问题
Most archaeologists have held that people first reached the Americas less than 20,000 years ago by crossing a land bridge into North America. But recent discoveries of human shelters in South America dating from 32,000 years ago have led researchers to speculate that people arrived in South America first, after voyaging across the Pacific, and then spread northward. Which of the following, if it were discovered, would be pertinent evidence against the speculation above?
选项
A、A rock shelter near Pittsburgh, Pennsylvania, contains evidence of use by human beings 19,000 years ago.
B、Some North American sites of human habitation predate any sites found in South America.
C、The climate is warmer at the 32, 000-year-old South American site than at the oldest known North American site.
D、The site in South America that was occupied 32,000 years ago was continuously occupied until 6,000 years ago.
E、The last Ice Age, between 11,500 and 20,000 years ago, considerably lowered worldwide sea levels.
答案
C
解析
短文得出结论,市长公开宣传活动说服人们乘公共汽车去上班而不是开车去,并且它把早上汽车流量的减少和进入市中心地区公共汽车乘客的增加引为证据。但(C)中描述的道路翻修为这个证据提出一个替代性的解释。因此(C)是正确答案;选项(A)排除了更低的票价作为乘客增加的一种可能的解释,因此它支持而不是质疑该结论;同样地(D)和(E)都排除了一种可能的解释:(D)中公共汽车数量未变和(E)中长期的公共汽车乘客的态度表明乘客的增加不能用服务改善来解释;(B)中提到的,市长乘坐公共汽车,可能有助于公开宣传活动的效果,但同评价该宣传活动是否使乘客增加无关。
