Networks of blood vessels in bats' wings serve only to disperse heat generated

in flight. This heat is generated only because bats flap their wings. Thus

paleontologists' recent discovery that the winged dinosaur Sandactylus had

similar networks of blood vessels in the skin of its wings provides evidence

for the hypothesis that Sandactylus flew by flapping its wings, not just by

gliding.



The argument in the passage relies on which of the following assumptions ?

(A) Sandactylus would not have had networks of blood vessels in the skin of

its wings if these networks were of no use to Sandactylus.


(E) Heat generated by Sandactylus in flapping its wings in flight could not

have been dispersed by anything other the blood vessels in its wings.


正確答案是A，但由於解答解釋的沒很清楚，我實在搞不清楚為何(E)不行？

想了很久不是很通，先謝謝強者了～

推 dddaaa:E 選項的第一句直接說了結果 但問題是要問這結果依賴的假設
→ dddaaa:Sandactylus 可能並不會拍翅膀飛翔
→ dddaaa:所以也不用anything other the blood vessels in its wings
→ dddaaa:不知道這樣說有沒有錯
→ ken22154:恩恩.....雖然還是不能完全理解，但感謝你的回答！
