A、During the year following the tax increase, the pretax price of a pack of cigarettes did not increase by as much as it had during the year prior to the tax increase.
B、The one percent fall in cigarette sales in the year prior to tax increase was due to a smaller tax increase.

D、For the year following the tax increase, the pretax price of a pack of cigarettes was not eight or more cents lower than it had been the previous year.

Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually unregulated since they were developed more than 50 years ago.
首先杀DE 剩下A、B、C B 我觉得introducing和while前面的半句句子不平行,而且当时做题时理解成unregulated的是industrialization and modern methods,所以就没选。 A和C的差别是at the same time放的位置,还有having和which have,觉得having更简洁明确的指明发起者是methods,所以就选择了A。
