Discuss how well reasoned you find this argument. (来源：英语杂志 http://www.EnglishCN.com)

　　1.The following appeared in a letter to the editor of a Batavia newspaper. 

　　"The department of agriculture in Batavia reports that the number of dairy farms throughout the country is now 25 percent greater than it was 10 years ago. During this same time period, however, the price of milk at the local Excello Food Market has increased from $1.50 to over $3.00 per gallon. To prevent farmers from continuing to receive excessive profits on an apparently increased supply of milk, the Batavia government should begin to regulate retail milk prices. Such regulation is necessary to ensure both lower prices and an adequate supply of milk for consumers." 
              
　　2.The following appeared in a memo from the mayor of the town of West Egg. 

　　"Two years ago, our consultants predicted that West Egg’s landfill, which is used for garbage disposal, would be completely filled within five years. During the past two years, however, town residents have been recycling twice as much aluminum and paper as they did in previous years. Next month the amount of material recycled should further increase, since charges for garbage pickup will double. Furthermore, over ninety percent of the respondents to a recent survey said that they would do more recycling in the future. Because of our residents’ strong commitment to recycling, the available space in our landfill should last for considerably longer than predicted." 
 
　　3.The following appeared in a memo from a vice president of Alta Manufacturing. 

　　"During the past year, Alta Manufacturing had thirty percent more on-the-job accidents than nearby Panoply Industries, where the work shifts are one hour shorter than ours. Experts believe that a significant contributing factor in many on-the-job accidents is fatigue and sleep deprivation among workers. Therefore, to reduce the number of on-the-job accidents at Alta and thereby increase productivity, we should shorten each of our three work shifts by one hour so that our employees will get adequate amounts of sleep."  
 
　　4.The following appeared in a memo from the owner of Green Thumb Gardening Center, a small business serving a suburban town. 

　　"There is evidence that consumers are becoming more and more interested in growing their own -vegetables. A national survey conducted last month indicated that many consumers were dissatisfied with the quality of fresh vegetables available in supermarkets. And locally, the gardening magazine Great Gardens has sold out at the Village News stand three months in a row. Thus, we at Green Thumb Gardening Center can increase our profits by greatly expanding the variety of vegetable seeds we stock for gardeners this coming spring."
