问题     Joe Coyne slides into the driver’s seat, starts up the car and heads to town. The empty stretch of interstate gives way to urban congestion, and Coyne hits the brakes as a pedestrian suddenly crosses the street in front of him.
    But even if he hadn’t stopped in time, the woman would have been safe. She isn’t real. Neither is the town. And Coyne isn’t really driving. Coyne is demonstrating a computerized driving simulator that is helping researchers at Old Dominion University (ODU) examine how in-vehicle guidance systems affect the person behind the wheel.
    The researchers want to know if such systems, which give audible or written directions, are too distracting—or whether any distractions are offset by the benefits drivers get from having help finding their way in unfamiliar locations.
    "We’re looking at the performance and mental workload of drivers," said Caryl Baldwin, the assistant psychology professor leading the research, which involves measuring drivers’ reaction time and brain activity as they respond to auditory and visual cues.
    The researchers just completed a study of the mental workload involved in driving through different kinds of environments and heavy versus, light traffic. Preliminary results show that as people "get into more challenging driving situations, they don’t have any extra mental energy to respond to something else in the environment, "Baldwin said.
    But the tradeoffs could be worth it, she said. This next step is to test different ways of giving drivers navigational information and how those methods change the drivers’ mental workload.
    "Is it best if they see a picture…that shows their position, a map kind of display?" Baldwin questioned. "Is it best if they hear it?"
    Navigational systems now on the market give point-by-point directions that follow a prescribed mute. "They’re very unforgiving," Baldwin said. "If you miss a turn, they can almost seem to get angry."
    That style of directions also can be frustrating for people who prefer more general instructions. But such broad directions can confuse drivers who prefer route directions, Baldwin said.
    Perhaps manufacturers should allow drivers to choose the style of directions they want, or modify systems to present some information in a way that makes sense for people who prefer the survey style, she said.
    Interestingly, other research has shown that about 60 percent of men prefer the survey style, while 60 percent women prefer the route style, Baldwin said. This explains the stereotype that men don’t like to stop and ask for directions and women do, Baldwin added. [br] Which statement is true of the description in the first two paragraphs?
选项 A、If Coyne had stopped the car in time, he wouldn’t have hit the woman.
B、The woman would have been knocked over, if Coyne had followed the traffic regulations.
C、Coyne is not really driving so it is impossible for him to have hit the woman.
D、If the woman had not crossed the street suddenly, Coyne would not have hit her.
答案 C
解析 根据第一段和第二段的内容，读者可以知道，这不是Coyne真实的驾车经历。第二段的第一句是虚拟语气，意思是，即使他没有及时刹车，那位妇女也是安全的。因此A、B和D都不符合句意。
