could not understand the OA: A

I think my confusion is failing to understand the suble difference b/w A and C -- where in A, it is hypothesis versus in C, it is an explanation challenged by author. I chose C -- since its seems like an explanation

Clearly A..

Using POE

B--> plogist suggests 2nd he is not opposing it
C--> plogist i supporting 1st not challenging it
D --> first is the conclusion of the plogist not the judgement advanced in support of it

planktons suffered a major population decline because of lower surface temp and many bottom dwellers depended on planktons...therefore cold caused this decline indirectly....only choice A fits into this pattern....

E--> 2nd is not an exceptional case....

Classic example of a Cause Effect situation:

Effect: The Botton-dweller probably died of the cold temperature indirectly
Cause: They had no food - the plantons died of the cold temperature.

Now one thing to note is that the effect here is a hypotheses because of the word "probably"....

So i pick A

This is clear A.
Look what Ps are trying to say.

You will circle out to A and B.
B says second BF is opposing Ps' point but its not so A.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
