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.
A software company plans to develop new open-source software, which will be created online through the volunteer efforts of any interested programmers. Although the software will be free for anyone to use, the company predicts that it will nonetheless boost profits, since it will, cost almost nothing to develop and will improve the company's status in the eyes of customers in the market for its other software.
一个公司开发新软件，放在网上可以免费使用，因为这个软件开发也不花钱，同时可以提升公司在消费者眼中的地位，这个公司预测这免费软件会增加他们的利润
Which of the following, if true, would most help to support the company’s prediction about the effects of implementing the plan?
(A) Most customers in the market for the kinds of software the company makes prefer to buy from companies that make open-source software. 顾客更愿意购买这个免费软件公司的产品，免费软件——增加利润，正确
(B) The company has already improved its status among programmers by developing a variety of other open-source software. 无关
(C) The company should endeavor to improve its status and name recognition in the eyes of customers in the market for the kinds of software it makes. 无关
(D) The company's profits are currently growing, and it has high status in the eyes of its customers.
(E) Many software customers would prefer to use free open-source software rather than pay for commercial software products. 顾客用了免费软件但不愿意买产品，削弱
B A
