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.

Colorless diamonds can command high prices as gemstones. A type of less valuable diamonds can be treated to remove all color. Only sophisticated tests can distinguish such treated diamonds from naturally colorless ones. However, only 2 percent of diamonds mined are of the colored type that can be successfully treated, and many of those are of insufficient quality to make the treatment worthwhile. Surely, therefore, the vast majority of colorless diamonds sold by jewelers are naturally colorless.

A serious flaw in the reasoning of the argument is that

Which of the following most logically completes the reasoning?
 
Either food scarcity or excessive hunting can threaten a population of animals.  If the group faces food scarcity, individuals in the group will reach reproductive maturity later than otherwise.  If the group faces excessive hunting, individuals that reach reproductive maturity earlier will come to predominate.  Therefore, it should be possible to determine whether prehistoric mastodons became extinct because of food scarcity or human hunting, since there are fossilized mastodon remains from both before and after mastodon populations declined, and ______.

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.

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.

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
