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.
 
The argument above requires which of following assumptions?

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.
C、The pretax price of a pack of cigarettes gradually decreased throughout the year before and the year after the 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.
E、As the after-tax price of a pack of cigarettes rises, the pretax price also rises.

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.

Deliberately imitating the technique of Louis Armstrong, jazz singer Billie Holiday'sapproach to singing was to use her voice like an instrument, in that she ranged freely over the beat, flattened out the melodic contours of tunes, and, in effect,recomposed songs to suit her range, style, and artistic sensibilities.
这题当时选了E。思路是这样的，A B发起者有毛病，排除。in that 和in the same way that 感觉在绕，当然可能忽略了意思呀，就排除了D，然后觉得C 的like 后面接句子没E like 后面接名词好，就选了E。 做完后review这题，因为时间充足，就注意了意思，发现D是说的最完整的，使用use的方式相同，减少了歧义。 然后听录音，老师们（貌似博森历史上的三个老师在这题上都有录音），都把关注点放在了动词上，特别是recomposed 的对应上。这点上我觉得，C D E划线前面怎么着都有个approach或者used,而且D作为正确答案recomposed发起者也是she 归根结底上还是B H那人发出的动作。所以我个人观点觉得C D E 在动词上没有问题。这题动词里flatten不认识，其他词认识，但是堆在一起，这句话的动词相互关系完全搞不清。 这题我倾向于不借助动词而用like那处做出判断，但对于like后面能否接句子我自己心里也没数。 总之这题很纠结

Trans World Entertainment Corporation, which owns the Record Town and Saturday Matinee retail chains, announced that since sales of up to one-fourth of its stores are poor, they will be closed.
announced 造成后面的句子只能用过去时态，A B杀掉。C 比A 有两点相对差些，一点是没that,不过这点不致命，主要是was closing ,close 在我的眼中应该不一个能够持续的动作。在都不完美的A C中，还是回头选了A。

Some species of Arctic birds are threatened by recent sharp increases in the population of snow geese, which breed in the Arctic and are displacing birds of less vigorous species.  Although snow geese are a popular quarry for hunters in the southern regions where they winter, the hunting season ends if and when hunting has reduced the population by five percent, according to official estimates.  Clearly, dropping this restriction would allow the other species to recover.

As a large corporation in a small country, Hachnut wants its managers to have international experience, so each year it sponsors management education abroad for its management trainees.  Hachnut has found, however, that the attrition rate of graduates from this program is very high, with many of them leaving Hachnut to join competing firms soon after completing the program.  Hachnut does use performance during the program as a criterion in deciding among candidates for management positions, but both this function and the goal of providing international experience could be achieved in other ways.  Therefore, if the attrition problem cannot be successfully addressed, Hachnut should discontinue the sponsorship program.
