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.

While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.
老师好， 首先读题的意思是说花费在维持nuclear的钱其他power的钱差不多，但是 fixed costs方面，nuclear更贵。 然后全句都是划线部分，看到句子的每个部分都像是差异点。因为每次做全画线句子都错，希望老师详细说明下全画线找考点差异点的技巧。另本次错选E 谢谢。

In 1850, Lucretia Mott published her Discourse on Women, arguing in a treatise for women to have equal political and legal rights and for changes in the married women's property laws.
老师好， 从and for changes...可以确定划线部分使用for ... rights for women，所以答案锁定B、E。 我选择B，理解意思是L.M发表这个读物，以此来争取女性权利等等。 E做题时也理解，意思可以是D on W 这个读物是一个争取女性权利什么的treatise。 想请教这块我该如何判断，到底谁是发起者比较合理？（解释说明谁是合理的？） 谢谢

Politician: Hybrid cars use significantly less fuel per kilometer than nonhybrids. And fuel produces air pollution, which contributes to a number of environmental problems. Motorists can save money by driving cars that are more fuel efficient, and they will be encouraged to drive hybrid cars if we make them aware of that fact. Therefore, we can help reduce the total amount of pollution emitted by cars in this country by highlighting this advantage of hybrid cars.

Which of the following, if true, would most indicate a vulnerability of the politician’s argument?
老师好， 读出原文意思是：Hybrid cars 节约燃料。燃料造成环境污染。Motorists 用高效燃料可以省钱，因此Motorists被鼓励用hybrid cars。因此用hybrid cars可以减少cars排放的污染。 没有抓到原文的逻辑关系，Hybrid cars和高效燃料和鼓励用Hybrid cars是什么样的逻辑关系？谢谢

Which of the following most logically completes the passage?

Pecan growers get a high price for their crop when pecans are comparatively scarce, but the price drops sharply when pecans are abundant. Thus, in high-yield years, growers often hold back part of their crop in refrigerated warehouses for one or two years, hoping for higher prices in the future. This year's pecan crop was the smallest in five years. It is nonetheless quite possible that a portion of this year's crop will be held back, since ______________.
老师好， 读题目意思是：产量多价格低，产量低价格高，所以高产年份就收起来一两年，等未来高价格再卖。今年是五年来产量最少的一年，尽管如此，他们还是收起来了。要找到一个合理的解释。 这道题目并没有想到有什么合理的解释呢。感觉产量少了价格就高起来了，应该卖了啊，有什么理由不卖呢？ 谢谢

which of the following ,if true, most seriously weakens the argument?
原文读的不太懂，大概理解是生产modelXT要解雇工人之类的，看选项觉得答案应该讲到modelXT和Z的区别，但是选不出来，麻烦老师讲解一下～～

The spacing of the four holes on a fragment of a bone flute excavated at a Neanderthal campsite is just what is required to play the third through sixth notes of the diatonic scale—the seven-note musical scale used in much of Western music since the Renaissance. Musicologists therefore hypothesize that the diatonic musical scale was developed and used thousands of years before it was adopted by Western musicians.

Which of the following, if true, most strongly supports the hypothesis?
