标题: 求助一条 OG prep [打印本页] 作者: sandraqiuoffer 时间: 2017-9-26 03:14 标题: 求助一条 OG prep The heavy traffic in Masana is a growing drain on the city's economy——the clogging of the streets of the central business district alone cost the economy more than $1.2 billion over the past year. In order to address this problem, officials plan to introduce congestion pricing, by which drivers would pay to enter the city’s most heavily trafficked areas during the busiest times of the day.
Which of the following, if true, would most strongly indicate that the plan will be a success?
AApproximately one-fifth of the vehicles in the central business district are in transit from one side of the city to the other.
BPlanners expect that, without congestion pricing, traffic in Masana is likely to grow by 6 percent in the next five years.
CIn other urban areas, congestion pricing has strongly encouraged carpooling (sharing of rides by private commuters).
DSeveral studies have shown that a reduction in traffic of 15 percent in Masana could result in 5,500 or more new jobs.
EOver 30 percent of the vehicles in the city’s center are occupied by more than one person.
OA 是C，但是我不能理解为什么在其他城市有效，就说明会在Masana有效呢？对我来说这个选项不够直接啊。 求解释， 感谢！
