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 and unemployment insurance payments.increased taxes and unemployment insurance payments.

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.

The threat envisioned by the author to the economic survival of workers displaced by automation will be serious only if they cannot find new jobs. Choice A, the best answer, says that there are already many such workers unable to find new jobs, and so strengthens the author’s argument.

Since the causes for declining profits for corporations that fail to automate are not analyzed in the passage, B is inappropriate. By saying that costs associated with unemployment C weakens the argument. Since the author tacitly grants that, initially, automation will cut costs, the detail given in D provides us added support. Choice E is inappropriate because it concerns short-term rather than long-term results of automation.

我不是很明白D所说的 added support（有人说是further support，但我也不知道further support是什么），到底什么是added support呢？ D是support什么的呢？ 又为什么不是加强原文结论的呢？ 请大家多多指导
