Due to automobile-related jobs in the 1920's employing one of every eight workers, the automobile industry dominated the American economy.

(A) Due to automobile-related jobs in the 1920's employing one of every eight workers, the automobile industry dominated the American economy.
(B) One out of every eight workers were employed in automobile-related jobs in the 1920's, with the American economy being dominated by the automobile industry.
(C) The automobile industry dominated the American economy in the 1920's, with one of every eight workers having been employed in automobile-related jobs.
(D) In the 1920's, the automobile industry had dominated the American economy, when one out of every eight workers was employed in an automobile-related job.
(E) In the 1920's, the automobile industry dominated the American economy, with one out of every eight workers employed in an automobile-related job.

我想问下 one of every eight workers，One out of every eight workers有什么区别么，解释为前者是“八人中的一人”，而后者是“每八人中就有一人”；我觉得这没有区别啊？另外，解释中说了in the 1920’s“在…年代”表达过去的时间，用过去完成时态。但答案选的是E，过去时，这怎么解释？

one of every eight workers  和 one out of every eight workers之间当然有区别。前者指的是“每8个里面有一个”，重点在一个什么东西；而后者是一个表示频率或者说概率的结构。

1、消灭零回复！
2、用过去完成时需要有明确的过去时间点，而此句中没有。
