【正文】 ith storebought groceries could reflects the level of a certain area. () ★★★★2. The argument falsely assumes that consumers who are dissatisfied with storebought groceries are likely to grow their own vegetables instead. () ★★★★★3. The arguer fails to provide any information about what fraction of consumers buy their vegetables from supermarkets. () ★★4. The arguer fails to convince us that the gardening magazine Great Gardens is indeed popular among residents. () ★★5. We do not know the content and circulation of the magazine, thus the fact that the magazine has sold out three months in a row does not necessarily indicate that people in this area are interested in planting vegetables themselves. () ★★★6. The situation at one certain news stand does not prove that people in this area are interested in gardening. (quantity of the sample) ★★★7. The arguer fails to consider the possible cost of the proposed action. (:disadv) ★★★★—————————————————————————————— 233, （工程建設(shè)/決策/對(duì)比+并列）The following appeared in a memo from the vice president of a pany that builds shopping malls throughout the country. The surface of a section of Route 101(1), paved two years ago by McAdam Road Builders, is now badly cracked and marred by dangerous potholes. In another part of the state, a section of Route 66(1), paved by Appian Roadways more than four years ago, is still in good condition(2). Appian Roadways has recently purchased stateoftheart paving machinery, and it has hired a new qualitycontrol manager(3,4,5). Because of its superior work and mitment to quality, we should contract with Appian Roadways rather than McAdam Road Builders(9) to construct the access roads(6,8) for all(7) our new shopping malls. ★17,41,931. Only one of all roads built by each pany is pared, and only one section of each road is pared, thus we cannot evaluate the overall quality of construction of the two panies. () ★★★★2. Many other factors that would influence the condition of a road are ignored by the president. () ★★★★★3. The arguer does not provide any information about the machinery used and the status of qualitycontrol personnel at McAdam. (ex parte information) ★★★4. No information about the performance of the new qualitycontrol manager at Appian is provided. () ★★★5. Many factors besides equipment and onsite management would also affect the quality of a pavement job. () ★★★★6. Granted that the quality of routes paved by Appian is superior, we cannot guarantee Appian could also do an excellent job in constructing the access roads for shopping malls. () ★★★7. The president hastily assumes that Appian is capable of constructing the access roads of all new shopping malls. () ★★★8. The president fails to consider if Appian are willing to contract with the pany to construct access roads. (feasibility of the conclusion) ★★9. Other petent panies might be available for the president to choose from.

The author unfairly attributes the successful employment result of the laidoff employees who used Delany to Delany’s assistance. (NCR) ★★★★2. The fact that only half of the laidoff workers found jobs within a year may not result from ineffectiveness of Walsh. (NCR/) ★★★★3. Many factors could explain the differences between the employment results of using each pany. () ★★★★4. Without any parative data, we cannot determine if the employment result of workers who use Walsh eight years ago are poor. (lack of parison) ★★★★5. Many conditions would have changed during the past eight years. (P→C) ★★★6. The size of staff and number of branch offices do not necessarily indicate the quality and effectiveness of a pany’s service. () ★★★★7. A bigger staff may just indicate that the efficiency at Delany is lower. (negative evidence) ★★8. There is no significant difference between finding job within six months and within nine months. () ★★9. Without detailed description of jobs found by Delany’s clients and Walsh’s clients respectively, and without more information about their clients, we cannot evaluate which pany is more effective. () ★★★★10. A single year39。 at the large, forprofit hospital in the nearby city of Megaville, the average patient stay is six days(1). Also, the cure rate(2) among patients in the Saluda hospital is about twice(3) that of the Megaville hospital. The Saluda hospital has more employees per patient(5) than the hospital in Megaville, and there are few plaints(6) about service at the local hospital(4). Such data indicate that treatment in smaller, nonprofit hospitals(8) is more economical(7) and of better quality than treatment in larger, forprofit hospitals. ★★1. The time length of a patient’s stay is not a good indication of the quality of treatment in the hospital. () ★★★★2. Other factors might also explain the shorter length of patient stay and higher cure rate in the Saluda hospital. () ★★★★★3. We do not know the severity of illness among patients in the Saluda hospital and in Megaville hospital, thus cannot evaluate the cure rate in the two hospitals. () ★★★★4. More employees per patient and few plaints do not necessarily indicate that treatment in Saluda hospital is better than that in Megaville hospital. () ★★★★5. A higher employeepatient ratio may just indicate organizational inefficiency at Saluda. (negative evidence) ★★★6. Without the total number of patients going to each hospital, we cannot evaluate what percentage of their patients plained. () ★★★7. The author fails to provide the actual expenditures of patients in the two hospitals, thus the assumption that treatment in smaller, nonprofit hospital is more economical is unwarranted. () ★★8. The author hastily generalizes that treatment in other smaller, nonprofit hospitals will necessarily be more economi
