【OG20-696题】A moderately large city is redesigning its central downtown area and is considering a plan that would reduce the number of lanes for automobiles and trucks and increase those for bicycles and pedestrians. The intent is to attract more workers and shoppers to downtown businesses by making downtown easier to reach and more pleasant to move around in.
Which of the following would, if true, most strongly support the prediction that the plan would achieve its goal?
A People who make a habit of walking or bicycling whenever feasible derive significant health benefits from doing so.
B Most people who prefer to shop at suburban malls instead of downtown urban areas do so because parking is easier and cheaper at the former.
C Most people who own and frequently ride bicycles for recreational purposes live at a significant distance from downtown urban areas.
D If the proposed lane restrictions on drivers are rigorously enforced, more people will likely be attracted to downtown businesses than would otherwise be.
E In other moderately sized cities where measures were taken to make downtowns more accessible for walkers and cyclists, downtown businesses began to thrive.
正确答案：E
我最后DE二选一选了D，请问D为什么不可以？
还有一个类似的例子是og上的另一题
"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?
(A) Approximately one-fifth of the vehicles in the central business district are in transit from one side of the city to the other .
(B) Planners expect that, without congestion pricing, traffic in Masana is likely to grow by 6 percent in the next five years .
(C) In other urban areas, congestion pricing has strongly encouraged carpooling (sharing of rides by private commuters).
(D) Several studies have shown that a reduction in traffic of 15 percent in Masana could result in 5,500 or more new jobs.
(E) Over 30 percent of the vehicles in the city's center are occupied by more than one person"
如果你認為Ｄ為答案, 那你就是自行假設了 ” more people be attracted must be either workers or shoppers, or both, and they must be either pedestrians or bicyclist, or both "
