Discuss how well reasoned you find this argument.

　　1.The following is from an editorial in the Midvale Observer, a local newspaper.

　　"Ever since the 1950's, when television sets began to appear in the average home, the rate of crimes committed by teenagers in the country of Alta has steadily¹ increased. This increase in teenage crime parallels the increase in violence shown on television. According to several national studies, even very young children who watch a great number of television shows featuring violent scenes display more violent behavior within their home environment than do children who do not watch violent shows. Furthermore, in a survey conducted by the Observer, over 90 percent of the respondents were parents who indicated that prime-time television--programs that are shown between 7 p.m. and 9 p.m.---should show less violence. Therefore, in order to lower the rate of teenage crime in Alta, television viewers should demand that television programmers reduce the amount of violence shown during prime time."
 
　　2.The following appeared in the editorial section of a health and fitness magazine.

　　"In a study of the effects of exercise on longevity², medical researchers tracked 500 middle-aged³ men over a 20-year period. The subjects represented a variety of occupations in several different parts of the country and responded to an annual survey in which they were asked: How often and how strenuously⁴ do you exercise? Of those who responded, the men who reported that they engaged in vigorous outdoor exercise nearly every day lived longer than the men who reported that they exercised mildly only once or twice a week. Given the clear link that this study establishes between longevity and exercise, doctors should not recommend moderate exercise to their patients but should instead encourage vigorous outdoor exercise on a daily basis."
 
　　3.The following appeared in a letter to the editor of a local newspaper.

　　"Too much emphasis is placed on the development of reading skills in elementary school. Many students who are discouraged by the lonely activity of reading turn away from schoolwork merely because they are poor readers. But books recorded on audiocassette tape provide an important alternative for students at this crucial stage in their education, one the school board should not reject merely because of the expense involved. After all, many studies attest⁵ to the value of allowing students to hear books read aloud; there is even evidence that students whose parents read to them are even more likely to become able readers. Thus, hearing books on tape can only make students more eager to read and to learn. Therefore, the school board should encourage schools to buy books on tape and to use them in elementary education."
 
　　4.The following is taken from an advertisement placed in a weekly business magazine by the Dickens Academy.

　　"We distributed a survey to senior management at International Mega-Publishing, Inc. The result of the survey clearly indicates that many employees were well prepared in business knowledge and computer skills, but lacked interpersonal skills to interact gracefully⁶ with customers. International Mega-Publishing decided⁷ to improve customer satisfaction by sending their newly hired employees to our one-day seminars. Since taking advantage of our program, International Mega-Publishing has seen a sharp increase in sales, an indication that the number of their disgruntled customers has declined significantly. Your company should hire Dickens and let us turn every employee into an ambassador for your company."
