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.

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.

Even though sub-Saharan Africa often evokes images of drought and famine, researchers say that the area is the home of more than 2,000 grains, vegetables, roots, fruits, and other foods that have the possibility for feeding the continent, even other parts of the world.
other parts of world 和the continent对应。所以even后面不用加介词。排除BCE。在AD中比，一处是have the possiblity 和could的区别。另一处是even前加不加and。这两处我都不会比，做不出来了。

Rock samples taken from the remains of an asteroid about twice
the size of the 6-nuke-wide asteroid that eradicated the dinosaurs
has been dated to be 3.47 billion years old and thus is evidence
of the earliest known asteroid impact on Earth.
在复习中我感觉较有难度的是对SC语意精准地理解及辨别选项的细微差别造成的语意区别。常见的问题有以下两大类： 1． 两个选项的差别只有某个介词时，我会觉得难以定度。就算我理解原句作者想表达的意思，但是对于选用哪个介词能更精确地表达句意还是不太拿捏得准。 以下是该情况的例子之一 (ID: 1736)（括号代表画线处） Rock samples taken from the remains of an asteroid about twice the size of the 6-mile-wide asteroid that eradicated the dinosaurs （has been dated at 3.47 billion years old and thus is） evidence of the earliest known asteroid impact on Earth. A. has been dated at 3.47 billion years old and thus is B. has been dated at 3.47 billion years old and thus C. have been dated to be 3.47 billion years old and thus are D. have been dated as being 3.47 billion years old and thus E. have been dated at 3.47 billion years old and thus are 我做此题时觉得CE差别不大，对于这种语意精确度的敏感性该如何训练？ (另：感觉这种考题在GMAT 考试中有增多趋势，故不能随便蒙一个答案) 2． 两个事物作比较用than 连接时，较容易头晕。因为此时对画线的第二个比较对象给出的选项中有省代词的，有省动词的，还有都省的……; 然后我就会觉得比到最后好像剩下的两个都还可以。 以下是该情况的例子之一 (ID: 1363) Accordingly to public health official, in 1998 Massachusetts became the first state in which more babies were born to women over the age of thirty （than） under it. A. than B. than born C. than they were D. than there had been E. than had been born 我觉得AC 都还凑合，而A 省得太多了。 请问针对以上情况该如何进行训练？ 谢谢！
