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.

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?
In terrestrial environments， gravity places special demands on the cardiovascular systems of animals. Gravitational pressure can cause blood to pool in the lower regions of the body， making it difficult to circulate blood to critical organs such as the brain. Terrestrial snakes， in particular， exhibit adaptations that aid in circulating blood against the force of gravity. 　　The problem confronting terrestrial snakes is best illustrated by what happens to sea snakes when removed from their supportive medium. Because the vertical pressure gradients within the blood vessels are counteracted by similar pressure gradients in the surrounding water， the distribution of blood throughout the body of sea snakes remains about the same regardless of their orientation in space provided they remain in the ocean. When removed from the water and tilted at various angles with the head up， however， blood pressure at their midpoint drops significantly， and at brain level falls to zero. That many terrestrial snakes in similar spatial orientations do not experience this kind of circulatory failure suggests that certain adaptations enable them to regulate blood pressure more effectively in those orientations. 　　One such adaptation is the closer proximity of he terrestrial snake's heart to its head， which helps to ensure circulation to the brain， regardless of the snake's orientation in space. The heart of sea snakes can be located near the middle of the body， a position that minimizes the work entailed in circulating blood to both extremities. In arboreal snakes， however， which dwell in trees and often assume a vertical posture， the average distance from the heart to the head can be as little as 15 percent of overall body length. Such a location requires that blood circulated to the tail of the snake travel a greater distance back to the heart， a problem solved by another adaptation. When climbing， arboreal snakes often pause momentarily to wiggle their bodies， causing waves of muscle contraction that advance from the lower torso to the head. By compressing the veins and forcing blood forward， these contractions apparently improve the flow of venous blood returning to the heart. 7. The primary purpose of the third paragraph is to 　　(A) Introduce a topic that is not discussed earlier in the passage 　　(B) Describe a more efficient method of achieving an effect discussed in the previous paragraph 　　(C) Draw a conclusion based on information elaborated in the previous paragraph 　　(D) Discuss two specific examples of phenomena mentioned at the end of the previous paragraph 　　(E) Introduce evidence that undermines a view reported earlier in the passage

A New York City ordinance of 1897 regulated the use of bicycles, mandated a maximum speed of eight miles an hour, required of cyclists to keep feet on pedals and hands on handlebars at all times, and it granted pedestrians right-of-way.
因为grant的逻辑发起者未变，所以不用加it，排除了A和C。然后因为regulate的发起者应该是ordiance，是法令管理而不是被管理，所以选择了regulating，排除了B。剩下了D和E两个选项，觉得应该是法令要求cyclists，而不是法令被要求cyclists，就选了D。 做完后，回看错题的时候，发现做题过程中没有想到require of 和require to的区别，D和E选项是否可以直接用require sb to do选择E。

When a polygraph test is judged inconclusive, this is no reflection on the examinee.  Rather, such a judgment means that the test has failed to show whether the examinee was truthful or untruthful.  Nevertheless, employers will sometimes refuse to hire a job applicant because of an inconclusive polygraph test result.
