参考答案

正确答案：A
解析：这是一道细节题。根据原文第六段“Although retailers offer would-be purchasers basic safety instructions and recommend that riders wear gloves，helmets，goggles，boots and elbow pads，there is no license required to drive a quad bike and few ways to encourage people to ride them wisely．Employers are required to provide training to workers who use squad bikes，”(尽管售货商会给准客户基本的安全指导，也会建议车手带好手套，头盔，护目镜，靴子以及护肘，但驾驶四轮摩托并不需要驾照，也没有什么可行方法能够促使人们理性驾驶。如果员工用越野车上班的话，老板要给他们提供培训，)可以看出，如果员工上班用越野车的话，老板要让他们上课，故选A。
