TOPIC: ARGUMENT20 - The following appeared in a letter to the editor of the Balmer Island Gazette.
"The population of Balmer Island increases to 100,000 duing the summer months. To reduce the number of accidents involving mopeds and pedestrians, the town council of Balmer Island should limit the number of mopeds rented by each of the island's six moped and bicycle rental companies from 50 per day to 30 per day during the summer season. By limiting the number of rentals, the town council is sure to attain the 50 percent reduction in moped accidents that was achieved last year in the neighboring island of Torseau, when Torseau's town council enforced similar limits on moped rentals."
WORDS: 510
In order to decrease the number of accidents between mopeds and pedestrians, the author argue that the Balmer Island's council should adopt the similar measure, limiting the number of moped rentals. Considering the supporting evidence of this argument, I believe that it rests on a series of unsubstantiated assumptions and is therefore unpersuasive as it stands.
Before discussing the validity of limiting the number of rental mopeds in Balmer Island, we should judge the necessity of paying more our attentions to the accident including mopeds and pedestrians than others such as car accidents. The premise of this argument is that the proportion of moped accidents accounts for a greater percentage of accidents happening in Balmer Island. But there is not any evidence to provide the percentage of moped accidents in this region. In our common sense, car accidents are more regular in contemporary society and the result of them are more serious than moped accidents. Based on this unreliable premise, the arguer may conclude a false assertion.
Even though assuming the reduction of moped accidents is necessary, the arguer could not regard the limitation of rental mopeds as an efficacious resolution of such accidents. The author assumes that Torseau Island succeed in tackling with the problem of moped accidents in last year. Reducing fifty percent of moped accidents can not lend a strong support to prove the success of this limitation, because if the number of such accidents is huge. So this reduction may not completely solve the problem. Taking this factor into account, we could not expect the limitation will make sense in Balmer Island as well as island of Torseau. Even though assuming the limitation would really resolve the moped accident in Torseau Island, the author may ignore the difference between island of Balmer and island of Torseau. Such distinctions may include the factor that there are less rental mopeds but more private mopeds in Balmer Island. It is possible that there are more moped rentals in Torseau Island. Therefore, the similar limitation of rental mopeds may not effect both islands in the same way.
Finally, assuming Balmer Island could take the limitation to diminish the moped accident, the arguer may not suggest its government to limit the number of moped rentals, in each six moped and bicycle rental companies, from fifty to thirty. The arguer assumes that the number of rental mopeds in six companies is more than thirty. But it is possible that this number may be less than thirty, so the limitation is no use at all. Without ruling out the factor mentioned above, the arguer should not put out his advice depending on his own assumption.
To sum up, the reasoning behind reducing the number of moped rentals back to its original seems logical as presented in the argument, because the author just wants to protect the safety of Balmer Island and its interest. However, if have included the analysis of accidents in this place and the detail and result of Torseau Island's limitation, the argument would have been more thoroughly and logically acceptable.
