A factory was trying out a new process for producing one of its products, with the goal of reducing production costs. A trial production run using the new process showed a 15 percent reduction in costs compared with past performance using the standard process. The production managers therefore concluded that the new process did produce a cost savings.

Which of the following, if true, casts most doubt on the production manager’s conclusion?

(A) In the cost reduction project that eventually led to the trial of the new process, production managers had initially been seeking cost reductions of 50 percent.

(B) Analysis of the trial of the new process showed that the cost reduction during the trial was entirely attributable to a reduction in the umber of finished products rejected by quality control.

(C) While the trial was being conducted, production costs at the factory for a similar product, produced without benefit of the new process, also showed a 15 percent reduction.

(D) Although some of the factory’s managers have been arguing that the product is outdated and ought to be redesigned, the use of the new production process does not involve any changes in the finished product.

(E) Since the new process differs from the standard process only in the way in which the stage of production are organized and ordered, the cost of the materials used in the product is the same in both processes.

请帮忙翻译一下B项。

Analysis of the trial of the new process showed that the cost reduction during the trial was entirely attributable to a reduction in the umber of finished products rejected by quality control.

umber我觉得是错了,应该是number才对,类似的错误og出现了不少.

新技术产品实验分析显示:使用新技术所引起的成本降低完全是由于那些被质量控制所拒绝的产成本数量的降低所导致的.

偶也没看懂……

C) While the trial was being conducted, production costs at the factory for a similar product, produced without benefit of the new process, also showed a 15 percent reduction

红色部分到底是什么意思呢？是作为分词修饰product吧？可是为什么会有“，”我记得在语法里过去分词短语前面不可以有，吧？如果是谓语，also前面该有个and…………

啊，谁能看懂？谢谢…………鞠躬下……

测试进行时，在工厂不利用新的生产流程来生产类似产品，成本也有百分之十五的降低。

大致这个意思。

红色部分是修饰它前面的名词"a similar product"的。有逗号是可以的。语法题里有很多例子。

接着请教一个问题:

(B) Analysis of the trial of the new process showed that the cost reduction during the trial was

entirely attributable to a reduction in the number of finished products rejected by quality

control. 新生产线有效是因为减少了废品的个数. 具体解释了结论中为什么省钱的原因,证明不是偶然的saving, 是支持,

请问大家一般来说, 解释会是一种支持嘛 ??????? 谢谢

Choice B is incorrect since finding the source of the cost savings in the trial shows

that the savings were no mere accident and so reinforces the managers’ conclusion. 支持
