they are for 比较结构不对称(they指的是standards,但是前面结构没有are) 逗号会引起歧义,导致almost all of which are gasoline powered,变成插入语部分,而will be not subjected的主语变成law
时态错误,而且they are指代错误
they指代不清
逗号使得all of which引导的变为插入语部分,后面的will not be subjected to 引导的从句主语变成了it
代词指代不对,比较的是标准,是不同事物的标准,所以应该用those
will not be容易产生歧义:主语变成the law; they指代不清
will重复
A. A的逗号会引起歧义,导致almost all of which are gasoline powered,变成插入语部分,而will be not subjected的主语变成law
and不平行,会造成主语是law的歧义;并且they指代错误,这里they指代的是前面的standards
they are应该指代standards,但是前面主句的主语是it, 逗号引起歧义导致almost all of which...变成插入语,而subjected to的主语是the law
will not 应该是和are gasoline powered是平行的,并且这里面they are是错误的,they指的是同一群体
and will有歧义,逻辑主语可能是it。 they指代不清。
