SEEING your verbal score, you seems to me are not native English speaker. However, the strategy that suits for me may not for you. So whether one rc should be escape or time should be taken much for long rc and moderate time for short rc depends on you. if you are in a hustle for rushing the next question within the time but get maximum wrong answers so it is effortless. But if you have to sacrfice some questions or by guessing answer to correct maximum possible questions that may not be worse, i think. All the answers options of the rc questions are twisted in the passage so you must understand for the complexity. SAY FOR EXAMPLE I AM SHOWING THE FACT.............TAKE THIS ONE AS A LEARNING

RC begins explanatory idea immediate following general idea preceded by the author at the top the first paragraph, then introduce exemplary example or supporting defending or offending idea that is tried by the author to make the preceding position strong, and the last phase of RC, author tries to take a position ( not necessarily in all passage) in relation to the summation of the main idea. so you can diagram
this in a way that follows----

introduction: GENERAL IDEA
then
body part: SUPPORTING OR OPPOSING STATEMENT
THEN
body part along with example: EXAMPLARY EXPLANATION
and finale
conclusion (not necessarily in all passage so far i know): AUTHOR’S POSITION REGARDING total explanation of the rc

YOU must know the trigger word to identify the turning or shifting point that the author directing the general idea toward WHAT?
Say for example BUT , ALTHOUGH, HOWEVER AND ..............
U have to know the similar or dissimilar introducing idea indicators say for example: by the same token, likewise............
and finally the author's TONE POINT: I GIVE YOU AN EXAMPLE THEN YOU WILL BE MUCH COMFORTABLE

NOW THE RC:



Although many lines of evidence indicate that birds evolved from ground-dwelling theropod dinosaurs, some scientists remain unconvinced. They argue that theropods appeared too late to have given rise to birds, noting that Archaeopteryx lithographica—the oldest known bird—appears in the fossil record about 150 million years ago, whereas the fossil remains of various nonavian maniraptor theropods—the closest known relatives of birds—date only to about 115 million years ago.But investigators have now uncovered bones that evidently belong to nonavian maniraptors dating to the time of Archaeopteryx. In any case, failure to find fossils of a predicted kind does not rule out their existence in an undiscovered deposit. Skeptics also argue that the fused clavicles (the “wishbone”) of birds differ from the unfused clavicles of theropods. This objection was reasonable when only early theropod clavicles had been discovered, but fossilized theropod clavicles that look just like the wishbone of Archaeopteryx have now been unearthed. Finally, some scientists argue that the complex lungs of birds could not have evolved from theropod lungs, an assertion that cannot be supported or falsified at the moment, because no fossil lungs are preserved in the paleontological record.



The primary purpose of the passage is to

a. compare the development of two hypotheses concerning the evolutionary origin of birds
b. suggest revisions to the standard theory of the evolutionary history of birds
c. evaluate the usefulness of fossil evidence in determining the evolutionary history of birds
d. challenge the theory that birds evolved from ground-dwelling theropod dinosaurs
e. respond to criticisms of the theory that birds evolved from ground-dwelling theropod dinosaurs

INTRODUCTION OR MAIN IDEA: "some scientists remain unconvinced" ANOW SOME SPEECH BEFORE AND AFTER THE MAIN IDEA. NO MATTAR...........

BODY PART: ATUTHOR’S OPPOSING POINT OR RESPOSE -1:But investigators have now uncovered bones that evidently belong to nonavian maniraptors dating to the time of Archaeopteryx.
SUPPOTING POINT TO THE OPPOSING POINT: In any case, failure to find fossils of a predicted kind ................AND

BODY PART: ATUTHOR’S OPPOSING POINT OR RESPOSE -2: This objection was reasonable when only early theropod.........................


CONCLUSION: THE SUMMATION OF THESIS: an assertion that cannot be supported or falsified at the moment----------

(-ASSERTION MEANS-complex lungs of birds could not have evolved from theropod lungs FOR no fossil lungs are preserved in the paleontological record. )---------HERE IF YOU have clear idea about CR premise -premise and conclusion then you will find it much relax the strong or weak position of the author. Here -----FOR no fossil lungs are preserved in the paleontological record. RESULT:complex lungs of birds could not have evolved from theropod lungs AND SUMMATION:an assertion that cannot be supported or falsified at the moment- HA HA HA HERE AUTHOR DOESNOT TAKE STRONG POSITION RATHER TAKES THE SUMMATION OF THE FINDINGS.


NOW QUESTIONS:


The primary purpose of the passage is to



a. compare the development of two hypotheses concerning the evolutionary origin of birds: IT IS ALMOST WRONG IN RC EXCEPT SOME ISSUES there are more theory about this on online u can easily find.

b. suggest revisions to the standard theory of the evolutionary history of birds: AUTHOR DOESNOT offer any plan to alter or edit the existing plan....

c. evaluate the usefulness of fossil evidence in determining the evolutionary history of birds: the evaluate means author must give the positive negative consequences of the general idear and takes one of them so nothing happened for evaluating.

d. Challenge the theory that birds evolved from ground-dwelling theropod dinosaurs; challenge means call into doubt, call into question, counteract, and contradicts to the concerning statement. ASAD have u identified any tone like these in this RC?, I DID NOT find you may not find i think to be.

e.. Respond to criticisms of the theory that birds evolved from ground-dwelling theropod dinosaurs

for: But investigators have now uncovered bones that evidently belong to nonavian maniraptors dating to the time of Archaeopteryx.
Author’s response: In any case, failure to find fossils of a predicted kind .............
author's response:This objection was reasonable when only early theropod.
- Final response: FOR no fossil lungs are preserved in the paleontological record. RESULT:complex lungs of birds could not have evolved from theropod lungs ,an assertion that cannot be supported or falsified at the moment



Ami mone kori apni dhaka theke likcen. as banglee we need to know more about gmat twist. so don't be frustrated. SO ami bolbo apni kokhono guess korben na just try to relate the intended meanning to the question. PRACTISE MORE QUESTION. I know as bangladeshi u r under 80% changes to do unofficially questions, which direct you in a wrong way. so man go ahead with full speed.aminfromuttara---------got it?

Have you tried reading regular books? Go to Nilkhet, buy onek ta classics (Sidney Sheldon marka boi cholbe na), learn how to read and understand efficiently, TARPOR try GMAT questions.

Trying GMAT RC/CR passages without having a solid grip on reading is like applying to BUET without knowing any math.
