[讨论]大家帮忙看看这道LSAT逻辑题（不知道编号姑且叫缝衣针问题吧）

        If the needle on an industrial sewing machine becomes badly worn, the article being sewn can be ruined. In traditional apparel factories, the people who operate the sewing machines monitor the needles and replace those that begin to wear out. Industrial sewing operations are becoming increasingly automated, however, and it would be inefficient for a factory to hire people for the sole purpose of monitoring needles. Therefore a sophisticated new acoustic device that detects wear in sewing machine needles is expected to become standard equipment in the automated apparel factories of the future.

Which one of the following is most strongly supported by the information above?

(A) In automated apparel factories, items will be ruined by faulty needles less frequently than happens in traditional apparel factories.

(B) In the automated apparel factories of the future, each employee will perform only one type of task.

(C) Traditional apparel factories do not use any automated equipment.

(D) The needles of industrial sewing machines wear out at unpredictable rates.（D）

               (E) As sewing machine needles become worn, the noise they make becomes increasingly loud

答案是D， 我怎么觉得E更像答案？

A B C 明显错误

感觉上这道题是想向读者传达一个意思 就是这种不确定性导致不采用人工就要建立这种a sophisticated new acoustic device 而不是具体通过声音还是什么方式

D 是从这段文字总体宏观上的把握

而E 可能lz你被acoustic这个词局限住了

有些道理，让我再想想。谢谢melodyflying。
