2. It can be inferred from the passage that the author believes which of the following to be true of the environmentalists mentioned in lines 5-6?

(A) They have wrongly chosen to focus on anecdotal reports rather than on the long-term data that are currently available concerning amphibians.
(B) Their recommendations are flawed because their research focuses too narrowly on a single category of animal species.
(C) Their certainty that population declines in general are caused by environmental degradation is not warranted.
(D) They have drawn premature conclusions concerning a crisis in amphibian populations from recent reports of declines.
(E) They have overestimated the effects of chance events on trends in amphibian populations.

Dear GMATNinja GMATNinjaTwo Sajjad1994
I have a query on question 5. Why D is wrong?
From my understanding, The passage tells about the phenomenon : (The decrease in population and extinction of amphibian) then It shows 2 views from this phenomenon
1 is from environmentalist
2 is from biologist
The view 1 is rejected by the author in paragraph 2.

Please correct me, am I missing something?
Thank you!

can anyone tell me why in question 4 rarest=always rare.
I don't think that always rare means rarest. And "rarest" seems extreme,so I choose it.

GMATNinja, can you please explain why D should be eliminated for Q3?
It is noted in the 2nd par that chance events may lead to extinction.

Why Q2 C is incorrect?
2. It can be inferred from the passage that the author believes which of the following to be true of the environmentalists mentioned in lines 5-6?
(C) Their certainty that population declines in general are caused by environmental degradation is not warranted.
3rd and 4th para - The author believes that decline could be due to normal fluctuations. So the claims made by environmentalist that declines are caused by degradation is not certain. The author does not believe this claim. Why C is incorrect then?

Can anyone please help me with Q4 here ? I am not able to get the approach. It probably means that I have to take inference from multiple lines in all the paragraphs, but what is the best way to do so ? It is difficult for me to retain so much info at once.

Take a look at this post and let us know if you have further questions!

I have not completely understood the reason behind eliminating option C in question 2. Option C and option D look similar to me. It would be of great help if anyone could elaborate along these lines and clarify my doubt.

Thanks

Took me 13 mins 30 sec, 5 correct, 1 wrong.
Is this the optimum time for such a passage?
Any tips?

5. Which of the following most accurately describes the organization of the passage?

(A) A question is raised, a distinction regarding it is made, and the question is answered.
(B) An interpretation is presented, its soundness is examined, and a warning is given.
(C) A situation is described, its consequences are analyzed, and a prediction is made.
(D) Two interpretations of a phenomenon are described, and one of them is rejected as invalid.
(E) Two methods for analyzing a phenomenon are compared, and further study of the phenomenon is recommended.

from P2&3, the author compares declining population and endanger population. in P4, authors proposes long-time data, so I think E match.

what's the problem with my reasoning ?

thanks in advance.

About 4 minutes for the passage and 1 minute for each question, for a total of 10 minutes.
