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 .
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 ?.

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

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

Efforts to explain how the pterosaurs became air-
borne have led to suggestions that they launched them-
selves by jumping from cliffs, by dropping from trees.
(45) or even by rising into light winds from the crests of
waves.

you can see here that the prior belief about P was they lived around water bodies(waves is the clue here). Though i understand that even winds have waves, in fact each physical thing has waves but out of all options, this is the only deductive answer. According to me this is a poor question by GMAT

Hi gmatexam439

I got all but 1 question wrong in the passage. I got the Question # 1 wrong. I chose C, but the right answer is D.

Hi, can anyone please help with Q5. Even though A is convincing, the line in the passage - Their skulls, pelvises, and hind feet are reptilian. The anatomy of their wings suggests that they did not evolve into the class of birds. - clearly suggests D. Where am I going wrong in reasoning?

Please explain Q5. It is written no where that they used to fold their wings.

GMATNinja GMATNinjaTwo,

Hi GMATNinja,

Could you please explain how option A is correct for Q7? The last paragraph tells us that "Pterosaurs became air-
borne by rising into light winds from the crests of waves". My main confusion is how can we deduce that the "waves" specifically mentioned here are from ocean waves? I was assuming that the waves were being referred to as the air waves instead.
