Mayor: Since the time that our city's central streetcar line was built ten years ago, over $4 billion of private development has occurred within one-half kilometer of the line. This private development increased the city's tax revenue over those ten years just enough to compensate for the cost of building that line. So our city's proposed development of an eastside streetcar line through a similar neighborhood should also pay for itself within ten years.城市中心修了一条路，吸引了很多个人商业发展，这些发展提高了城市税收，在十年内就弥补了修路的钱。所以城市在东边再修一条路也会在十年内回本。
Which of the following is an assumption the mayor's argument requires?
A. Over the past ten years, private developers have invested in significant development within one-half kilometer of the proposed eastside streetcar route.
B. Little if any of the private development referred to would have occurred if the streetcar line had not been built. 如果不修路就不会有发展，取反如果不修路也会有发展，那就削弱了修路会回本这一结论
C. One benefit to the city from the central streetcar line has been the increased tax revenue from private development in other parts of the city.
D. Less than $4 Billion of private development has occurred more than one-half kilometer from the central streetcar line over the past ten years.
E. The central streetcar line did not cost the city significantly more to build than the eastside streetcar line will cost.
