms may not expect to have much luck hooking up this Valentine’s Day.(1)_____ among the northern Muriqui monkeys, males that spend the most time around their mothers seem to get a(n)(2)_____ boost when mating time rolls around.
The findings, published in the Proceedings of the National Academy of Sciences USA, suggest that females in some species(3)_____ have evolved to play a critical role in their sons’ reproductive (4)_____. Karen Strier, the paper’s lead author and a professor at the University of Wisconsin-Madison, says the paper "(5)_____" the so-called grandmother hypothesis, a concept(6)_____ human females evolved to live past their(7)_____ reproductive years to spend more time(8)_____ offspring.
The research team observed and(9)_____ genetic data from a group of 67 wild monkeys living in a protected reserve in Brazil’s Atlantic Forest: infants, mothers and possible fathers. They found that six out of the thirteen(10)_____ males they studied spent more time around their mothers (11)_____ would be expected by chance. These same six monkeys, on(12)______, reproduced the greatest number of offspring.
The investigators are still trying to(13)_____ out why. "It’s not until we see moms intervening and helping their sons out," Strier says. "Maybe (14)_____ sitting near their moms, they get to see when females are(15)_____ active, or maybe they just get more familiar with other(16)_____."
The findings can(17)_____ with future conservation efforts for the critically(18)_____ animals. Strier says, "the(19)_____ thing we would want to do is(20)_____ a male out of the group where it was born." [br] (7)

选项 A、early
B、late
C、prime
D、entire

答案 C

解析此处需要填入修饰reproductive years(生育期)的词。生育期有很多年，而此处要表达女性在生育期之后花时间在后代上，即她们寿命延长了，由此可排除early。而late和entire用在此处都可表达活过了整个生育期，可同时排除。prime指“主要的”，可形容最佳的一段时期，合乎逻辑。
