In 1990 all of the people who applied for a job at Evco also applied for a job at Radeco, and Evco and Radeco each offered jobs to half of these applicants. Therefore, every one of these applicants must have been offered a job in 1990.
The argument above is based on which of the following assumptions about these job applicants?
(A) All of the applicants were very well qualified for a job at either Evco or Radeco.
(B) All of the applicants accepted a job at either Evco or Radeco.
(C) None of the applicants was offered a job by both Evco and Radeco.
(D) None of the applicants had applied for jobs at places other than Evco and Radeco.
(E) None of the applicants had previously worked for either Evco or Radeco.

选C。我觉得是选B。

Houses built during the last ten years have been found to contain indoor air pollution at levels that are, on average, much higher than the levels found in older houses. The reason air-pollution levels are higher in the newer houses is that many such houses are built near the sites of old waste dumps or where automobile emissions are heavy.
Which of the following, if true, calls into question the explanation above?
(A) Many new houses are built with air-filtration systems that remove from the house pollutants that are generated indoors.
(B) The easing of standards for smokestack emissions has led to an increase in air-pollution levels in homes.
(C) New houses built in secluded rural areas are relatively free of air pollutants.
(D) Warm-weather conditions tend to slow down the movement of air, thus keeping pollution trapped near its source.
(E) Pressboard, an inexpensive new plywood substitute now often used in the construction of houses, emits the pollutant formaldehyde into the house.

选E。不太明白。

The most important aspect of moviemaking is conveying a scene’s rhythm. Conveying rhythm depends less on the artistic quality of the individual photographic images than on how the shots go together and the order in which they highlight different aspects of the action taking place in front of the camera.
If the statements above are true, which of the following must be true on the basis of them?
(A) The artistic quality of the individual photographic image is unimportant in movie photography.
(B) Photographers known for the superb artistic quality of their photographs are seldom effective as moviemakers.
(C) Having the ability to produce photographs of superb artistic quality does not in itself guarantee having the ability to be a good moviemaker.
(D) Movie photographers who are good at their jobs rarely give serious thought to the artistic quality of the photographs they take.
(E) To convey a scene’s rhythm effectively, a moviemaker must highlight many different aspects of the action taking place.

选C。不明白，E不行么？

Human beings can see the spatial relations among objects by processing information conveyed by light. Scientists trying to build computers that can detect spatial relations by the same kind of process have so far designed and built stationary machines. However, these scientists will not achieve their goal until they produce such a machine that can move around in its environment.
Which of the following, if true, would best support the prediction above?
(A) Human beings are dependent on visual cues from motion in order to detect spatial relations.
(B) Human beings can often easily detect the spatial relations among objects, even when those objects are in motion.
(C) Detecting spatial relations among objects requires drawing inferences from the information conveyed by light.
(D) Although human beings can discern spatial relations through their sense of hearing, vision is usually the most important means of detecting spatial relations.
(E) Information about the spatial relations among objects can be obtained by noticing such things as shadows and the relative sizes of objects.

1.
(B) All of the applicants accepted a job at either Evco or Radeco.
题目并未指出是否accept job
2.

3.
(E) To convey a scene’s rhythm effectively, a moviemaker must highlight many different aspects of the action taking place.
文中没有提及must highlight many different aspects,虽然逻辑上似乎正确但没有证据支持
4.
(C) Detecting spatial relations among objects requires drawing inferences from the information conveyed by light.
此线索叙述的实际上只是重述题干,但题目要的是额外的信息以补充论证
