The original sentence contains several errors. First, "less availability" is incorrect when not used in a direct comparison: it begs the question "Less than what?" "Decreased availability" would be better here. Second, "greater demand" also begs the question "greater than what?" "Increased demand" would be better. Third, "Demand for scientific research" implies that the research is in demand, when in fact it is the platinum. "Demand in scientific research" would be better. Fourth, "remains consistently expensive" is redundant. "Remains expesnive" would be enough to convey the idea.

The OA is C. Here is the explanation they have given:

The original sentence contains several errors. First, "less availability" is incorrect when not used in a direct comparison: it begs the question "Less than what?"

Third, "Demand for scientific research" implies that the research is in demand, when in fact it is the platinum. "Demand in scientific research" would be better. Fourth, "remains consistently expensive" is redundant. "Remains expesnive" would be enough to convey the idea.

(A) This choice is incorrect as it repeats the original sentence.

(B) This choice is incorrect because while it replaces the "greater demand" with "increased demand," it leaves "less availability." "Demand for scientific research" should be changed to "demand in." The redundancy of "consistently" remains, and a illogical comparison is drawn between platinum and "that of gold." It is unclear what the "that" refers to.

(C) CORRECT. This choice replaces "less availability" with "decreased availability" and "greater demand" with "increased demand." The word "consistently" is removed, and "demand for" is changed to "demand in."

(D) This choice incorrectly keeps "Demand for scientific research," which should be changed to "demand in scientific research"

(E) This choice is incorrect because, while it replaces the "less availability" with "decreased availability," it leaves "greater demand." "Remains at a consistently high price" is redundant. It is also more concise to compare the platinum to the gold, rather than the high price (of platinum) to "that of the gold" as is attempted in E.

@IEsailor ....I was just about to say that. Indeed, demand for changes the meaning.

So it is C.

The words "less" and "greater" are not suitable in this context. We have to denote the change in demand and availability with the words "increase" and "decrease" which are more appropriate in this context. Increase and decrease represent change over time which is exactly what's happening here.
Second error to look for is the use of wrong preposition. Instead of "...for scientific research..." the correct preposition is "...in scientific research...."

demand for is related to something material like his demand for a box of chocklates

demand in is related to something where the requirement is like 'demand in job

IMO, the question is not just about idiom or sound but more of meaning
or context.

"demand for Y" is correct much as is "demand in Y"

Platinium is increasingly used in scientific reasearch, and its availability is reducing.
Also, because price is usually proportional to supply (or availability, in this case), the cost of Platinum remains high.

Demand FOR Platinum (IN scientific research) is increasing, its availability is shrinking; the price, as a consequence remains high (just like gold)

The increasing demand is NOT for "scientific research." Rather, there is an increasing
demand FOR platinum IN scientific research.

This is what option (C) says, and we would agree that (D) changes meaning.

Please correct me where I am wrong.

I can always eliminate it to the last 2 but I always get it wrong. Thanks for the clarification.

Eliminate B and E as they have "like that of gold". You are doing a simple comparison between the two. Hence "that of" is unnecessary.

Among A, C and D eliminate A and D because they use "demand FOR". This is incorrect because that would imply that scientific research is in demand, not platinum itself.

Hence C remains.

Because of less availability and greater demand for scientific research, platinum remains consistently expensive, like gold.

-remains consistently is awkward A, B & E out
-platinum is compared to gold so -like is correctly used, (suppose the cost is compared than it would have been correct to use "that of" - B & E OUT

(A) Because of less availability and greater demand for scientific research, platinum remains consistently expensive, like gold.
(B) Because of less availability and increased demand for scientific research, platinum remains consistently expensive, like that of gold.
(C) Because of decreased availability and increased demand in scientific research, platinum remains expensive, like gold.

in scientific research is the correct form - correct

(D) Because of decreased availability and increased demand for scientific research, platinum remains expensive, like gold.
(E) Because of decreased availability and greater demand in scientific research, platinum remains at a consistently high price, like that of gold.

In choice(A), "less availability and greater demand" are not parallel.

Choice(C) with "decreased availability and greater demand" is correct

However, I am having concerns with "decreased availability". It sounds as if "someone" is reducing the availability of Platinum, while we want the sentence to mean that Platinum's availability is "low". Also, I was not sure why less was wrong. As far as I know, less can be used as both adjective and a comparative.

Hello Mike,
Would you be so kind as to take a look at the link above and tell me your take on this question.
thanks

Dear Sara,
I'm happy to help.

Overall, this seems like a solid question. I have no idea what the source is, but I like the splits, and it definitely has one unambiguously clear answer, the way a good SC question should. I don't know why they include "because of" in the underline, since it's identical in all five answers, but that's a niggling stylistic detail. The question itself is of very high quality.

Split #1: (less & greater) vs. (decreased & increased). This is really a false split. It's true, the former pair will be more widely applicable than the latter pair, because the latter pair is limited to instanced in which there has been a change in quantity over time, but apparently that's true here, so either is fine.
Split #2: demand for vs. demand in. This is a very clever idiom split. The phrasing "demand for scientific research" would mean that, overall, folks want more scientific research --- it doesn't matter the topic, the research area --- people just want more. That would be very non-specific, and would necessarily have a whole lot to do with platinum. The focus, the star, of the sentence is platinum. The "availability" is clearly the availability of platinum, so for logical consistency, it should also be a "demand" for platinum. The noun "scientific research" is NOT the thing demanded, but instead the context in which the platinum is demanded. Therefore, we must say "demand in scientific research", which implies that the demand is for platinum. The only answers consistent with this split are (C) and (E).
Split #3: the comparison with "gold" at the end. Three answers have "platinum remains consistently expensive, like gold," which is perfectly correct. Since there's no other noun in that clause, it's crystal clear that the comparison is between platinum and gold. Choice (B) has "platinum remains consistently expensive, like that of gold," which is logically incorrect --- we are comparing the metal platinum to what about gold???? Choice (E) has "platinum remains at a consistently high price, like that of gold" is grammatically & logically correct, but rhetorically unacceptable: it's a long, indirect, bulky way of saying something that can be said much more efficiently and succinctly, and in fact, is said that way in three other answer choices. Choice (B) & (E) cannot be correct.
On the basis of these splits, only (C) can be the correct answer. Choice (C) is mistake-free and elegant, and each of the other four answer choices has an unambiguous problem preventing it from being the answer. This is an an exceptionally good question. Kudos to whoever wrote it!!

Does all this make sense?
Mike

Because of Parallelism( decreased availability and increased demand) A, B, E are Eliminated.
Between C and D "demand in" is appropriate.

demand FOR scientific research means that scientific research itself is what's desired which is incorrect in this context, we are talking about the demand for platinum in scientific research.
Correct. Though it is an idiomatic usage not to be used much on GMAT now a days, I think it will be useful to share..
In any case, it boils down to understanding the idiomatic usage:
demand FOR X means that X itself is what's desired,
whereas
demand IN X means that something else is demanded to satisfy the interests of field/endeavor X
