While larger banks can afford to maintain their own data-processing operations, many smaller regional and community banks are finding that the cost associated with upgrading data-processing equipment and with the development and maintenance of new products and technical staff are prohibitive.
A. cost associated with
B. costs associated with
C. costs arising from
D. cost of
E. costs of
Idiom : associate with. Between A and B ,why A is wrong? "cost associated with upgrading data-processing equipment ",with the development and maintenance of new products and technical staff " are plural. It agrees with verb "are"
Piyatiwari alluded to this in his post, but just to clarify we choose "associated with"
not because of any
idiom issues. "Costs arising from" and "Costs of" are both idiomatically correct, and in fact "costs of" is even more concise than "costs associated with"!
What makes the difference here is
parallelism. We're discussing the costs in two categories: "data-processing equipment" and "development and maintenance of ..." Since the sentence has "and
with the development and maintenance ..." we should choose (B) because it is most parallel.
My take? Idioms are difficult (and rare), so think first about other issues.
