remain concerned about the prospect of inflation, although there are few signs of increasing energy prices driving up the cost of other goods so far. remain concerned about the prospect of inflation, although there are few signs of increasing energy prices driving up the cost of other goods so far
still remain concerned about the prospects of inflation; there are as yet few signs that increasing energy prices are currently driving up the cost of other goods
remain concerned about the prospect for inflation, even though as yet few signs of higher energy prices are driving up the cost of other goods so far
still remain concerned about inflation, even though there are currently few signs that increasing energy prices drive up the cost of other goods
remain concerned about the prospect of inflation, despite the lack of signs thus far that increasing energy prices are driving up the cost of other goods
Responding to a pm:
"prospect of inflation" means "possibility of inflation"
"prospects of" means "chances/ expectations, usually of success"
So policy makers remain concerned about the prospect (possibility) of inflation. 'Remain concerned about inflation' would not be accurate since there is a possibility of inflation (there are few signs hence inflation isn't actually taking place). Hence (B) and (D) are out.
(B) uses a semi colon and hence the sentence misses out on the contrast "...remain concerned, although/even though/despite..."
In option (A), placement of 'so far' makes it ambiguous. There are few signs so far OR ...driving up cost so far...
Also, in (A), "there are few signs of increasing energy prices driving up the cost ..." is incorrect structure.
"of + noun + ing" verb is correct only if "of + noun" makes perfect sense (not very common).
I have a video of a cat playing the piano. - video is of the cat so this sentence is correct.
There are few signs of increasing energy prices driving up the cost of other goods. - the few signs are not of energy prices but of energy prices driving up the cost of goods. Hence, this structure is not correct.
(C) is obviously incorrect "few signs of higher energy prices are driving up the cost of other goods" - illogical
Hence correct answer is (E). It uses 'prospect of inflation', places 'thus far' correctly - "lack of signs thus far that..."
