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


Could someone explain the difference between choice D and C ?

I do understand the " decreased availability and increased demand " usage

Thanks

Parallel Construction - Increased ... and Decreased ...

Because of less availability and greater demand for scientific research, platinum remains consistently expensive, like gold. [1. Greater requires comparison with other entity, 2. Less ... and greater - not parallel - eliminate it]

Because of less availability and increased demand for scientific research, platinum remains consistently expensive, like that of gold. [ less and increased - not parallel - eliminate it]

Because of decreased availability and increased demand in scientific research, platinum remains expensive, like gold. [Parallel sounds Ok but demand in is not correct idiom - eliminate it]

Because of decreased availability and increased demand for scientific research, platinum remains expensive, like gold. [Hold it]

Because of decreased availability and greater demand in scientific research, platinum remains at a consistently high price, like that of gold. [decreased and greater - not parallel]

six choices?

--

decreased means that something has come down from a previously higher value, while less means that you are comparing two contemporaneous quantities side-by-side (unless the 'less' construction contains explicit time markers, such as '...less than the previous value').
same goes for 'increased' vs. 'greater'.
