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.

Enforcement of local speed limits through police monitoring has proven unsuccessful in the town of Ardane. In many nearby towns, speed humps (raised areas of pavement placed across residential streets, about 300 feet apart) have reduced traffic speeds on residential streets by 20 to 25 percent. In order to reduce traffic speed and thereby enhance safety in residential neighborhoods, Ardane's transportation commission plans to install multiple speed humps in those neighborhoods.

Which of the following, if true, identifies a potentially serious drawback to the plan for installing speed humps in Ardane?

文章关注的是限速进而减少危险，b选项关注的不是速度问题是一些特殊车辆要减速的问题，而这些问题不是由速度引起的是耽误了救援，而我选择的D当时的思路是，开汽车的人没有意识到减速带就不会减速，就不能减速进而减少安全问题起到了weaken的作用@英吉老师

Telomerase is an enzyme that is produced only in cells that are actively dividing.  For this reason it is generally absent from body tissues in adults.  Bone marrow is an exception to this rule, however, since even in adults, bone marrow cells continually divide to replace old blood cells.  Cancers are another exception, because their cells are rapidly dividing.
 
The information provided most strongly supports which of the following?

In the decimal representation of x, where 0＜x ＜1, is the tenths digit of x nonzero?

(1) 16x is an integer.

(2) 8x is an integer.
请问徐小梅老师，本题还是没有很理解您在上面的解答和题目的意思：“因为a,b本身已经是互质的，所以16*a/b想要是整数，说明只能是16约分掉b，也就是说b里面只能有2这个质因数，而且2的个数是从2一次方到2的4次方之间，所以a/b就相当于【a*1/16；a*1/2】；”为什么ab肯定是互质的呢？16=2的四次方这点可以理解，所以a/b就相当于【a*1/16；a*1/2】这句话和后面那部分对应的解释还是看得有点迷迷糊糊的

请问张慧雯老师，我觉得本题的考点应该是句间关系和句子的功能的考察， 他是这句话的例子，应该会支持这句话的观点： Scientists generally credit violent collisions between tectonic plates, the mobile fragments of Earth's rocky outer shell, with sculpting the planet's surface, 但是他后面有个转折However, plate tectonics cannot fully explain certain massive surface features所以这个例子应该和后面那个句子的意思是相反关系？是不是如果是e 问题出在第一是plate不能解释而不是科学家不能解释，所以对象错了?

Vorland's government is planning a nationwide ban on smoking in restaurants.  The objection that the ban would reduce restaurants' revenues is ill founded.  Several towns in Vorland enacted restaurant smoking restrictions five years ago.  Since then, the amount the government collects in restaurant meal taxes in those towns has increased 34 percent, on average, but only 26 percent elsewhere in Vorland.  The amount collected in restaurant meal taxes closely reflects restaurants' revenues.
 
Which of the following, if true, most undermines the defense of the government's plan?

Though sucking zinc lozenges has been promoted as a treatment for the common cold, research has revealed no consistent effect.  Recently, however, a zinc gel applied nasally has been shown to greatly reduce the duration of colds.  Since the gel contains zinc in the same form and concentration as the lozenges, the greater effectiveness of the gel must be due to the fact that cold viruses tend to concentrate in the nose, not the mouth.
 
In order to evaluate the argument, it would be most helpful to determine which of the following?
请问张慧雯老师，本题说l是治疗感冒的一种方式，现在发现有个z效果更好，但是她两的成分是一样的，所以后面的重点就讨论了病毒是在鼻子集中还是嘴巴集中的问题。然后就选了b，不明白这个逻辑和activity of the zinc有什么关系，选b的原因是不是还是我只关注了结论？

Aroca City currently funds its public schools through taxes on property.  In place of this system, the city plans to introduce a sales tax of three percent on all retail sales in the city.  Critics protest that three percent of current retail sales falls short of the amount raised for schools by property taxes.  The critics are correct on this point.  Nevertheless, implementing the plan will probably not reduce the money going to Aroca's schools.  Several large retailers have selected Aroca City as the site for huge new stores, and these are certain to draw large numbers of shoppers from neighboring municipalities, where sales are taxed at rates of six percent and more.  In consequence, retail sales in Aroca City are bound to increase substantially.
 
In the argument given, the two potions in boldface play which of the following roles?
请教张慧雯老师，这题我觉得结论句是 In consequence, retail sales in Aroca City are bound to increase substantially.黑体2，然后两个黑体之间夹着一个 Nevertheless, 应该是意思相反的，排除b和c，然后再加上 the critics are correct on this point. 所以排除d， 然后ae里面纠结，对于黑体1那部分的解释也挺晕的。
