     By citing that EZ ,which will have more trucks than ABC, collects trash twice per week more than ABC' once and 80 percent of the respondents claimed they were satisfied with EZ, the author wants to convince us that Walnut Grove(WG) town should continue using EZ as their trash disposer. However, after taking a thoroughly examination, the argument is weakened in several points.

    On the whole, the author implies us that EZ's performance merits the 500 dollar's surcharge. This is what the entire argument is based on. Yet ,being lacking in more detailed information, the assumption or implication is soundless.The author implies us that if ABC is to collect twice per week,ABC will charge $4000 while EZ 'only' charges $2500.So ,EZ is obviously deserved to choose.However,the arguer fails to provide the details about the 2 company's service. It’s quite possible that ABC uses a more advanced and environmentally harmless technique to deal with the trash while EZ just burn or bury it. Thus considering the saved expenditure in environmental protection, ABC may be a much smarter choice.So, without supplying more details about the 2 company's services, the assumption is groundless.

     Secondly, ignoring other possible alternatives, the author simply equates more trucks with better performance. Yet no evidence has shown that EZ will use these additionally ordered trucks to improve its performance in WG.Further more, it’s equally possible that these trucks will be used to expand EZ's service to other towns or cities. If that's the case, these trucks are meaningless to WG.Also, if 20 trucks are enough for the collection in WG, there’s no reason to claim more trucks will have better performance than ABC. Without ruling out these possibilitis, the claim is weakened.

     Finally, the survey results actually contribute little in proving EZ is a better choice even when EZ charges 500 dollars more. Even though 80% respondents feel satisfied with EZ, we still can't say EZ will do better than ABC .For 10 years, people in WG have already been used to EZ being their trash disposer.To take a step further, they actually have no idea about whether other company's performance will be better or not. Maybe when WG choose ABC, more respondents will admit they are satisfied. Even if ABC has fewer supporters, is EZ’s performance worthy of the extra $500 ? It still needs to be evaluated statistically. So, the mere fact that the survey provides does nothing in bolstering the argument.

For the reasons above,the argument is not strongly surpported.In order to convince us WG town should continue using EZ, the author should provide more details and statistics for us to evaluate the claim all-sidedly.
