问题 According to the passage, if a driver falls asleep in one of the test cars, ______.
The author may agree that the Selby crash ______.

选项 A、triggered the development of the awake system
B、happened because the train driver drifted off at the wheel
C、highlighted the advantages of installing the awake system
D、caused researchers’ concern about the practicality of the awake system

答案C

解析 本文介绍了唤醒系统的研发,结合第4段末句可以知道,作者提到Selby撞车事故是为了表明唤醒系统可以避免这种事故的发生,即它的好处,由此可见,选项C为本题答案。原文并没有显示Selby撞车事故和研发唤醒系统的先后顺序,也没有提及它们之间的因果关系,因此选项 A不正确;第4段第2句表明Selby撞车事故是因为小车司机睡着而引起的,选项B中的火车司机与事实不符;在第4段末句中,机动车协会提到了两点,一点是Selby撞车事故可以使用唤醒系统预防,另一点是对研发唤醒系统的实用性持谨慎态度,但这两点之间没有直接关系,因此选项D也不正确。
