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 Patton City, days are categorized as having heavy rainfall (more than two inches), moderate rainfall (more than one inch, but no more than two inches), light rainfall (at least a trace, but no more than one inch), or no rainfall.  In 1990, there were fewer days with light rainfall than in 1910 and fewer with moderate rainfall, yet total rainfall for the year was 20 percent higher in 1990 than in 1910.
 
If the statements above are true, then it is also possible that in Patton City
读A的时候，觉得在1990年heavy rain的天数应该比1910时的多，又因为原文说在1990年light rain和moderate rain的天数比1910年的少，但是1990年的total rainfall却比1910年的多，所以觉得A选项说反了，直接杀掉了。然后，觉得D中total rainfall和moderate rainfall原文都说过，虽然也觉得不是很对，还是选了D。逻辑题正确率一直不高啊，快考试了，焦虑啊！求老师解答！

vehicles, almost all of which are gasoline powered, and will not be sub-

In a study conducted in Pennsylvania, servers in various restaurants wrote "Thank you" on randomly selected bills before presenting the bills to their customers.  Tips on these bills were an average of three percentage points higher than tips on bills without the message.  Therefore, if servers in Pennsylvania regularly wrote "Thank you" on restaurant bills, their average income from tips would be significantly higher than it otherwise would have been.
 
Which of the following is an assumption on which the argument relies?
看完选项就直接错选A，原因是觉得A说tip给的多了是因为不仅影响了长期客户也影响了偶尔来的，觉得正好和原味最后说的预期增长有关系。知道答案是B后分析觉得B说的是写不写thank you与消费者改变不改变习惯的事，与原文无关阿。 请老师讲解 谢谢。

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.
 
Which of the following, if true, most strengthens the argument?
留下BC是因为觉得和文章有关，比较BC后还很难判断但此时倾向于C，又读了遍原文觉得文章说失业率没有降低，政府又开设了免费的项目，然后师生比例也没有变化，所以自己就想免费的项目能吸引学生，学生人数上涨，师生比要不变化那老师也增多 故最后错选C。 请老师讲解 谢谢。

Construction of the Roman Colosseum, which was officially known as the Flavian Amphitheater, began in A.D. 69, during the reign of Vespasian, was completed a decade later, during the reign of Titus, who opened the Colosseum with a one-hundred-day cycle of religious pageants, gladiatorial games, and spectacles.
BC比较：排除正确答案C的原因是officially known的都是construction of the Roman Colosseum，没必要多个which 来指代一下。 请老师指出我的错误，谢谢。
