题目材料：

Female Australian Dunatothrips [small, sap-sucking insects] create tent-like structures on the surface of leaves to protect themselves and their eggs and larvae from desiccation in the arid Australian climate. Bono and Crespi compared survival and reproduction of thrips that founded structures alone with those in groups of two or more individuals. They found that although per capita egg production fell with increasing group size, foundresses were more likely to survive and lay eggs in groups than when alone. Several studies of other species of nest-building insects have concluded that foundress associations are beneficial to all parties. It is likely that the relative success of groups is at least in part accounted for by a reduction of energy use in the modification of a shared nest.

The author would most likely agree with which of the following claims about Australian Dunatothrips?

A.Their offspring survival rates increase when larger groups cooperate to modify nests.
B.Their effect on the leaves used to support their tent-like structures is not necessarily permanent.
C.They expend as much energy to create tent-like structures as they do to produce broods.
D.They exhibit an effect from collective activity that is also found in certain other insect species.
E.They modify nests in different ways depending on what other species are present in their vicinity.
