Can someone explain the reason for following answers

5-A
7-A

both do not make any sense to me.

I got 5-A because B & D are specifically discounted in the text, and there is no mention of prey or forests to support C & E. The text "...and with it the wing, could only turn upward..." could be argued to support A, although I admit I found it a bit vague.

I got 7-A because of the theories mentioned in the last paragraph (they might take flight via cliffs or waves; both suggest water).

Please post the answers for any of the question posted on this forum.

Thanks in advance!!!!!!!!

Answer to 7 should be E "consumed twice their weight daily to maintain their body temperature", I am not sure why "lived near large bodies of water" is a better choice.

Answer to 5, D can't it be inferred "They were an early stage in the evolution of the birds." , in comparing its bones.
though I must agree that A is also as close and on another day I could have picked A.

I got this question 7 wrong when I was doing it initially.

But after re-reading the passage with the knowledge of the answer, my guess is that it has to do with this sentence:

"Efforts to explain how the pterosaurs became airborne have led to suggestions that they launched themselves by jumping from cliffs, by dropping from trees, or even by rising into light winds from the crests of waves. "

This point in the passage illustrates that the Pterosaurs could be living near water, using light wind from crest of waves to lift them to flight.

Can someone explain 5 and 7. Still dont get it.

Thats the answer to 5, now down to 7. Can some one exl. 7?

7. It can be inferred from the passage that some scientists believe that pterosaurs
(A) lived near large bodies of water
(B) had sharp teeth for tearing food
(C) were attacked and eaten by larger reptiles
(D) had longer tails than many birds
(E) consumed twice their weight daily to maintain their body temperature

Options BC & D aint specified or even remotely discused in the passage. As a matter of fact, even Option E aint discussed. In anycase, no line/sentence implies the frequency or magnitude of consumption.

Option A is ambiguous too. But its the closest option beacuse of the reasons mentioned by yeahdisk and lukester.
