CXD-Evaluation-全真9

9. Although compact cars make up only 38% of the vehicles in traffic, 48% of the cars that are followed too closely ("tailgated") are compact. On the other hand, fewer than 27% of the cars tailgated are middle-sized, even though middle-sized cars make up 31% of the vehicles in traffic.

Which of the following, if true, most contributes to an explanation for the phenomenon described above?

A) The shape of compact cars makes it easy for a tailgater to see far enough ahead around such cars to minimize the chances of a rear-end collision.

B) Middle-sized cars, owned by families with children and pets, are likely to have bumper stickers that are so interesting to read that tailgaters stay behind such cars longer.

Which one beween A and B, should be the answer?
