Argument 71
In the letter, the author states the traffic problem of Waymarsh and recommends the city to implement the method of encouraging people to ride instead of driving, which has been proved successful in Garville last year. However, by supporting his claim, the author has made a series of assumptions that is unwarranted. To bolster the author’s recommendation, more evidences need to be provided.
To begin with, the author cited the policy of Garville to encourage people to ride in attempt to relieve the pressure of driving traffic. To prove that the implementation of such policy has reduced traffic jam, the author cited the respond form some residents in Garville. However, we find no information to prove that the responds are statistically sufficient and representative of the overall driving population in Garville. Perhaps only people who drive on certain roads that has relatively good condition has answer to the author's survey. Without evidence to prove the success of the Garville's method, it would be hasty to recommend that Waymarsh implement the similar policy.
Even if the Garville's method has proved to be successful, the author futher assumes that the Garville's approach would work similarly on Waymarsh traffic problem. Yet such assumption is problematic for the author overlooks the possible differences between Waymarsh and Garville. Perhaps people in Waymarsh are not willing to ride to work and such encouragement would not work on them, or perhaps the length of driving to work of the Waymarsh residents are too long to ride. Without accounting for such differences, the author's conclusion is unjustifiable.
Lastly, the author assumes that people in Waymarsh would not prefer the plan of building new roads by mentioning the fact that the constructions are too expensive. Yet the author provide no base for such assumption. It is entirely possible that the residents in Waymarsh are well in-come families and will not consider the construction a heavy financial burdon, or their concern on resolving the traffic problem are prior to their concern on public funding burden. To better support his assumption, a survey on the residents’ opinion on the construction and data including the expense of construction and the average income of Waymarsh residents would be in great help.
To sum up, the author's recommendation are based on a series of assumptions that are lack of evidences. To make a firm statement, the author needs to provide evidences that the responds of the Garville's residents are statistically significant and representative. To make a more cogent conclusion, information on the differences of Waymarsh and Garville and data of the construction expense and Waymarsh residents' income would be appreciated.
