graphite changes into
( X= the substance commonly referred to as diamond ) and .............

clearing the maze, the stem somewhat reduces to :

graphite CHANGES into X...........AND.........

for sake of parallelism what shld come after AND: guess REMAINS; thus A B C are chopped

bxn D n E :

D : remains in this way.........although heat is removed : some intutive thinking, diff to choose bxn even though n although; but IN THIS WAY ?????? IN WHAT WAY????? not very clear Eliminated

E : remains thus......................even though heat is removed : graphite changes to X and remains THUS ie in X form, clear n simple

A. remaining this way whether or not
B. remaining like that even as
C. remaining as such whether or not
D. remains in this way although
E. remains thus even when

Type : Parallelism - changes.....remains...Only two option (D & E) has this.

I have read in OG. "thus" is concise & better way to say "in this way". Therefore, E.

Hi Darmody,

Your question is very much justified; this usage of "thus" is rare. Usually it is used to mark a conclusion, but in this sentence it is used to express the present state of something; "in this way".

"Thus" is used in this sentence to expresses the present state of the transformed graphite, i.e. diamond.

To put it in simpler word you can replace "thus" with "in this way"

So the choice can be reworded as - remains in this way even

You may use "thus" as a replacement of "in this way" or "the same way"

As an example:

Mary is extremely sad and is expected to remain thus until she hears some good news. --> You may replace "thus" with "in this way" and the meaning would remain the same.

vercules,
Can you please explain why the use of although is wrong in this sentence...

Hi skamal7,

Putting into simple words, you use "although" when you are stating facts that happened or happening. "even when" is usually used when you want to express a hypothetical condition or a habit.

I go to school although it is raining.-->

Incorrect, "I go to school" expresses a habit, where as "although" is expressing a fact, i.e. "it is raining". The question under discussion presents the quality of graphite/ diamond. This is a general truth and in its use of although in (D) the sentence incorrectly means that this one time "heat and pressure are removed" and diamond remains in its current state. However, this does not expresses a general quality properly. The sentence's actual meaning is that diamond will retain its state while and even after removing heat and pressure. The removal of heat and pressure has not happened, it may or may not happen thus it is hypothetical. The use of "even if" would also be correct in this case.

I am going to school, although it is raining. -->

Correct, two facts are being expressed "going to school" and "it is raining".

I go to school even when it is raining. -->

Better, the sentence means that "I will go to school whether it rains or not" is it raining right not? may be or may not be (hypothetical).

I go to school even when it rains. -->

Best, now the sentence expresses a habit, using simple present verbs "go" and "rains".

Hope this helps,

Vercules

(C) remaining as such whether or not
(D) remains in this way although
(E) remains thus even when

The official answer to this problem is E!!!

Hi E-Gmat,

Under high pressure and intense heat, graphite, the most stable form of pure carbon, changes into the substance commonly referred to as diamond and remaining this way whether or not the heat and pressure are removed.

(A) remaining this way whether or not-out
(B) remaining like that even as-out
(C) remaining as such whether or not-out
(D) remains in this way although
(E) remains thus even when

Im able to eliminate Choices A,B,&C as and is the parallel marker First Verb is "Changes" and Second should be "Remains"
But not able to eliminate Choice D & E. Please explain ?

In D, 'this' doesn't have a referent. 'Although' is used to bring in contrast, which isn't required (and illogical too). Another thing. 'Although' is a conjunction (subordinate) and hence proper punctuation (comma) is needed to connect the main and dependent clauses.

E remains.

Hi Nitin,

As the above poster has pointed out "although" is unnecessarily bringing in a contrast. There is no contrast in the intended meaning of the sentence. The sentence wants to say that even when certain conditions are changed, the diamond doesn't change. So, no contrast is required here.

I hope this helps!

Regards,
Meghna

On OG12, the answer for this question is given as E. Over here, it is given as D.

I was relying on the latter all this time, and when I sat down to solve OG12 today, I realized the answer option "D" is incorrect. This has been so confusing for me. Can we please have correct answers on the questions over here. I am sure that will help a lot of people instead of creating ambiguity.

usually "thus" is used to mean roughly "therefore", BUT "thus" can mean "in the same way" or "in the same state".
for instance:
at maturity the caterpillar becomes a butterfly, and remains thus until its death. --> in this case, "thus" means "in the same state", and, therefore, means "as a butterfly".

same thing in choice (e), in which "thus" means "in the form of diamond".

this IS the intended meaning: AT THE TIME WHEN the pressure is removed, the substance stays in the form of diamond.

(d) is incorrect.

* "in this way" is unidiomatic here.
"in this way" can refer only to the MANNER IN WHICH AN EVENT OR ACTION OCCURS OR IS PERFORMED.
it CANNOT refer to the physical state of something. for instance, in the above example, you CANNOT use "in this way" to refer to the butterfly stage.

also:
* if you use "although", you are basically declaring that "the heat and pressure are removed".
in other words, "X, although Y" expresses the idea that X and Y are both facts (although they contrast with each other in some way).
this is not the intended meaning; "heat and pressure are removed" is a hypothetical that may or may not happen, and so should be introduced with "when" or "if" rather than "although".

-End of Ron's message

Thank you.

Hi,
In that case, please change the OA. Thanks.

Thank you.

agree with you on above things. D is not logic, using meaning analysis.

the problem to me is that "thus" in E is similar to "so"
"and remain so" would be easy for us.
but in the dictionary "thus" have no meaning of "so".

gmat want us to realize the illogic meaning in D and to choose a meaning of "thus" which is new to all of us.

in dictionary "thus" means "in this way"
if "thus" have only this meaning, D is wrong ONLY BECAUSE although is not so logic as when.

Two reasons for option E over D :

- D introduces unnecessary contrast by using Although. (Although changes the intended meaning of the sentence)

- In D (X, although Y) - the subject of X & Y are not related.
