Networksof blood vessels in bats’ wings serve only to disperse heat generated in flight.This heat is generated only because bats flap their wings. Thuspaleontologists’ recent discovery that the winged dinosaur Sandactylus hadsimilar networks of blood vessels in the skin of its wings provides evidencefor the hypothesis that Sandactylus flew by flapping its wings, not just bygliding.

Theargument in the passage relies on which of the following assumption?  A
Whichof the following, if ture, most weaken the argument above?  E

Thedesign of desperase heat are there necessary and only way to disperase when ananimal is flying


(A) Sandactylus would not have hadnetworks of blood vessels in the skin of its wings if these networks were of nouse to Sandactylus.  The design must has its own reason.
(B)  All creatures that fly byflapping their wings have networks of blood vessels in the skin of their wings.
(C)  Winged dinosaurs that flappedtheir wings in flight would have been able to fly more effectively than wingeddinosaurs that could only glide.
(D)  If Sandactylus flew by flappingits wings, then paleontologists would certainly be able to find some evidencethat it did so.

(E) Heat generated by Sandactylus inflapping its wings in flight could not have been dispersed by anything otherthan the blood vessels in its wings.  There is no other way to disperse the heat.

我想问问E哪里错了。
恐龙只有这一种排热方法——这是唯一的拍热方法——有这个拍热方法就一定是抖翅膀。  对么？ 这里面有什么trap求大NN解释一下
