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.

In an experiment, volunteers walked individually through a dark, abandoned theater. Half of the volunteers had been told that the theater was haunted and the other half that it was under renovation. The first half reported significantly more unusual experiences than the second did. The researchers concluded that reports of encounters with ghosts and other supernatural entities generally result from prior expectations of such experiences.

Which of the following, if true, would most seriously weaken the researchers' reasoning?

您好，这道题目想要请王文静老师来回答一下，我是之前广州班的学生，实在不好意思又问了一道没有人问的简单题但是我真的想不懂。这个题目我选择了Before being told about the theater, the volunteers within each group varied considerably in their prior beliefs about supernatural experiences.我觉得这个答案：All of the volunteers in the first half believed that the researchers` statement that the theater was haunted was a lie.是一个抬杠类型的选项，原文说第一组的人被告知说这里面有鬼，选项说他们不信，这难道不是抬杠吗，这不是直接驳斥了论据而不是驳斥逻辑链？我觉得我选的这个正好提供了一个他因解释：这些人在进入电影院之前就已经根据他们是否相信超自然现象分组了，我后来想了想觉得这个选项是不是有gap就是他也没有说哪个组相信哪个组不相信所以她就错了，但是正确选项我感觉就是抬杠类型的选项。感谢老师的耐心解答!

Cognitive scientist: Using the pioneering work of comparative psychologist Gordon Gallup as a model, several studies have investigated animals’ capacity for mirror self-recognition (MSR). Most animals exposed to a mirror respond only with social behavior, such as aggression. However, in the case of the great apes, repeated exposure to mirrors leads to self-directed behaviors, such as exploring the inside of the mouth, suggesting that these animals recognize the reflection as an image of self. The implication of these studies is that the great apes have a capacity for self-awareness unique among nonhuman species.

The cognitive scientist makes which of the following assumptions in the argument above?

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?

b说的是ambulances这种车必须降速吗？可是原文说这个speed hump的作用就是让车降速啊，那这不就刚好符合了嘛？还有为什么不选e呢？

In response to viral infection, the immune systems of mice typically produce antibodies that destroy the virus by binding to proteins on its surface.  Mice infected with a herpesvirus generally develop keratitis, a degenerative disease affecting part of the eye.  Since proteins on the surface of cells in this part of the eye closely resemble those on the herpesvirus surface, scientists hypothesize that these cases of keratitis are caused by antibodies to herpesvirus.
 
Which of the following, if true, gives the greatest additional support to the scientists' hypothesis?

Marketing executive for Magu Corporation: Whenever Magu opens a manufacturing facility in a new city, the company should sponsor, or make donations to, a number of nonprofit organizations in that city. Doing so would improve Magu's image in the community, and thus the money spent on such charitable ventures would lead to increased sales.

Which statement would, if true, point to the most serious weakness in the marketing executive's advice?

In the major cities of industrialized countries at the end of the nineteenth century, important public places such as theaters, restaurants, shops, and banks had installed electric lighting, but electricity was in less than one percent of homes, where lighting was still provided mainly by candles or gas.

A recent poll indicates that many people in the United States hold a combination of conservative and liberal political views; i.e., they denounce big government, saying government is doing too much and has become too powerful, while at the same time supporting many specific government programs for health care, education, and the environment.
我看懂了这道题的语意，然后觉得5个选项都不合适。我觉得A错在“denounce”和“ is”上面，看起来“they denounce big government, saying government is doing too much”这句话似乎有两个谓语。但后面看了其他分析，说while作为连词连接了2个句子，表转折。所以我想请问while连接了哪两个句子呢？

Insect infestations in certain cotton-growing regions of the world have caused dramatic increases in the price of cotton on the world market.  By contrast, the price of soybeans has long remained stable.  Knowing that cotton plants mature quickly, many soybean growers in Ortovia plan to cease growing soybeans and begin raising cotton instead, thereby taking advantage of the high price of cotton to increase their income significantly, at least over the next several years.

您好，这道题目想要请王文静老师来回答一下，我是之前广州班的学生，这个题目我做对了我想问一下：这个less和lower还有greater和more之间的区别是什么？这个题目我是通过比较来排除的Bit不对Cwere不对D全都省了这里面有比较in+时间的嫌疑，比的就不是主谓了。所以想要问一下前面的标准是什么，我之前的标准是如果比较双方就是说两个数字，单纯的两个数字来比较是用lower greater的比如2比3小这里面用lower，但是如果我要是说的是这个物体比那个物体多这种概念，涉及到事情的比较的时候就用more less这种标准是对的吗？那我们的标准是什么呢？谢谢老师
