[求助]GWD30-1& 30-19，不解中。。。

GWD30-Q1:

The artist Renoir’s last word was “flowers,” spoken as they arranged a bouquet of roses just picked from his garden in a vase on his bedroom windowsill.

1. as they arranged a bouquet of roses just picked from his garden
2. as a bouquet of roses had been just picked from his garden and was being arranged
3. as a bouquet of roses just picked from his garden was being arranged
4. during the arrangement of a bouquet of roses just picked from his garden
5. while they arranged a bouquet of roses that had just been picked from his garden

给出的答案是C，但是being在句中不是GMAT语法大忌么？偶选的D，觉得选项中就D比较合适了。是不是答案给错了呢？

Which of the following, if true, most seriously undermines the argument above?

1. Some companies place employees who are being treated for drinking problems in residential programs and allow them several weeks of paid sick leave.
2. Many accidents in the workplace are the result of errors by employees who do not hold safety-sensitive jobs.
3. Workers who would permanently lose their jobs if they sought treatment for a drinking problem try instead to conceal their problem and continue working for as long as possible.
4. People who hold safety-sensitive jobs are subject to stresses that can exacerbate any personal problems they may have, including drinking problems.
5. Some industrial accidents are caused by equipment failure rather than by employee error.

答案是C，偶选的D。

D说从事safety-sensitive 工作的人会产生压力，而这些压力会加重他们的问题，包括酗酒。这样就说明不是酗酒的人不适合从事safety-sensitive 工作，而是这种工作本身会导致很多问题，那么雇主只是简单紧致有酗酒史的员工从事safety-sensitive 工作的做法是不合适的，应该从别处下手根本解决。

C说酗酒员工害怕自己永远失业而隐藏自己酗酒问题。这个不是最好的削弱，因为C还说continue working for as long as possible.说明酗酒员工终会被雇主发现而被禁止工作，说明雇主的做法还是有效只是产生效果的时间会延长。

这两道题很郁闷！还请NNs不惜指点啊！！！

前者

这里being不是redundancy，而是被动语态进行时，不在大忌之例

且这里从句中主要强调rose，所以“they”、“arrangement”作主语都不好

后者

d选项中，压力导致酗酒，可是招聘没有酗酒习惯的人即使在压力之下，也会相对少酗酒吧

c选项中，隐藏酗酒问题，就导致不接受酗酒治疗。而如果没有禁令，可能虽然酗酒，但还是去治疗。因此公开禁止酗酒者从事此高危职业，有可能增加风险。
