单选题 An advertisement designed to convince readers of the great durability of automobiles manufactured by the Deluxe Motor Car Company cites as evidence the fact that over half of all automobiles built by the company since 1970 are still on the road today, compared to no more than a third for any other manufacturer.
Which of the following, if true, most strongly supports the advertisement's argument?

A、 After taking inflation into account, a new Deluxe automobile costs only slightly more than a new model did in 1970.
B、 The number of automobiles built by Deluxe each year has not increased sharply since 1970.
C、 Owners of Deluxe automobiles typically keep their cars well maintained.
D、 Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their automobiles.
E、 (E) Deluxe automobiles have been selling at relatively stable prices in recent years.

【正确答案】 B

【答案解析】[解析] 本题段落推理是从一个数字比较中得出Deluxe汽车公司制造的汽车耐用。现在要支持它，那么也应从数字入手。(B)涉及数字，并且说明1970年以来，由Deluxe生产的汽车数量无急剧上升，从而说明近几年来其卖的车和别的公司差不多，但其汽车仍有超过一半跑在路上，所以其汽车耐用。所以(B)起到了支持作用，因此(B)正确；(A)、(E)谈的是价格，与数量无关；(C)说明是人的因素而非车的因素，起到了反对作用；而(D)离结论的距离比较远。
