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.

According to the passage, the anatomical evidence provided by the preserved soft bodies of conodonts led scientists to conclude that
能麻烦请Tina老师回答下吗 谢谢 这篇文章我读的框架是：Conodont这个东西发现了，然后科学家就说这个东西能帮他们研究vertebrate skeleton。第二段：两方科学家讨论vs是捕食者的进化过程，其中说了牙齿、骨头什么的（只看出来是两方对立。细节没太懂）第三段：忽然说一个肌肉，不知道为什么要说这个段落见关系不太明白。结论我读的是某种动物长了牙齿，为的就是捕食，不是防御。 第一道阅读我看的关键词是evidence和conclude，但是全篇都是围绕这个evidence的，我就觉得conclude应该是更重要，但我读的前文的结论好像答案里面没有，ABCD我觉得太细节了，只有E面积大，就选的E 第二题：他问第二段目的，我看问目的，就看了第一段最后一句：科学家发现个化石，然后通过化石研究好多，就选了A。我也知道第二段在对比两方观点，是E选项的意思，但是我觉得这是内容，而不是题干serves primarily的含义。

Analytical!
文章：According to many analysts, labor-management relations in the United States are undergoing a fundamental change: traditional adversarialism is giving way to a new cooperative relationship between the two sides and even to concessions from labor. These analysts say the twin shocks of nonunion competition in this country and low-cost, high-quality imports from abroad are forcing unions to look more favorably at a variety of management demands: the need for wage restraint and reduced benefits as well as the abolition of "rigid" work rules, seniority rights, and job classifications. Sophisticated proponents of these new developments cast their observations in a prolabor light. n return for their concessions, they point out, some unions have bargained for profit sharing, retraining rights, and job--security guarantees. Unions can also trade concessions for more say on the shop floor, where techniques such as quality circles and quality-of-work­ life programs promise workers greater control over their own jobs. Unions may even win a voice in investment and pricing strategy, plant location, and other major corporate policy decisions previously reserved to management. Opponents of these concessions from labor argue that such concessions do not save jobs, but either prolong the agony of dying plants or finance the plant relocations that employers had intended anyway. Companies make investment decisions to fit their strategic plans and their profit objectives, opponents point out, and labor costs are usually just a small factor in the equation. Moreover, unrestrained by either loyalty to their work force or political or legislative constraints on their mobility, the companies eventually cut and run, concessions or no concessions. Wage-related concessions have come under particular attack, since opponents believe that high union wages underlay much of the success of United States industry in this century. They point out that a long-standing principle, shared by both management and labor, has been that workers should earn wages that give them the income they need to buy what they make. Moreover, high wages have given workers the buying power to propel the economy forward. f proposals for pay cuts, two-tier wage systems, and subminimum wages for young workers continue to gain credence, opponents believe the U.S. social structure will move toward that of a less-developed nation: a small group of wealthy investors, a sizable but still minority bloc of elite professionals and highly skilled employees, and a huge mass of marginal workers and unskilled laborers. Further, they argue that if unions willingly engage in concession bargaining on the false grounds that labor costs are the source of a company's problems, unions will find themselves competing with Third World pay levels-a competition they cannot win. 想请问郭老师，这题opponents观点是在第三段，但是原文和选项要怎么对照呢...怎么从观点看出态度？

Fossils of the arm of a sloth found in Puerto Rico in 1991, and dated at 34 million years old, made it the earliest known mammal of the Greater Antilles Islands.

In parts of South America, vitamin-A deficiency is a serious health problem, especially among children.  In one region, agriculturists are attempting to improve nutrition by encouraging farmers to plant a new variety of sweet potato called SPK004 that is rich in beta-carotene, which the body converts into vitamin A.  The plan has good chances of success, since sweet potato is a staple of the region's diet and agriculture, and the varieties currently grown contain little beta-carotene.
 
Which of the following, if true, most strongly supports the prediction that the plan will succeed?
想请问TINA老师，这题我认为the plan will succeed是指improve nutrition，所以要support这个结论的选项应该和提高营养物质有关，所以第一眼看到A选项关于growing conditions是完全没有感觉的，觉得是个无关选项。请问老师我的思路有什么问题呢？

Last August the XT chain of gasoline stations had a temporary sales promotion in effect In the promotion , any customer who made a purchase of ten or more gallons of gasoline was entitled to a tree car wash . For the month of August , XT experienced a ten percent increase in gasoline sales as compared to sales in August the previous year .so evidently the promotion was successful as a means of boosting sales.
 
In evaluating the argument , it would be most helpful to answer which of the following ?
想请问TINA老师这题。原文逻辑链是 有了promotion后sales上升了-->promotion是使sales增加的好方法。我BDE都排除了，选了C，觉得他意思在说没了这个promotion后看看顾客还会不会买，我觉得这个选项很好...反而A选项我一看就排除了，觉得all gasoline stations是无关选项。请老师指正。

Excavations of the Roman city of Sepphoris have uncovered numerous detailed mosaics depicting several readily identifiable animal species:  a hare, a partridge, and various Mediterranean fish.  Oddly, most of the species represented did not live in the Sepphoris region when these mosaics were created.  Since identical motifs appear in mosaics found in other Roman cities, however, the mosaics of Sepphoris were very likely created by traveling artisans from some other part of the Roman Empire.
 
Which of the following is an assumption on which the argument depends?
想请问TINA老师，这题我看几个错误选项都觉得对。我觉得assumption题的选项应该和条件和结论都有关系吧，条件是那个motif出现在其他地方，结论是马赛克是由旅游的artisans带来的。A选项说马赛克的石头不是本地的，我感觉相关；B选项说马赛克上的物种不是来自同一个地方的，我也觉得相关；C、D选项可以排除；E选项说住在不同地方的artisans对马赛克不熟悉，我觉得原文不关心熟不熟悉这个事情，感觉是无关的，但是答案选E。麻烦老师讲解一下？

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.
 
Which of the following, if true, most seriously undermines the argument?
想请问TINA老师，我这题做了几次都把B选项直接排除了，我读出来意思是那个limitation导致捕猎提前结束已经很久了，所以第一次做题直接当成无关选项排除了。后来几次做题都会特别留意这个选项，但总会把选项理解成那个限制是有效果的，捕猎总能因此提前结束，我是语法出了问题吗...
