Red blood cells in which the malarial-fever parasite resides are eliminated from a person’s body after 120 days. Because the parasite cannot travel to a new generation of red blood cells, any fever that develops in a person more than 120 days after that person has moved to a malaria-free region is not due to the malarial parasite.

Which of the following, if true, most seriously weakens the conclusion above?

(A) The fever caused by the malarial parasite may resemble the fever caused by flu viruses. （不相关：症状）
(B) The anopheles mosquito, which is the principal insect carrier of the malarial parasite, has been eradicated in many parts of the world. （不相关：其他传播者）
(C) Many malarial symptoms other than the fever, which can be suppressed with antimalarial medication, can reappear within 120 days after the medication is discontinued. （不相关：药物疗效）
(D) In some cases, the parasite that causes malarial fever travels to cells of the spleen, which are less frequently eliminated from a person’s body than are red blood cells. （相关：存在其他载体）
(E) In any region infested with malaria-carrying mosquitoes, there are individuals who appear to be immune to malaria. （不相关：免疫力）

When hypnotized subjects are told that they are deaf and are then asked whether they can hear the hypnotist, they reply, “No.” Some theorists try to explain this result by arguing that the selves of hypnotized subjects are dissociated into separate parts, and that the part that is deaf is dissociated from the part that replies.

Which of the following challenges indicates the most serious weakness in the attempted explanation described above?

(A) Why does the part that replies not answer, “Yes”? （相关：回答内容）
(B) Why are the observed facts in need of any special explanation? （不相关：需要解释的理由）
(C) Why do the subjects appear to accept the hypnotist’s suggestion that they are deaf? （不相关：需要解释的内容，可以被解释）
(D) Why do hypnotized subjects all respond the same way in the situation described? （不相关：回答的方式，可以被解释）

In comparison to the standard typewriter keyboard, the EFCO keyboard, which places the most-used keys nearest the typist’s strongest fingers, allows faster typing and results in less fatigue. Therefore, replacement of standard keyboards with the EFCO keyboard will result in an immediate reduction of typing costs.

(C) The number of businesses and government agencies that use EFCO keyboards is increasing each year. （不相关：使用率提高，支持）
(D) The more training and experience an employee has had with the standard keyboard, the more costly it is to train that employee to use the EFCO keyboard. （相关：有经验员工培训成本高）

When demand for a factory’s products is high, more money is spent at the factory for safety precautions and machinery maintenance than when demand is low. Thus the average number of on-the-job accidents per employee each month should be lower during periods when demand is high than when demand is low and less money is available for safety precautions and machinery maintenance.

Which of the following, if true about a factory when demand for its products is high, casts the most serious doubt on the conclusion drawn above?

(A) Its employees ask for higher wages than they do at other times. （不相关：工资，与事实抵触）
(B) Its management hires new workers but lacks the time to train them properly. （相关：新员工）
(C) Its employees are less likely to lose their jobs than they are at other times. （不相关：失业减少，人数增加）

Journalist: In physics journals, the number of articles reporting the results of experiments involving particle accelerators was lower last year than it had been in previous years. Several of the particle accelerators at major research institutions were out of service the year before last for repairs, so it is likely that the low number of articles was due to the decline in availability of particle accelerators.

Which of the following, if true, most seriously undermines the journalist’s argument?

(A) Every article based on experiments with particle accelerators that was submitted for publication last year actually was published. （不相关：排除其他发表率低，支持）
(B) The average time scientists must wait for access to a particle accelerator has declined over the last several years. （不相关：排除设备等待时间长，支持）
(C) The number of physics journals was the same last year as in previous years. （不相关：排除期刊减少，支持）
(D) Particle accelerators can be used for more than one group of experiments in any given year. （不相关：排除设备利用率低，支持）
(E) Recent changes in the editorial policies of several physics journals have decreased the likelihood that articles concerning particle-accelerator research will be accepted for publication. （相关：存在其他原因）

(A) When levels of personal retirement savings increase, consumer borrowing always increases correspondingly. （相关：存在负面效果）
(B) The increased tax revenue the government would receive as a result of business expansion would not offset the loss in revenue from personal income taxes during the first year of the plan. （不相关：税收差额）

Hotco oil burners, designed to be used in asphalt plants, are so efficient that Hotco will sell one to the Clifton Asphalt plant for no payment other than the cost savings between the total amount the asphalt plant actually paid for oil using its former burner during the last two years and the total amount it will pay for oil using the Hotco burner during the next two years. On installation, the plant will make an estimated payment, which will be adjusted after two years to equal the actual cost savings.

Which of the following, if it occurred, would constitute a disadvantage for Hotco of the plan described above?
