17.The following appeared in a letter to the editor of the Walnut Grove town newspaper.
"Walnut Grove's town council has advocated switching from EZ Disposal (which has had the contract for trash collection services in Walnut Grove for the past ten years) to ABC Waste, because EZ recently raised its monthly fee from $2,000 to $2,500 a month, whereas ABC's fee is still $2,000. But the town council is mistaken; we should continue using EZ. EZ collects trash twice a week, while ABC collects only once. Moreover, EZ-which, like ABC, currently has a fleet of 20 trucks have ordered additional trucks. Finally, EZ provides exceptional service: 80 percent of respondents to last year's town survey agreed that they were 'satisfied' with EZ's performance."
The speaker conclude that we should continue using EZ instead of ABC and the speaker point out three evidences to support the EZ's superiority: first, the more frequency of trash collection services; second, the larger amount of trucks; third, the good reflection of the service. Besides, the only defect is the high price and it indeed deserves the sum. Careful scrutiny of the argument exposes several logical flaws, which render it unconvincing.
First of all, twice a week's trash collection cannot equate a more thorough clearing up. There is not concrete evidence about the instance of the trash. If the waste is not so heavy, only one time to collect it is sufficient every week. The competence of the every time to do the job is not mentioned at all. For instance, the workers of the ABC Company is more skillful than the EZ's, one time per week will be enough. Moreover, perhaps the devices of ABC are more efficient and the degree of the clean is more thorough and thus the ABC service may take a long time every time. In these cases, we cannot safely support the degree of the clean.
Secondly, the order of 20 additional trucks of EZ Disposal scarcely means a more efficient service. For instance, they only order 20 trucks and cannot buy them for the sack of money shortage. Even if they indeed buy these trucks, maybe they power of cleaning is not enough to burden the whole town's work. Moreover, after this fetch in the truck, no evidence shows that the competence of the EZ will exceed the work of ABC Waste.
Thirdly, the speaker cite the survey to prove EZ' service has satisfied the residents, but we still cannot draw the conclusion. For one thing, the EZ Disposal serviced the residents 10 years and thus the inclination to continue it may stem from a credit of familiarity. If they have tried the ABC service, they may find it better and change their attitude. For the other thing, credibility of the survey lacks of evidence. If the survey only includes the ones who are satisfied, the remains' opinion will be neglected. Moreover, 80 percent of respondents are satisfying means there are still 20 percent are not. Perhaps, the switching will satisfy all the residents.
Finally, the increase of money should be taken into consideration. Maybe the town has suffered from a economy depression, and many residents cannot afford such a high price. If so, better service will give way to lower pay.
In sum, the speaker's conclusion is logically indefensible the speaker should provide more credited evidence to bolster it. |
