Deer, turkey, wild pigs, and bears also feed heavily on acorns, but do not store them,and are therefore of no benefit to the trees. Flying squirrels, chipmunks, and mice are also unlikely to promote tree dispersal--- whose behavior of caching (hiding) acorns below The leaf litter often promotes successful germination of acorns --- and perhaps blue jays,important long-distance dispersers, seem to help oaks spread and reproduce.

46. It can be inferred from paragraph that chipmunks do not aid in the dispersal of oak trees
because
A).they store their acorns where they cannot germinate
B). they consume most of their stored acorns
C). their stored acorns are located and consumed by other species
D). they cannot travel the long distance required for dispersal

The answer is A.How can I know it???

do not aid in the dispersal 对应unlikely to promote
所以原文破折号后解释就是答案。

“whose behavior of caching (hiding) acorns below The leaf litter often promotes successful germination of acorns”，我对这句话的理解是：他们把橡树果藏在树叶下的行为经常促进了橡树果的成功发芽生长。
无法支持答案A阿？
