问题     A recent study, published in last week’s Journal of the American Medical Association, offers a picture of how risky it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal accident as a teenager driving alone. By contrast, the risk of death for drivers between 30 and 59 decreases with each additional passenger.
The authors also found that the death rates for teenage drivers increased dramatically after 10 p.m., and especially after midnight, with passengers in the car, the driver was even more likely to die in a late-night accident
    Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with "really stupid behavior" than with just a lack of driving experience. "The basic issue," He says, "is that adults who are responsible for issuing licenses fail to recognize how complex and skilled a task driving is. "
    Both he and the author of the study believe that the way to mitigate (使......缓解) the problem is to have states institute so-called graduated licensing systems, in which getting a license is a multistage process. A graduated license requires that a teenager first prove himself capable of driving in the presence of an adult, followed by a period of driving with night of passenger restrictions, before graduating to full driving privileges.
    Graduated licensing systems have reduced teenage driver crashes, according to recent studies. About half of the states now have some sort of graduated licensing system in place, but only 10 of those states have restrictions on passengers. California is the strictest, with a novice (新手) driver prohibited from carrying any passenger under 20 (with-out the presence of an adult over 25) for the first six months. (311 words)
A suggested measure to be taken to reduce teenagers’ driving accidents is that
选项 A、driving in the presence of an adult should be made a rule
B、they should be prohibited from taking on passengers
C、they should not be allowed to drive after 10 p.m.
D、the licensing system should be improved
答案D
解析 本题属于事实细节题。从第四段可知，研究者设立了一种新的具有约束性的执照发放体系，即经过重重考验之后，未成年人才可获得驾车的所有权利。对应选项应为D。对于A、B、C所说的几条建议，在最后两段介绍的建议中都只字未提，所以不应选择。
