A1. The following editorial appeared in the South Fork Gazette.
“Last year, the city contracted with Flower Power to plant a variety of flowers in big decorative pots on Main Street and to water them each week. By midsummer many of the plants were wilted. This year the city should either contract for two waterings a week or save money by planting artificial flowers in the pots. According to Flower Power, the initial cost for artificial flowers would be twice as much as for real plants, but after two years, we would save money. Public reaction certainly supports this position: in a recent survey, over 1,200 Gazette readers said that the city wastes money and should find ways to reduce spending.”

In this argument, the author indicates that it is cost-effective to replace real flowers by artificial flowers. To support his conclusion, the author points out that those real flowers need more water to survive in mid-summer. In addition, he reasons that even though the use of artificial flowers spends twice the amount of money of the maintenance of real flowers initially, people will be beneficial to this alternative in a long run. Moreover, a recent survey quoted is cited citizens’ dissatisfaction with the fiscal performance and their hope of reduction of public spending. As I analyze this argument in close concert, the author’s view is not very convincing for three major reasons.
 
In the first place, the evidence the author provides is insufficient to support that the use of artificial flowers can reduce public spending, even in a long run. The author may emphasize the merit of artificial flowers that they never need water to survive or grow. But he fails to notice that over time, the outside artificial flowers inevitably become messy and dirty, weakening their decorative function. Then people also have to wash them with considerable amount of water. Furthermore, the sun fades the color of artificial flowers. Hence, the city need spend a supplementary cost to replace old ones.
 
In the second place, the author distorts the readers’ ideas about ways to reduce public spending. Readers never specify that an end to the use of real flowers should be one way to reduce public expense. Readers may call for changes in other public work and services other than the replacement of real flowers. As far as I know, lots of people have inherent preferences for real flowers, due to their peculiar features. When real flowers are blossoming, fragrant smell spreads over a large area. Compared with artificial flowers, real flowers can change their appearance at all seasons.
 
In the third place, the survey quoted by the author is worthless because some of its details have not been provided. Without additional information, such as the total number of people in the city or the framework of who were conducted, the result of the survey may lack representative. We can picture that the city has a population of more than 5 million, but this survey conducted only 1200 people, especially readers who are easily affected by the gazette’s editorial.
 
Since the author commits logical mistakes mentioned above and fails to consider the whole situation comprehensively, his ideas should not be adopted. The conclusion would be strengthened if he can obviate these three major logical msitakes.
