我觉得还是应该选C Industrial accidents are more common when some of the people in safety-sensitive jobs have drinking problems than when none do. (背景) Since, even after treatment, people who have had drinking problems are somewhat more likely than other people to have drinking problems in the future, any employer trying to reduce the risk(目标) of accidents should bar anyone who has ever been treated for a drinking problem from holding a safety-sensitive job(方案).
B选项 Many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs. many accidents 到底占总数的多少比例不知道,因为many在nonsafety-sensitives jobs 不能说明few accidents在safety-sensitive jobs 中 C选项则直接削弱结论,隔断目标和方案的联系,削弱 |
