题目：

In the year following an eight-cent increase in the federal tax on a pack of cigarettes, sales of cigarettes fell ten percent.  In contrast, in the year prior to the tax increase, sales had fallen one percent.  The volume of cigarette sales is therefore strongly related to the after-tax price of a pack of cigarettes.

选项:

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.

Although fullerenes--spherical molecules made entirely of carbon--were first found in the laboratory, they have since been found in nature, formed in fissures of the rare mineral shungite.  Since laboratory synthesis of fullerenes requires distinctive conditions of temperature and pressure, this discovery should give geologists a test case for evaluating hypotheses about the state of the Earth's crust at the time these naturally occurring fullerenes were formed.

From 1978 to 1988, beverage containers accounted for a steadily decreasing percentage of the total weight of household garbage in the United States.  The increasingly widespread practice of recycling aluminum and glass was responsible for most of this decline.  However, although aluminum recycling was more widely practiced in this period than glass recycling, it was found that the weight of glass bottles in household garbage declined by a greater percentage than the weight of aluminum cans.

请教Tina老师，我这题可以理解C，但不知道为什么A不对。前文说回收铝比回收玻璃更普遍，但是重量的减少铝却比玻璃少。A选项说相同大小（控制变量）的玻璃瓶比铝重，因此虽然铝比玻璃回收多，但由于其比玻璃轻，因此会产生两者在重量减少上的不一致（加强了文章结论的可能性）。希望老师解答，谢谢！

The federal immigration station on Ellis Island, which was first opened in 1892, then rebuilt in 1900, processing nearly three quarters of all immigrants entering the United States in the first quarter of the twentieth century.
请教Tina老师，我觉得这个题B选项的错误是主动词的错误，意思的重点是process而不是open和rebuilt；但是B选项中的open的主动用法与having processed是正确的吗（如果having processed是错误的，应该是怎么改？processing吗？）。此外，我还想问一下D选项的then rebuilt与前面的open为什么没有连词，这里的rebuilt与open是过去分词做形容词的结构吗？如果不是，为什么前面没有be动词？

Even though it was not illegal for the bank to share its customers' personal and financial information with an outside marketing company in return for a commission on sales, the state's attorney general accused the bank of engaging in deceptive business practices by failing to honor its promise to its customers to keep records private.
请教Tina老师，这道题我选的B，虽然我觉得A的语言更好，但我排A的理由是认为它的这个by更有可能修饰在主动词accuse，因此造成语义混乱，所以我选了一个指代性更好的B，虽然感觉它的形式不如A而且its太多了，但也没啥错。。请老师帮助纠正我的思路
