提纲:1The sample of the survey is not surfficiently large.
2The result of the survey does not comprehend the residents' attitude to ABC.
3The expetional service of EZ is too vague.
4who conducted the survey.
5the potentional substitution
In this letter, author recommends continuing using EZ Disposal. In order to support his recommendation, he cites the fallowing facts:(1)80percent of residents to the last year’s town survey agreed that they were satisfied with EZ’s performance.(2)EZ Disposal provides exceptional service.
First of all, author fails to inform us how many persons echoed the survey. If the sample is not large enough, the result is highly suspect. For example, if there are 10000 residents in Grove town, but only 100 persons responded the survey the result of the survey make no sense as the evidence of the conclusion at all. Lacking of information about the scale of the sample is insufficient to justify the conclusion.
Secondly, this survey only provide the residents’ view about EZ Disposal, not including their attitude about ABC Waste. So we don’t know whether the resident are as satisfied with ABC’s performance as with EZ’s. Maybe the residents who prefer EZ is even more. With out these information, it’s flippant to draw any conclusion.
.Thirdly this piece of information that EZ Disposal provides exceptional service is too vague, because it does not include the content and the value of the service. The key point is just whether the exceptional service equals $500 a month. Be facing with such a vague fact It is fallacious to draw any conclusion.
Fourthly, the arguer fail to rveal who conduced the survey, which is a key point to the survey . Maybe it is Ez disposal itself conductit. In this case the rathdom sample is hard to be ensured.EZ had incentive to select the residents who was satisfied with It.Un less the arguer exclude the posibility,the result of survey can't be plausible.
Even if EZ' service is really better than ABC, it is still fallacious to continue the contract with it. It is possible that there are other firms whose service is sperior but whose charge is more economical.In this case choosing EZ or ABC is both not rational.To render me accept his recomandation , the arguer have to exclude this pllibility..
In sum, these logical flaws are so obvious that the evidence can’t supply any powerful support to the general conclusion. In order to consolidate it the arguer have to provide fallowing information: (1) the scale of the sample(2) residents' attitude to ABC' service(3) the content and value of EZ's exceptional service(4) the people or ognization that conduced the survey(5) the potential substitution of these two firms.

Forthly, this piece of information that EZ Disposal provides exceptional service is too vague, because it does not include the content and the value of the service. It is most likely that that exceptional service is just odds and ends which do not marked good to the residents. In this case the exceptional service does not equal $500 a month.
