In 1852 Robert Angus Smith published a detailed report of the chemistry of rain in a large area around the city of Manchester, England, noting that coming closer to town, the city air became increasingly acidic.
coming 主语不对
coming的动作发出者是the chemistry of rain
coming主语错误了,不能选这个。increasingly和more重复;只能选B了,increasingly和和more一样的效果。。。好吧。。。
coming的主语对不上
每句都要有主谓,所以前半句错(加个by with while 正确)
