I used the process elimination for question 7, took a lot of re-glancing through the passage:
7. It can be inferred from the passage that some scientists believe that pterosaurs
(B) had sharp teeth for tearing food: No mention of their teeth in the passage
(C) were attacked and eaten by larger reptiles: No mention of pterosaur being prey to a specific predator
(D) had longer tails than many birds: Initially thought this was the correct ans, but glanced through the passage and no mention of pterosaurs tail as compared to birds
(E) consumed twice their weight daily to maintain their body temperature: This one is tricky too, passage does mention that pterosaurs were warm blooded, but Huxley does give a hypothesis for the same with no mention of pterosaurs feeding habit.

(A) lived near large bodies of water : By process of elimination, this is what I GUESSED and also thet fact that "high waves to channel updrafts" was mentioned towards the end of the passage. Very tricky to be a confident YES.

Took 12 mins and got 5/7.

Takeaway - In RC which involve lot of specific details, just get the overall structure and essence of each question and then get into specifics basis the question.

In the real GMAT we would have around 4 questions per RC... so definitely some details would never be asked in the question and hence a waste!!!

Took 14 min hell of a time .
My answers are
D B C B E E B A

Can someone explain me what's wrong with 5th question ? what's wrong with A - as it can also inferred as they said can't fold when landing on trees - implies live on trees aka forest areas ?.

Thanks in advance

I would like an explanation too. the only relevant part that would suggest the answer is A is "The anatomy of their wings suggests that they did not evolve into the class of birds." but this seems like quiet the inference

Answer to your question lies in this line of last para:
The second hypothesis seems unlikely because large pterosaurs could not have landed in trees without damaging their wings

(A) They were unable to fold their wings when not in use.

Landing on trees means non usage of wings.
Since pterosaurs can NOT fold their wings, they end up damaging the same.

basically for #7 if you don't know what "crest of waves" means you get it wrong.

I picked (A) because I thought reptiles have sharp teeth and I honestly thought the waves mentioned in the last paragraph were meant to be air waves
