问题     Every day 25 million US children ride school buses. The safety record for these buses is much better than for passenger cars; but nevertheless, about 10 children are killed each year riding on large school buses, and nearly four times that number are killed outside buses in the loading zones. By and large, however, the nation’s school children are transported to and from school safely.
    Even though the number of school bus casualties(伤亡事故)is not large, the safety of children is always of intense public concern. While everyone wants to see children transported safely, people are divided about what needs to be done — particularly whether seat belts should be mandatory(强制性的).
    Proponents of seat belts on school buses — many of them are parents and medical organisations — argue that seat belts are necessary not only to reduce fatality and injury, but also to teach children lessons about the importance of using them routinely in any moving vehicle. A side benefit, proponents point out, is that seat belts help keep children in their seats, away from the bus driver.
    Opponents of seat belt installation suggest that children are already well protected by the school buses that adhere to the National Highway Traffic Safety Administration’s(NHTSA)safety requirements set in 1977. They also believe that many children won’t wear seat belts anyway, and that they may damage the belts or use them as weapons to hurt other children.
    A new Research Council report on school bus safety suggests that there are alternate safety devices and procedures that may be more effective and less expensive. For example, the study committee suggested that raising seat backs four inches may have the same safety effectiveness as seat belts.
    The report sponsored by the Department of Transportation at the request of Congress, reviews seat belts extensively while taking a broader look at safety in and around school buses.
It may be inferred from the passage that______.
选项 A、many of the opponents of seat belt installation are parents and federal officials
B、proposals of seat belts on school buses would be seriously considered
C、the idea of raising seat backs four inches will be taken into consideration
D、the government will carry out the idea of installing seat belts on all school buses
答案B
解析 最后一段讲到：在国会的要求下，交通部提供的这份报告要求广泛地考察座位安全带问题，同时要广泛调查校车内部以及周围的环境安全。extensively说明了关注的程度，因此选择B)。由第3段可知家长和医疗机构是使用安全带的支持者，所以A)不对；第5段只指出有一种替代方法，但并未指出它会被考虑执行，所以C)不对；D)文中未提到。
