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.

In parts of the Caribbean, the manatee, an endangered marine mammal, has long been hunted for its meat.  Having noted the manatee hunters' expert knowledge of manatees' habits, local conservationists are encouraging the hunters to stop hunting and instead to take tourists on boat rides to see manatees.  Tourist interest is high, so the plan has promise of achieving the twin goals of giving the former hunters a good income and helping ensure the manatees' survival.
 
Which of the following, if true, raises the most serious doubt about the plan's chance of success?
老师请讲解一下，为什么A不能削弱原文？如果说游客都不感兴趣而且也不愿意付钱的话，不就不能达到文中所期望的目标了么？ 而且E为什么可以削弱？就算用了大船不也能保持现在的收入么？

ID:174 1、原文：没太看看懂高亮的原文“effect on the bottom line”是什么意思？请老师帮忙仔细翻译一下 2、题干：没太看懂问题题干的表达“the evidence for price promotions 'effect on the bottom line 'is provided by " 又是指什么意思？ 3、选项： 我对原文大概的理解是“即使Price Promotion有不好的Effect，但公司管理层还是不愿意放弃这个策略”，那么问题问的这个不好的Effect是指什么？ 回看原文有提到过的不好的Effect有3个方面（1）Lack of lingering after effect ; （2）Inability to attract new customers (or does not increase the no. of long term customers ); （3）Run at a loss (more price promotion,more loss) 对应于选项，A和C都是提到过的不好的Effect，但是为什么正确选项是C？如何理解C选项？ 请老师帮忙解惑，感谢

Editorial:
 
In Ledland, unemployed adults receive government assistance.  To reduce unemployment, the government proposes to supplement the income of those who accept jobs that pay less than government assistance, thus enabling employers to hire workers cheaply.  However, the supplement will not raise any worker's income above what government assistance would provide if he or she were not gainfully employed.  Therefore, unemployed people will have no financial incentive to accept jobs that would entitle them to the supplement.
 
Which of the following, if true about Ledland, most seriously weakens the argument of the editorial?
…为了降低失业率，政府的一个措施，就是如果你找了工作，但是薪水低于政府assistance，则我给你supplement income:，另外如果有工作的人的薪水，这道题题目没看懂；怎么去理解有what的句子，老师之前也讲过a is to b what c is to d;这里what 表示就好像；这里的what怎么去理解，有没有类似像定语从句一样有规律的去解读what句型？

Two centuries ago, Tufe Peninsula became separated form the mainland, isolating on the newly formed Tufe Island a population of Turfil sunflowers.  This population's descendants grow to be, on average, 40 centimeters shorter than Turfil sunflowers found on the mainland.  Tufe Island is significantly drier than Tufe Peninsula was.  So the current average height of Tufe's Turfil sunflowers is undoubtedly at least partially attributable to changes in Tufe's environmental conditions.
 
Which of the following is an assumption on which the argument depends?
我解题思路-新的环境改变了植物高度；目前脑子里有的方法-1）看完题干自己可以拟出一个非常好的assumption（常识内的）-看完题干我想不出来，待定；2）排除他因-如果选项排除了XXX导致了高度变化（XXX是除了新环境因素以外所有其他因素）；也可以算assumption，C选项不错；3）另外就是取非，选项特别绕的时候我会选择取非；4）角度问题-选项的角度必须和结论的角度一样，即都是从政府/科学家等，这道题用不上；看了选项排除ABE；C我看了就是排除他因，参照物的环境没有变，则岛屿上的植物高度变化完全由岛屿环境决定，D选项我看到了height，soil，（我觉得脑补soil属于环境因素很正常吧？）俩个关键因素都在了，也就是说了环境中缺乏了植物长高的因素，这个是一个不错的assumption; 我并没有抬杠的意思；老师说的是soil就是无关；我分析了一下CD感觉的确environment-保持原汁原味的词汇的选项更安全；但是D说出了一个植物没有长高的原因-一个explanation；是不是strengthen？老师可否clarify一下assumption和strengthen的做题思路区别…

Archaeologists use technology to analyze ancient sites. It is likely that this technology will advance considerably in the near future, allowing archaeologists to gather more information than is currently possible. If they study certain sites now, they risk contaminating or compromising them for future studies. Therefore, in order to maximize the potential for gathering knowledge in the long run, a team of archaeologists plans to delay the examination of a newly excavated site.

Which of the following would be most useful to investigate for the purpose of evaluating the plan’s prospects for achieving its goal?
老师您好，A选项看了答案以后我能理解了，但是C选项不太明白，我是看到了原文中的newly excavated site 选了C,麻烦老师讲解一下，谢谢
