The proportion of manufacturing companies in Alameda that use microelectronics in their manufacturing processes increased from 6 percent in 1979 to 66 percent in 1990. Many labor leaders say that the introduction of microelectronics is the principal cause of the great increase in unemployment during that period in Alameda. In actual fact, however, most of the job losses were due to organizational changes. Moreover, according to new figures released by the labor department, there were many more people employed in Alameda in the manufacturing industry in 1990 than in 1979.
Which of the following, if true, would most strengthen the labor leaders’ claim concerning the manufacturing industry in Alameda?
(A) From 1979 to 1990, fewer employees of manufacturing companies in Alameda lost their jobs because of the introduction of microelectronics than did employees of manufacturing companies in the nearby community of Rockside.
(B) The figures on the use of microelectronics that were made public are the result of inquiries made of managers in the manufacturing industry in Alameda.
(C) The organizational changes that led to job losses in all sectors of the manufacturing industry in Alameda were primarily the result of the introduction of microelectronics.
(D) Figures on job losses in the manufacturing industry in Alameda for the late sixties and early seventies have not been made available.（C）
(E) A few jobs in the manufacturing industry in Alameda could have been saved if workers had been willing to become knowledgeable in microelectronics.
问的是加强，我觉得题中labor leaders的观点是the introduction of microelectronics is the principal cause of the great increase in unemployment during that period in Alameda.而后面的In actual fact是作者的论述。C加强的是作者的观点，而不是labor leaders'. 请指正。

Recent audits revealed that BanqueCard, a credit service, has erred in calculating the interest it charges its clients. But BanqueCard’s chief accountant reasoned that the profits that the company shows would remain unaffected by a revision of its clients’ credit statements to correct its previous billing errors, since just as many clients had been overcharged as undercharged.
Which of the following is a reasoning error that the accountant makes in concluding that correcting its clients’ statements would leave BanqueCard’s profits unaffected?
(A) Relying on the reputation of BanqueCard as a trustworthy credit service to maintain the company’s clientele after the error becomes widely known
(B) Failing to establish that BanqueCard charges the same rates of interest for all of its clients
(C) Overlooking the possibility that the amount by which BanqueCard’s clients had been overcharged might be greater than the amount by which they had been undercharged
(D) Assuming that the clients who had been overcharged by BanqueCard had not noticed the error in their credit bills（C）
(E) Presupposing that each one of BanqueCard’s clients had either been overcharged or else had been undercharged by the billing error
这题我选的是A，因为觉得reputation一旦破坏，client自然会减少，而公司的profit也会减少。请NN指正。
