I would go with E. In D, "remains in this way" is a bit awkward.

As for "although" and "even when", the idea being expressed is that the carbon remains a diamond even in the absence of the conditions that caused the chance. By saying "although heat and pressure are removed", it makes it sound like that is a definite event. I don't think we can guarantee that.

This is a good example of when using the difference between the two "best" answers in your own sentence can help:

"The successful GMAT student stays calm even when confronted with confusing questions."

"The successful GMAT student stays calm although confronted with confusing questions."

Hello Bill thank you for the explanation... I have one doubt still in my mind.. Can i say that " ALTHOUGH signals that something is going to come"
eg: ALTHOUGH <this>, <that happened>
where as the above sentence <that happened> is missing.... Is my understanding correct????...

Right. "Although" is typically used to draw a contrast.

"Although normally docile, elephants in captivity have been known to attack their trainers."

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


Yes Bill is correct. The answer should be E and not D. Between D and E, it is a bit difficult to choose as both are very close. But when you understand the meaning of the sentence, you can easily choose the answer to be E and not D.

E is something like Not only X but also Y.

D is a complete contrast.

Eg: Let us take another sentence as a good example.

In business a particular strategy worked for the organisation in all the different conditions or situations and it worked in aggressive condition as well.

So this is not a contrasting sentence to permit the use of 'although'.

Even when has a lot of peers such as: still, moreover, not only...but also, also, as well etc...

It is adding to something and not contrasting to something...


Hope this helps...

This question tested Parallelism ; Meaning and Idioms (somewhere). Idiomatic construction is sometimes dependent on the meaning of the sentence, at least this sentence clearly means that...
