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.

Charles Lindbergh, for his attempt at a solo transatlantic flight, was very reluctant to have any extra weight on his plane, he therefore refused to carry even a pound of mail, despite being offered $1,000 to do so.
老师： 这道题看了之前老师的解答，还是不理解A的逻辑为什么错。 老师给的解释是：因为他不愿意运，所以他不愿意运。 这样当然不能形成因果，我理解。 但是我在做题时读到的字面意思是：CL不愿意增加额外重量在他的飞机上，因此他拒绝携带甚至一点重量。 简单来说就是：因为不愿意运，所以就拒绝运 这样就形成了因果逻辑，就没有错了。 我的想法哪里错了？疑惑

A prominent investor who holds a large stake in the Burton Tool Company has recently claimed that the company is mismanaged, citing as evidence the company's failure to slow production in response to a recent rise in its inventory of finished products.  It is doubtful whether an investor's sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified.  It is true that an increased inventory of finished products often indicates that production is outstripping demand, but in Burton's case it indicates no such thing.  Rather, the increase in inventory is entirely attributable to products that have already been assigned to orders received from customers.
 
In the argument given, the two boldfaced portions play which of the following roles?

Political Advertisement:
 
Mayor Delmont's critics complain about the jobs that were lost in the city under Delmont's leadership.  Yet the fact is that not only were more jobs created than were eliminated, but the average pay for these new jobs has been higher than the average pay for jobs citywide every year since Delmont took office.  So there can be no question that throughout Delmont's tenure the average paycheck in this city has been getting steadily bigger.
 
Which of the following, if true, most strengthens the argument in the advertisement?
怎么能把D读成相关，而A读成无关的呢。A就是产生的jobs的average pay，D则是讲消失的jobs的average pay还扯到了citywide。这题不靠逻辑推理，仅靠有无关怎么怎么做

这道题是说x时1-8以内的正整数乘积，所以我认为2i，3k，5m，7p都应该是1-8以内的正整数，这样i,k,m,p就应该为3，1，1，1了，得出来应该是7.可答案是11，是不是我题目理解错了。

In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have significant barnacle populations, even though they seldom burrow.

Which of the following, if true, most helps to explain the surprising finding?
原文读懂了，大致是说有了burrowing可以防水，就没有B这个东西，等到螃蟹长大了，就不需要burrow，需要大量的B。但是，现在即使现在不burrow，仍然没有B，怎么解释。 我一个都连不上··选项E怎么连才通顺啊？完全没感觉···

During the month of May, crabs arrive on Delaware's beaches to lay eggs.  Certain shorebirds depend on these eggs for food during their annual spring migration to their northern breeding grounds.  Delaware's crab population has declined recently.  This decline, however, poses no serious threat to the migrating shorebird populations:  by remaining longer in Delaware, the birds will be able to eat enough crab eggs to allow them to complete their migration.
 
Which of the following, if true, most seriously weakens the argument?

Economist:  On average, the emergency treatment for an elderly person for injuries resulting from a fall costs $11,000.  A new therapeutic program can significantly reduce an elderly person's chances of falling.  Though obviously desirable for many reasons, this treatment program will cost $12,500 and thus cannot be justified.
 
Which of the following, if true, most seriously undermines the conclusion of the argument?
题干是：老年人由于摔跤导致受伤产生的急救费是11000，有一种新的治疗方案能够显著的减少老年人摔跤的机会。尽管在某些原因上是可取的，但是这个方案要花费12500，因此是不合理的。问削弱 A说参见救助方案几个月的老人比参加一年的摔跤多。无关，排除 B说住疗养院的老人比独自一人在家的摔跤少。无关，排除 C说摔跤的结果是长期的疼痛，而治疗长期疼痛的药费用并没有计算在老人摔跤所产生的急救费中。说明方案花费更高，不好，感觉是加强。就错杀了 D说新方案更关注治疗而不是药，过量用药会导致摔跤的可能性更大。无关 E说新方案的成本主要是由于专业人员的更多Visit产生的，这种成本的增长比其他因素更快。由于其他都被我肯定地排除了，就选了E 这题我花了四五分钟后还是做错了，请英老师帮我分析下思维的问题，及如何练习及改正。

A new commercial radio station in Greenfield plans to play songs that were popular hits fifteen to twenty-five years ago. It hopes in this way to attract an audience made up mainly of people between thirty-five and forty-five years old and thereby to have a strong market appeal to advertisers.
Each of the following, if true, strengthens the prospects that the radio station's plan will succeed EXCEPT:
正确答案是C，选的时候选了B，因为溜选项时我这样想，B说的是另一个地方的情况，并不代表这种情况也会适用于GREENFIELD，所以是发散了，而C的选项是说人们更多地倾向于听news不是音乐，不代表人们在计划实施后就不会听音乐，所以就排除了，我这样想错在哪儿呢？如何比较这两个选项之间的差异呢？

Unlike a female grizzly bear in the Rockies, which typically occupies a range of 50 to 300 square miles, a male's range will cover 200 to 500 and occasionally as many as 600.
