C 平行错误，devise和employ 导致 HC 可以去。。 有因果关系 不是单纯的并列
选对了 但差点选了C 平行问题 还有那个was 有问题
A选项：主语是Henry Cavendish's apparatus, 有问题，应该是Henry Cavendish这个人才能执行devising... and employ...的任务；
B选项：同理
C选项：三个句子都用and连接，显得笨重，前面两个并列的动作devised和employed可以用and 连接，但是后一个是一个新起的句子，直接就：In 1797-1798开头更好；
D选项：使用employ这个动词，好过用employment of commonly...这个名词；
CE的区别：句子成分有区别，表达的核心内容不同
修正： A和E的差别，错误不在enable 或者able，sth enable sb to do 或者sb is able to do 都是正确的表达；AE的真正差异在于主语不同，by devising 这句主语应该是人，而不是装置，所以A排除
C. Connecting the three parts of the sentence with two occurrences of and is
awkward; the first two parts are best connected by and, but the final portion
expressing what Cavendish achieved would be better expressed, for example, as a
new sentence beginning, In 1797–1798, he employed.
B-时间区间有歧义
C-and平行结构有问题
D-平行结构问题
A和E里面，具有enable能力的是人，不能是装置，排除A，剩E
