82. In contrast to large steel plants that take iron ore through all the steps needed to produce several different kinds of steel, processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology and remain economically viable.
(A) processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology and remain
(B) processing steel scrap into a specialized group of products has enabled small mills to put capital into new technology, remaining
(C) the processing of steel scrap into a specialized group of products has enabled small mills to put capital into new technology, remaining
(D) small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and remain
(E) small mills, by processing steel scrap into a specialized group of products, have been able to put capital into new technology and remained
The logical comparison here is between large steel plants and small mills. Choices A, B, and C illogically contrast large steel plants with [the] processing [of] steel scrap. Further, in choices B and C remaining is not parallel with put; consequently, it is not clear exactly what is remaining economically viable. The contrast between large plants and small mills is logically phrased in choices D and E, but remained in E is not parallel with put. Choice D, the best answer, uses parallel verb forms to complete the construction have been able to put... and remain.

解释中SAID：consequently, it is not clear exactly what is remaining economically viable。
remaining。。。结尾不是可以表达一种结果么？为什么not clear exactly what is remaining economically viable

想旅游的笨蛋

. Further, in choices B and C remaining is not parallel with put; consequently, it is not clear exactly what is remaining economically viable.

表结果的分词结构，是前面那整句话产生的结果

而这里D、E显然从逻辑上、句子原意上都不能表结果

OG并不是说D、E选项表remaining引导结果状语，而是一种伴随状语，而remaining的逻辑主语 不清
