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.

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.

Heavy snow fall in the Sierra Nevada Mountains is usually preceded by subzero temperatures in northwestern Canada. When snow fall is high in Canada’s northwestern provinces, the same storm typically produces heavy snows in the Sierra Nevadas. Therefore, subzero temperatures cause winter snow storms to rebuild as they move down from Canada to the Sierra Nevadas.

The first African slaves were brought to the Americas in the early 1600s, where their labor was used primarily for agricultural and household purposes. The institution of slavery in the New World presupposes not only the existence of slaves and owners, but also a system of laws in place which recognized and protected the practice of slavery. However, laws were not enacted, for example, declaring slaves the personal property of their owners and imposing punishments upon those who aided slaves in escape, until many years later.
If the sentences in the passage above are true, then they support which one of the following statements?

Certain politicians in the country of Birangi argue that a 50 percent tax on new automobiles would halt the rapid increase of automobiles on Birangi's roads and thereby slow the deterioration of Birangi's air quality.  Although most experts agree that such a tax would result in fewer Birangians buying new vehicles and gradually reduce the number of automobiles on Birangi's roads, they contend that it would have little impact on Birangi's air-quality problem.
 
Which of the following, if true in Birangi, would most strongly support the experts' contention about the effect of the proposed automobile tax on Birangi's air-quality problem?
选的e，感觉说的是少的那些车并不会造成太多的air pollution，所以对空气质量的影响不大。我觉得是我对The scrapping of automobiles 理解有问题。 现在看d觉得也对，但是不知道怎么从d和e中选，希望老师给讲一下。

When storing Renaissance oil paintings, museums conform to standards that call for careful control of the surrounding temperature and humidity, with variations confined within narrow margins.  Maintaining this environment is very costly, and recent research shows that even old oil paint is unaffected by wide fluctuations in temperature and humidity.  Therefore, museums could relax their standards and save money without endangering their Renaissance oil paintings.

In general, jobs are harder to get in times of economic recession because many businesses cut back operations.  However, any future recessions in Vargonia will probably not reduce the availability of teaching jobs at government-funded schools.  This is because Vargonia has just introduced a legal requirement that education in government-funded schools be available, free of charge, to all Vargonian children regardless of the state of the economy, and that current student-teacher ratios not be exceeded.
 
Which of the following, if true, most strengthens the argument?

Diseases have always plagued the earth’s living organisms. Scientists believe that huge numbers of plant and animal diseases have developed and been eradicated naturally over time. This ongoing emergence and disappearance of diseases is ignored by those who blame the widespread incidence of cancer entirely upon man’s alteration of naturally occurring substances to, for instance, produce bigger and better food sources. For example, some claim that the use of hormones to increase meat production heightens the risk of cancer in people who eat meat. People who hold this view need to accept the fact that even if cancer was not such a prevalent disease, another disease would have arisen naturally to take its place.

Which one of the following identifies a flaw in the passage’s reasoning? A. The writer wrongly assumes that the use of hormones in meat production never has an effect upon people who eat meat. B. The writer ignores the fact that scientists are developing cures for some types of cancer. C. The writer does not consider the fact that a number of diseases have not yet been discovered. D. While the writer identifies a group that believes cancer is caused by man’s interference with natural forms of food production, he does not identify or recognize scientists who disagree with this contention. E. The author does not acknowledge that man’s alteration of naturally occurring substances might trigger the emergence of new diseases.
