[語文] OG-CR-89
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～
