Augu原文
  The following appeared ina memo from the new vice president ofSartorian, a company thatmanufactures men’s clothing.   “Five years ago, at atime when we had difficulty obtaining reliable supplies of high-quality woolfabric, we discontinued production of our popular alpaca overcoat. Now that wehave a new fabric supplier, we should resume production. Given the outcry fromour customers when we discontinued this product and the fact that none of ourcompetitors offers a comparable product, we can expect pent-up consumer demand forour alpaca coats. Due to this demand and the overall increase in clothingprices, we can predict that Sartorian’s alpaca overcoats will be moreprofitable than ever before.     “Write a response inwhich you discuss what questions would need to be answered in order todecide whether the prediction and the argument on which it is based arereasonable. Be sure to explain how the answers tothese questions would help to evaluate the prediction.”;   In this argument ,the author concludes that Sartorian’salpacaovercoats will be more profitable than ever before.To strenghen this conclusion,the arguer claims that the company has a new fabric supplier to providereliable supplies of high-quality wool fabric .The arguer also cites sopportingevindence indicating that there will be pent-up customer demand for alpacaovercoat .Furthermore,he points out that the price of most types of clothinghas risen in each of the past five years.As first glance,the argument might besomewhat reasonable ,but close scrutiny reveals that it contains severalunconvincing assumptions and is therefore unpersuasive. First of all,the arguer claims that the company discontinuedeproduction of alpaca overcoat without reliable supplies of high-quality woolfabric five years ago ,and automatically assumes that it should resumeproduction because  there is a newsupplier now.The argument suffers from a fallacy of “all things are equal”.Theauthor assumes without justification that during the five-year peroid all otherbackground conditions possible affecting the overcoat production remainedunchanged.Such conditions include ,such as the changing investment cost ,or thedifference in the desirability of the two moment.Thus, without establishingthat all other factors affecting the feasibility of the production ,the authorcannot convince me that the factory should resume the prodution suspended fiveyears ago. Second,the author unfairly assumes that since the five-yearsuspended alpaca overcoat production and no competitor making the sameovercoat,there will be pent-up customer demand.The assumption might beproblematic in two aspects.The arguer obviously overlooks other possibleresults from the suspended production .Perhaps, the customers transfer theirdemands from the duluxe overcoats to the other types of clothing.Lickwise,thearguer also neglects the other plausible reasons that the major competitordoesn’t pruduce alpaca overcoat ang longer .One possible account is ,forexample, no demand for this overcoat that leads the competitor to stop the production.Therefore, without providing morepowerful information to prove that there will be pent-up customer demand ,theauthor cannot rely on this limited evidence to support his claim. Third,one problem with the argument is that it assumes that thetrends  that price of most types ofclothing have risen in each of the past five years applies equally to thealpaca overcoat.Yet the author provides no evidence to support thisassumption.It is quite possible that the alpaca overcoat doesn’t follow thisgeneral trends.For that matter,the price trends of the overcoat  might be just the opposite .Without rullingout such possibilities ,the author cannot justifiably conclude that the priceof the alpaca overcoat has risen in the past five years. To sum up ,the arguer’s prediction that the Sartorian’s alpacaovercoats will be more profitable than ever before is not well supported as itstands .To bolster it the author must provide more imformation ,such as thechanges of the background conditions during the five yearsperoid.Additionally,to better assess the problem ,I would also need to know thedemand for the overcoat and the price trends of it . |
