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.

Nitrogen dioxide is a pollutant emitted by automobiles.  Catalytic converters, devices designed to reduce nitrogen dioxide emissions, have been required in all new cars in Donia since 1993, and as a result, nitrogen dioxide emissions have been significantly reduced throughout most of the country.  Yet although the proportion of new cars in Donia's capital city has always been comparatively high, nitrogen dioxide emissions there have showed only an insignificant decline since 1993.
 
Which of the following, if true, most helps to explain the insignificant decline in nitrogen dioxide emissions in Donia's capital city?
D说以前就有车安装了这个装置 所以变化不明显 E说工作温度 貌似无关

The passage suggests that the historian mentioned in the second paragraph (the highlighted text) would be most likely to agree with which of the following assertions regarding Alessandra Strozzi?
这是人人网上的一道逻辑题,分析我有点不明白,还请老师讲解一下。 答案是D,我选的是E。 我觉得D和E的性质是一样的,我觉得这两个选项都是在说另外一个因素的影响,D是light,E是the air filters变化的频率,我有点分不明白这两个选项的区别,请老师讲一讲,谢谢。 Urban air contains more sulfur dioxide than does rural air, and plants in cities typically grow more slowly than do plants in rural areas. In an experiment to see how much of the difference in growth is due to sulfur dioxide, classes in an urban and a rural school grew plants in greenhouses at their schools and filtered the greenhouse air to eliminate sulfur dioxide. Plants in the urban greenhouse grew more slowly than those in the rural greenhouse. Which of the following, if true, would it be most important to take into account in evaluating the result? (A) The urban school was located in a part of the city in which levels of sulfur dioxide in the air were usually far lower than is typical for urban areas. (B) At both schools, the plants in the greenhouses grew much more quickly than did plants planted outdoors in plots near the greenhouses. (C) The urban class conducting the experiment was larger than the rural class conducting the experiment. (D) Heavy vehicular traffic such as is found in cities constantly deposits grime on greenhouse windows, reducing the amount of light that reaches the plants inside. (E) Because of the higher levels of sulfur dioxide in the air at the urban school, the air filters for the urban school's greenhouse were changed more frequently than were those at the rural school.

Paleontologist: About 2.8 million years ago, many species that lived near the ocean floor suffered substantial population declines.  These declines coincided with the onset of an ice age.  The notion that cold killed those bottom-dwelling creatures outright is misguided, however; temperatures near the ocean floor would have changed very little.  Nevertheless, the cold probably did cause the population declines, though indirectly.  Many bottom-dwellers depended for food on plankton, small organisms that lived close to the surface and sank to the bottom when they died.  Most probably, the plankton suffered a severe population decline as a result of sharply lower temperatures at the surface, depriving many bottom-dwellers of food.
In the paleontologist's reasoning, the two portions in boldface play which of the following roles?
