GRE阅读 昆虫帮助苏铁传粉最后一道阅读题解析

阅读原文：Experiments show that insects can function as pollinators
of cycads, rare, palmlike tropical plants. Furthermore,
cycads removed from their native habitats—and therefore
from insects native to those habitats—are usually infertile.
. 1point 3acres Nevertheless, anecdotal reports of wind pollination in
cycads cannot be ignored. The structure of cycads male
cones is quite consistent with the wind dispersal of pollen,
clouds of which are released from some of the larger cones.
The male cone of Cycas circinalis, for example, sheds
almost 100 cubic centimeters of pollen, most of which is
probably dispersed by wind. Furthermore, the structure of
most female cycad cones seems inconsistent with direct
pollination by wind. Only in the Cycas genus are the
females' ovules accessible to airborne pollen, since only in
this genus are the ovules surrounded by a loose aggregation
of megasporophylls rather than by a tight cone.

7. The evidence in favor of insect pollination of cycads presented in the second sentence would be more convincing if which of the following were also true? (A) Only a small variety of cycad species can be successfully transplanted. (B) Cycads can sometimes be pollinated by means other than wind or insects. (C) Insects indigenous to regions to which cycads are transplanted sometimes feed on cycads. (D) Winds in the areas to which cycads are usually transplanted are similar to winds in cycads' native habitats. (E) The transplantation of cycads from one region to another usually involves the accidental removal and introduction of insects as well.

问题是指下列哪一项正确更能佐证苏铁是通过昆虫传粉的，那么正确答案应该是D才对，为什么选择E？
看了网上很多同质化的解析依然不明白，求解答~

为什么想选 D, D 不是佐证风的传播吗.

E 是苏铁的转移经常有昆虫的参与  怎么看都是一眼 E 啊

没考过gre的我乍一看还以为谁叫苏铁传。。。
