请教OG-88,og-89

In many corporations, employees are being replaced by automated equipment in order to save money. However, many workers who lose their jobs to automation will need government assistance to survive, and the same corporations that are laying people off will eventually pay for that assistance through increased taxes unemployment insurance payments.

88. The author is arguing

B) replacing people through automation to reduce production costs will result in increases of other costs to corporations.

89.Which of the following, if true, most strengthens the author's argument?

a)Many workers who have already lost their jobs to automation have been unable to find new jobs.

b)Many corporations that have failed to automate have seen their profits decline.

c)Taxes and unemployment insurance are paid also by corporations that are not automating.

d)Most of the new jobs created by automation pay less than the jobs eliminated by automation did.

e)The initial investment in machinery for automation is often greater than the short-term savings in labor costs.

88题问的是作者争论的焦点，答案是b, 厂房没有争得实际的经济效益

89题问支持，那也应该是支持争论的焦点：经济效益才是呀，怎么又跑到担心工人找不到活干呢？答案a,. 这道题目到底什么是main point? 我总觉得是经济效益。请赐教，谢谢。

作者的观点是：机器取代人－更多人失业－政府要帮助失业者－帮助的资金来自于增加的税金和失业保险，所以企业通过自动化得到成本好处，但会增加别的支出。

把a取非：如果因为使用automated equipment而失业的工人都能再找到工作，政府也就不用提供assistance了，也就不用增加tax和insurance了，作者就得不出结论“replacing people through automation to reduce production costs will result in increases of other costs to corporations.”

a取非削弱，所以a是加强

nobody knows???

Please help~Thanks

added 有further的意思，这里added support 就是进一步支持，没有strenghten

还是og的解释：（og的解释搞的我真晕）

By saying that costs associated with unemployment C weakens the argument.

看不出来哪里是weaken的，请指教。

c)Taxes and unemployment insurance are paid also by corporations that are not automating.

觉得是irrelevant的。因为题目中并没有提到corporations that are not automating的呀！！

看得头晕，请大家指教。。。
