C的意思不理解啊....每2000里500被剔除的话,这2000要都是好的,这500不就浪费掉的...这2000都烂,剩下的1500不也很烂?
第一题，A是说，气袋不经意就会被激发开，然而造成更多的死亡率，
这就是在说，气袋的不好，攻击了题目，说交通部门要就要安装的建议！
第二题，注意题目是说Critics of sales seminars 从87后才说怪seminar 不好，
那这句话的意思就是说，他们认为87前情况于此相反，》seminar没什么不好，
选项A说87以前似乎不参加seminar的人 ，sales也是最高的，跟87后citics的观点一样，这样就削弱了。
第三题，选E！i'm quite sure to choose e!
看清楚题目真正问的，MM，！
他问你，你认为反对那个管理者计划的理由是说他提前假设了。。。。？
他提前假设了，accepted 1500个是一样合格的，但是他蛮逻辑没学好啊，不一定每一次生产过程defect rate都是一样的啊，如果只有1499个符合标准，或者如果有1501个符合标准的话，他不是滥竽充数就是浪费了！
