Hello

I have decent accuracy in CR, however I face problems while solving high level CR questions mainly because while I am trying to understand the complicated question and then connecting the information to find the right answer, either i take too much time, or i just end up getting it wrong.

For example in a question like this
Although fullerenes - spherical molecules made entirely of carbon - were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite. Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes were formed.
Which of the following, if true, most seriously undermine the argument?

A. Confirming that the shungite genuinely contained fullerenes took careful experimentation
B. Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft
C. The mineral shungnite itself contains large amount of carbon, from which fullerenes apparently formed
D. The naturally occurring fullerenes are arranged in a previously unknown crystalline structure
E. Shungite itself is only formed under distinctive conditions

I took so much time to conclude that i need to find something which proves that naturally occurring fullerene and synthetic fullerene differ in their structure.

Someone please help me as to how can i understand complicated question stems and simplify the same in order to get the right answer.
I have 30 days to go for GMAT

Hi,

I am no way an expert, but here are my two cents:

Although fullerenes - spherical molecules made entirely of carbon - SOMETHING were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite. Since laboratory synthesis of fullerenes SOMETHING requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes SOMETHING were formed.
Which of the following, if true, most seriously undermine the argument?

So argument says that SOMETHING has been synthesized in lab but is now also found in nature. So, since formation of this SOMETHING requires distinctive conditions, geologist can now hypothesize, based on laboratory conditions, the condition of earths crust when this SOMETHING was formed.

We want to undermine the underlined conclusion
So possible ways we can undermine this conclusion is:
use some information to prove that based on given info in argument, geologist cannot hypothesize

A. Confirming that the shungite genuinely contained fullerenes took careful experimentation
B. Some fullerenes have also been found on the remains of a small meteorite that collided with a spacecraft
C. The mineral shungnite itself contains large amount of carbon, from which fullerenes apparently formed
D. The naturally occurring fullerenes are arranged in a previously unknown crystalline structure - CORRECT, as the structure of naturally occurring SOMETHING is PREVIOUSLY UNKNOWN, it must not match the conditions of the lab
E. Shungite itself is only formed under distinctive conditions

In difficult CR questions, I usually focus on the supposedly non important words: since, thus, hence, because ....and so on. Understanding the reasoning and the flow helps. Try not to get overwhelmed by the wordiness of the author.

All the best with your GMAT

Hi,

In addition to the above you could also just try a few things RON purewal advocates...

1)to simplify the argument explain the argument to a hypothetical 10 yr old(my take is=tell back to urself what u have just read.In the beginning this will take time but as time progresses it will come to you intuitively).Ron also says that this is the way to go about reading and understanding anything for that matter(simplify stuff and tell it to urself(or to a hypothetical 10 yr old)).

2)For me personally,i identify the conclusion and byheart it before going to the options.See if it works for you..

For more tips see rons videos.It will hardly take a week for you to do well in CR if you see his videos with interest.

All the best.1 month is more than sufficient to do well in CR..

Cheers

Hi Tanisha_shasha,

In a prior post, you noted that you were scheduled to take the GMAT on August 4th, 2018. How did you score on that Exam (including the Quant and Verbal Scaled Scores)? Since it's been over 5 months since that date, it would also help to know how you've been studying during that time:

1) What additional study materials have you used?
2) How have you scored on your practice CATs?
3) What is your retest date?
4) What are your current application plans?

GMAT assassins aren't born, they're made,
