will go with option C

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.

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?" "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.

(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.
