63.   

Companies O and P each have the same number of employees who work the same number of hours per week.  According to records maintained by each company, the employees of Company O had fewer job-related accidents last year than did the employees of Company P.  Therefore, employees of Company O are less likely to have job-related accidents than are employees of Company P.

Which of the following, if true, would most weaken the conclusion?

(B) Company P considered more types of accidents to be job-related than did Company O.【种类多并不一定容易出事故啊,为啥选这个】
(E) The majority of job-related accidents at Company O involved a single machine.【E咋不对捏】

题目问的是weaken,这是一种方式啊,没说一定,但是可能~~~
题目讲的是number of employees,E谈到mechine去了~~无关吧~~

employees of Company O are less likely to have job-related accidents than are employees of Company P
weaken就是找个理由说上面这句话O比P事故少不成立啊,也就是说O的事故不一定比P少
B选项很对啊,因为P把很多情况都当成Accident了啊,所以O比P事故多神马的

谢谢LS的两位大侠~~~懂了~~~~~~~~~~~~

还有一个题请教大家~

Paint on a new airliner is usually applied in two stages:  first, a coat of primer, and then a top coat.  A new process requires no primer, but instead uses two layers of the same newly developed coating, with each layer of the new coating having the same thickness and weight as a traditional top coat.  Using the new process instead of the old process increases the price of a new aircraft considerably.

Which of the following, if true, most strongly indicates that it is in an airline's long-term economic interest to purchase new airliners painted using the new process rather than the old process?

(B) A layer of primer on an airliner weighs more than a layer of the new coating would by an amount large enough to make a difference to that airliner's load-bearing capacity.
【之说了difference,怎么说就primer不好呢?这句话都没咋看懂的说】

就是要说primer不好,所以长远看来就该换用新的这种方法~~虽然新的方法可能increase price
