Hey,

One way to manage time and read passages effectively is to read what is important and what is not because you can solve 80% of the passage by reading 20% of the passage.

All the very best.

Thanks,

Took a while to understand the structure.
My problem is if I do passages in person ( as in not part of a test) I am able to understand the structure and answer well.
However on mocks, I suffer from mental blockage of time constraint.

I genuinely feel I am running out of time while on test.
Can someone help me what should I do in such scenario?

I usually see how stupidly I mark answers to questions while on Mocks but while on customized quizzes or GMAT club timer,
I have a higher score for the same question ( I bet :P )

Hello Moderators and Experts GMATNinja sir, VeritasKarishma Ma'am,
Could you please help me whether the line of my reasoning is correct regarding Question no. 8:
It's pretty evident from the passage that option B is the answer, based on these lines:
Quote:
When molecular biologists discovered, more-
over, that such information cannot flow from
protein to protein, but only from nucleic acid to
protein, the theory that an antigen itself pro-
vided the mold that directed the synthesis of an
antibody had to be seriously qualified.

Regarding option A, the assumption is that
Antigen ( a foreign substance) attacks lymphocyte cells to produce antigens
But the cell-mediation process does not question this. It only explains how antigens react with Lymphocytes with new perspective.

This is the reason why option A is wrong.

Am I correct with my reasoning?

Regards,
Rishav
