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.

A Swiss government panel recommended that the country sell about half its gold reserves and this raised fears of other countries that do the same and inundate the market.
请教下王文静老师，这道题我选了B，在这里我想弄明白非限定性定语从句的用法。在非限定性定语从句中，逗号后面的which一般可以指代逗号前的名词或代词，也能指代逗号前的那个句子，即指代逗号前说的那件事，那么在B中我觉得which指代的是这个政府卖掉黄金储备的这件事引起了其他国家的担忧，所以我选的B。而E的话，由于是现在分词作修饰语，感觉是说政府卖出去黄金储备这件事的时候提升了其他国家多担忧，这样的体现不出来后半句是前半句的结果，反而体现的是两者是同时的事情，觉得逻辑上会有问题。还请老师解答下，谢谢。

In a certain group of 50 people, how many are doctors who have a law degree?

  1. In the group, 36 people are doctors.
  2. In the group, 18 people have a law degree.

The diagram shows that in total of 50 people; ‘x’ are doctors without a law degree while ‘z’ are law degree holders and are not doctors. One needs to calculate how many are doctors who have law degree (y).

老师这个题我选c，我的理解一开始是36+18-50=4就是医生有学位的人数，但我又仔细想了下，医生的职业，而拥有学位是一个特质，两个性质分类不一样的不能直接拿来计算，有可能这18个有学位的都是医生，我下意识的把这50个人都默认为医生了，老师我的理解这样对吗？什么类型会像我那样计算

In little more than a decade, Argentina has become the world's leading exporter of honey, with nearly 90,000 tons a year sold to foreign markets, almost half of which going to the United States.
请王文静老师回答下，这道题我首先排除了B、C、D，因为我觉得后半句加了it的话，指代的是主句的逻辑主语Argentina，所以语义逻辑不对，排除BCD。A和E当中，有老师说with引导的句子和主句语义不是伴随关系，这个伴随关系需要怎么定义。我听了一些录音，说当with的句子内容是with所修饰的句子内容的一部分时，才可以用。那么回到这道题，如果选A，我认为“伴随着9万吨销量卖给海外市场，阿根廷成为了世界最大的蜂蜜出口国”，是没有问题的，因为蜂蜜销往海外的销量确实是成为出口国的一部分内容啊。而我觉得A中的问题在于sold的被动问题，即主句逻辑主语是Argentina，而with中的sold逻辑主语是honey，就导致主从句逻辑主语不一致，所以我排除了A。那么我的问题重点在于：1. with的用法到底是什么？我对with的分析是否正确，若正确，那么A选项改为“with the sale of nearly 90,000 tons a year to foreign markets, with almost half going”是否正确；2. 对A、E选项的后半句的逻辑成分是否正确？虽然按我的逻辑选了E，但是E的后半句的逻辑成分我不太清楚。谢谢。
