A选项里having作定语修饰pollutants, redundant and not clear,而且they的指代有不清,
B选项用while doing的结构承接了前主句表结果,且用了that定语从句修饰pollutants,没什么明显问题。
C选项,While表达的是于此同时的意思,但是却变成了they have introduced并列,感觉并非原意而且while + doing一般表示同时性,而且pollutant与which之前插入了at the same time, 导致修饰不清。
DE都用了but,强调了转折而非同时性,D中的pollutants at the same time that have也是有修饰问题,E也是pollutant, having blabla 这种非限定修饰GMAT不会写入正确里的

个人意见哈,

谢谢啊!! 但是有一块不太懂
A最后的pollutant, having...为什么会显得redundant and not clear?我觉得修饰的挺清晰的啊..

A 选项的having 修饰的是Industrialization and modern methods  。
所以错误。 要修饰pollutant才对
