General manager: Butthat is not a good enough rea son. We can simply hire only people who already know how to usethe Microton computer. Which of the following, if true, most seriously undermines the general manager's objection to the replacement of Microton computers with Vitechs? (Al Currently all employees in the company are required to attend workshops on how to use Microton computers in new applications. (8) Once employees learn how to use a computer, theytend to change employers more readily than before. (C) Experienced users of Microton computers command much higher salaries than do prospective employees who have no experience in the use of computers.

50. Crops can betraded on the futures market before they are harvested. If a poor corn harvest is predicted, prices of corn futures rise; if a bountiful corn harvest is predicted, prices of corn futures fall. This morning meteorologists are predicting much-needed rain for the corn-growing region starting tomorrow. Therefore, since adequate moisture is essential for the current crop's survival, prices of corn futures will fall sharply today. Which of the following, if true, most weakens the argument above? (A) Corn that does not receive adequate moistureduring its critical pollination stage will not produce a bountiful harvest. (8) Futures prices for corn have been fluctuating more dramatically this season than last season. (C) The rain that meteorologists predicted for tomorrow is expected to extend well beyond the corn-growing region. (D) Agriculture experts announced today that a disease that has devastated someof the corn crop will spread widely before the end of thegrowing season. (E) Most peoplewhotrade in corn futures rare ly take physical possession of the corn theytrade.
51. Acompany plans to develop a prototype weeding machine that uses cutting blades with optical sensors and microprocessors that distinguish weeds from crop plants by differences in shade of color. The inventor of the machine claims that it will reduce laborcosts by virtually eliminating the need for manual weeding. Which of the following is a consideration in favor of the company's implementing its plan to develop the prototype? (A) There is a considerable degree of variation in shade of color between weeds of different species. (8) The shade of color of some plants tends to change appreciably over the course of their growing season. (e) When crops are weeded manually, overall size and leaf shape are taken into account in distinguishing crop plants from weeds. (0) Selection and genetic manipulation allow plants of virtually any species to be economically bred to have a distinctive shade of color without altering their other characteristics. (E) Farm laborers who are responsible for the manual weeding of crops carry out other agricultural duties at times in the growing season when extensive weeding is not necessary.
52. The interview is an essential part of a successful hiring program because, with it, job applicants who have personalities that are unsuited to the requirements of the job will be eliminated from consideration . The argument above logically depends on which of the following assumptions? (A) A hiring program will be successful if it includes interviews. (8) The interview is a more important part of a successful hiring program than is the development of a job description. (e) Interviewers can accurately identify applicants whose personalities are unsuited to the requirements of the job. (D) The only purpose of an interview is to evaluate whether job applicants' personalities are suited to the requirements of the job. (E) The fit of job applicants' personalities to the requirements of the job was once the most important factor in making hiring decisions.
AA：：The following appeared as part of a recommendation from the business manager of a department store. “Local clothing stores reported that their profits decreased, on average, for the three-month period between August 1 and October 31. Stores that sell products for the home reported that, on average, their profits increased during this same period. Clearly, consumers are choosing to buy products for their homes instead of clothing. To take advantage of this trend, we should reduce the size of our clothing departments and enlarge our home furnishings and household products departments.”
提供观点： 1、衣帽部利润↓和家具部利润↑同时发生但不一定有必然联系 2、三个月的时间太短不能用来得出结论 3、过去的趋势不一定能保证未来走向 4、样本不具有代表性 1、A period of three month is too short to draw a general conclusion of the overall trend. 2、The past three months' trend does not guarantee the same in the future. 3、Whether the reports from the local clothing stores and stores that sell products for the home are reliable or not are still open to doubt, thus making the author's suggestion groundless.

AA： 1.the fact that local clothing store profits decreased for 3 months is not sufficient to say that its profits will continue decrease in the following month---> there may some other reasons for the low profits recently. 2.stores sales more home products than the cloth does not mean people prefer to by home products-->may be because the home products have more deal. 3.reduce the size of the clothing department and enlarge the size of the home products department may not a wise decision--> there may some more additional cost.
