The following appeared in a letter from a homeowner to a friend.
“Of the two leading real estate firms in our town— Adams Realty and Fitch Realty— Adams Realty is clearly superior. Adams has 40 real estate agents; in contrast, Fitch has 25, many of whom work only part-time. Moreover, Adams' revenue last year was twice as high as that of Fitch and included home sales that averaged $168,000, compared to Fitch's $144,000. Homes listed with Adams sell faster as well: ten years ago I listed my home with Fitch, and it took more than four months to sell; last year, when I sold another home, I listed it with Adams, and it took only one month. Thus, if you want to sell your home quickly and at a good price, you should use Adams Realty.”
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted.
五問:
(1)“Adams has 40 real estate agents; in contrast, Fitch has 25, many of whom work only part-time. Moreover, Adams' revenue last year was twice as high as that of Fitch and included home sales that averaged $168,000, compared to Fitch's $144,000”和“ten years ago I listed my home with Fitch, and it took more than four months to sell; last year, when I sold another home, I listed it with Adams, and it took only one month”是事實(shí),“Thus, if you want to sell your home quickly and at a good price, you should use Adams Realty”是結(jié)論,值得反駁嗎?
(2)數(shù)目和質(zhì)量可以同等比較嗎?數(shù)目越多,質(zhì)量就一定越高嗎?例如: Adams的 40個(gè)房地產(chǎn)代理的工作經(jīng)驗(yàn)可能不及 Fitch的 25個(gè)代理的工作經(jīng)驗(yàn)豐富。另外,正式員工的工作能力一定比兼職員工強(qiáng)嗎?
(3)去年的售價(jià)高,今年的售價(jià)就一定高嗎?平均值能在任何情況下都代表個(gè)體值嗎?是否有可能 Fitch的銷售量更多,從而拉低了平均售價(jià)呢?
(4)作者使用兩個(gè)不同年份的房屋的售出速度來對比兩家代理商的房屋售出速度,這樣是正確的嗎?是否犯了時(shí)間軸論證的錯(cuò)誤?十年之后, Fitch公司是否可能也取得了發(fā)展?
(5)文中對兩家代理商的對比,是否將所有方面都涵蓋了?你能否羅列一兩個(gè)可供比較的方面?例如:兩家銷售的房屋類型、地段等。
