Enforcement of local speed limits through police monitoring has proven unsuccessful in the town of Ardane. In many nearby towns, speed humps(raised areas of pavement placed across residential streets, about 300 feet apart)have reduced traffic speeds on residential streets by 20 to 25 percent. In order to reduce traffic speed and thereby enhance safety residential neighborhoods, Ardane's transportation commission plans to install multiple speed humps in those neighborhoods.
Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?
A. On residential streets without speed humps, many vehicles travel at speeds more than 25 percent above the posted speed limit.
B. Because of their high weight, emergency vehicles such as fire trucks and ambulances must slow almost to a stop at speed humps
C. The residential speed limit in Ardane is higher than that of the nearby towns where speed humps were installed.
D. Motorists who are not familiar with the streets in Ardane's residential districts would be likely to encounter the speed humps unawares unless warned by signs and painted indicators
E. Bicyclists generally prefer that speed humps be constructed so as to leave a space on the side of the road where bicycles can travel without going over the humps

A、沒有減速帶的地方，很多車超速25%，說明減速帶重要，作用相反。
B、因為重量大，消防車和救護車在減速帶這里幾乎要停，不利于保障社區(qū)安全，正確。
C、A地居民區(qū)限速比附近城鎮(zhèn)限得更多，不同地區(qū)限速高低比較，無關(guān)比較。
D、開車的人如果不熟悉A地居民區(qū)，就要看著指示牌才會意識到前面會有減速帶，與安全無關(guān)。
E、騎車的人希望減速帶留條縫，這樣騎車不用穿過減速帶，與安全無關(guān)。

Because the sudden freezing kills bacteria, QuickFreeze is planning to market a wastewater purification system that works on the same principle. The process works only when temperatures are cold, however, so municipalities using it will still need to maintain a conventional system. Which of the following, if true, provides the strongest grounds for a prediction that municipalities will buy QuickFreeze's purification system despite the need to maintain a conventional purification system as well?
