问题 单项选择题

专家通过对工作场所安全的研究发现:当建筑工人的工作负荷增加时,工人的受伤率会增加。由于在工作负荷增加时,没有经验的工人常常被雇用,受伤率的增加无疑是由于没有经验工人的高事故率所致。
以下哪一项如果正确,最能削弱题干结论______

A.建筑企业的工作负荷增加时雇用的没有经验的工人只是负责临时的工作
B.工作场所安全研究仅集中在那些因工伤而无法工作的工人
C.生产性企业的受伤率比建筑类企业低
D.雇用没有经验的工人做有潜在危险的工作时,公司被要求为其提供培训

答案

参考答案:D

解析: 题干的结论是:无经验的工人被雇用,造成事故率增加。A项雇用的工人只负责临时工作,临时工作也可能有危险性,所以不能削弱结论。B项没有指出工伤的人员和没有经验之间的关系,故B项也不能削弱。C项为无关选项。D项工人培训后有了经验,但是事故率依然增加,削弱了结论。故本题选D。
