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 advertisment's argument?
(A) The number of automobiles built by Deluxe each year has not increased sharply since 1970.
(B) Since 1970, Deluxe has made fewer changes in the automobiles it manufactures than other car companies have made in their auromobiles.
请大家指教^^
答案是B吧。如果公司对汽车进行了较少的改进,说明公司汽车的寿命长是因为最初的质量好,而不是因为频繁的维修保养导致的。
题目比较的是比例,而不是绝对数量。所以1970年以后的产量如何变化与本题没有关系。
我也以为是A,70年以后造的车的数量没有显著增长,说明现在路上车多不是靠70以后多造来支持的,是因为great durability
答案给的是A。但是题目里讨论的是rate:“half of all automobiles ”,而不是quantity。如果题目给出的证据是现役一个品牌的车的数量多于其他品牌,那么是不恰当的,我理解你的解释比较适合这种情况^^
