24-37 Fish currently costs about the same at seafood stores throughout
Eastville and its surrounding suburbs. Seafood stores buy fish from the
same wholesalers and at the same prices, and other business expenses
have also been about the same. But new tax breaks will substantially lower
the cost of doing business within the city. Therefore, in the future, profit
margins will be higher at seafood stores within the city than at suburban
seafood stores.
For the purpose of evaluating the argument, it would be most useful to know
whether
A) more fish wholesalers are located within the city than in the surroundingsuburbs.
B) any people who currently own seafood stores in the suburbs surrounding
Eastville will relocate their businesses nearer to the city
C) the wholesale price of fish is likely to fall in the future
D) fish has always cost about the same at seafood stores throughout Eastville
and its surrounding suburbs.
E) Seafood stores within the city will in the future set prices that are lower than
those at suburban seafood stores.

If the overall cost of doing business decilned, to keep higher margin, it would be reasonablly stay the price at original level instead decrease similarly. Then E.

The aricle has already told you the cost of fish is always the same. Why should make fuss to ensure it again ?

BTW , the cost of fish is included in the overall cost, not the same to it.
