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.

Which of the following most logically completes the passage?

A recent government study links the high rates of respiratory ailments in Groverston to airborne pollutants released by the Woodco plywood manufacturing plant there. To address the problem, the government imposed strict regulations on emissions which will go into effect in four years. Although Woodco plans to cut its emissions in half two years ahead of schedule, it is unlikely that the rate of respiratory ailments will decline before the regulations go into effect, since ________.
老师,我错选了D选项。原文说削减了排放污染反而没有下降,D表达的意思是respiratory ailment 除了airborne pollutants 还有其他的原因。如果其他的原因导致的污染物增多,且其增多的量比法规削减的airborne pollutants 多,总的污染不是会增加吗?所以即使削减了排放反而污染物不可能下降。请问D错在哪里呢?

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?
老师,我错选了A选项。原文surprisingly后面说在潮汐很弱的地方这种螃蟹并没有很多的barnacle ,即使他们不挖洞。这不是排除了潮汐对barnacle 的影响吗?原文要解释的地方为什么不是这些地方即使潮汐很弱螃蟹的barnacle 很少的原因呢?A选项说潮汐并没有减少Barnacle 为什么与原文意思相反呢?并且我不能理解选E的原因。请老师解答一下

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?

Goronian lawmaker:  Goronia's Cheese Importation Board, the agency responsible for inspecting all wholesale shipments of cheese entering Goronia from abroad and rejecting shipments that fail to meet specified standards, rejects about one percent of the cheese that it inspects.  Since the health consequences and associated costs of not rejecting that one percent would be negligible, whereas the cost of maintaining the agency is not, the agency's cost clearly outweighs the benefits it provides.
 
Knowing the answer to which of the following would be most useful in evaluating the lawmaker's argument?

Community activist:  If Morganville wants to keep its central shopping district healthy, it should prevent the opening of a huge SaveAll discount department store on the outskirts of Morganville.  Records from other small towns show that whenever SaveAll has opened a store outside the central shopping district of a small town, within five years the town has experienced the bankruptcies of more than a quarter of the stores in the shopping district.
 
The answer to which of the following would be most useful for evaluating the community activist's reasoning?
听录播课时老师说C答案的逻辑是如果健康地区的破产率达到四分之一,则M地区还是很健康的,推翻了原文的结论。可是原文的主题是问M地区是否健康吗?难道不是问Save all discount department对stores 的影响吗?

Jennifer:  Video rental outlets in Centerville together handled 10,000 fewer video rentals in 1994 than in 1993.  The decline in rentals was probably due almost entirely to the February 1994 opening of Videorama, the first and only video rental outlet in the area that, in addition to renting videos, also sold them cheaply.
 
Brad:  There must be another explanation:  as you yourself said, the decline was on the order of 10,000 rentals.  Yet Videorama sold only 4,000 videos in 1994.
 
Which of the following, if true, would most seriously weaken the force of the objection that Brad presents to Jennifer's explanation?
老师 我错选了C 原文Brad 认为的应该是销售和下降的租赁存在差异.不是销售影响了租vedio 的量 要削弱他就是是销售影响了租vedio 的量.C说的是不是销售影响了租的量因为人们会和朋友借 这不是一个增强项吗?C说打折 可能其他的店租的更便宜就排除了是销售影响了租赁的量这个因素.这是我的思考过程 请老师解答一下

Studies in restaurants show that the tips left by customers who pay their bill in cash tend to be larger when the bill is presented on a tray that bears a credit-card logo. Consumer psychologists hypothesize that simply seeing a credit-card logo makes many credit-card holders willing to spend more because it reminds them that their spending power exceeds the cash they have immediately available.

Which of the following, if true, most strongly supports the psychologists’ interpretation of the studies?
老师,原文说的是pay more tips 但是这个B 选项说under financial pressure 会少付,可是原文并没有说经济压力的情况.请问您能否解答一下B 的思路呢?

Last year a record number of new manufacturing jobs were created.  Will this year bring another record?  Well, any new manufacturing job is created either within an existing company or by the start-up of a new company.  Within existing firms, new jobs have been created this year at well below last year's record pace.  At the same time, there is considerable evidence that the number of new companies starting up this year will be no higher than it was last year and there is no reason to think that the new companies starting up this year will create more jobs per company than did last year's start-ups.  So clearly, the number of new jobs created this year will fall short of last year's record.
