Although we could replace the beautiful—but dilapidated—old bridge across Black River with a concrete skyway, we should instead replace it with a cable bridge even though this would be more expensive than building a concrete skyway. The extra cost is clearly justified by the importance of maintaining the beauty of our river crossing.
Which one of the following is an assumption on which the argument depends?
(A) It is no more costly to maintain a cable bridge than a concrete skyway.
(B) A concrete skyway would not have any practical advantages over a cable bridge.
(C) The beauty of the river crossing must be preserved.
(D) If the new cable bridge is built, most people who see it will think the extra money well spent.
(E) Building a cable bridge across Black River would produce a more aesthetically pleasing result than building a concrete skyway.
