the following appeared in the sherwood times newspaper.

　　"a recent study reported that pet owners have longer, healthier lives on average than do people who own no pets. specifically, dog owners tend to have a lower incidence of heart disease. in light of these findings, sherwood hospital should form a partnership¹ with sherwood animal shelter to institute an 'adopt-a-dog' program. the program would encourage dog ownership for patients recovering from heart disease, which will help reduce medical costs by reducing the number of these patients needing ongoing² treatment. in addition, the publicity³ about the program will encourage more people to adopt pets from the shelter, which will reduce the risk of heart disease in the general population."

　　the following appeared in an editorial in the garden city gazette.

　　"to address the parking problems in our downtown business district, it has been proposed that the city increase parking capacity by building a four-story parking garage. however, this project would cost more than it would to improve the downtown pedestrian plaza⁴. because the pedestrian plaza is an important attraction that draws people to the downtown area, improvements to it will increase business for downtown merchants. the merchants' higher profits will ultimately produce increased tax revenues for the city. therefore, we should invest in the plaza improvements first and then use the revenues thus generated to pay for the construction of the parking garage."

　　the vice⁵ president for human resources at climpson industries sent the following recommendation to the company's president.

　　"in an effort to improve our employees' productivity, we should implement⁶ electronic monitoring of employees' internet use from their workstations. employees who use the internet from their workstations need to be identified and punished if we are to reduce the number of work hours spent on personal or recreational activities, such as shopping or playing games. by installing software to detect employees' internet use on company computers, we can prevent employees from wasting time, foster a better work ethic⁷ at climpson, and improve our overall profits."

　　the following appeared in a health magazine.

　　"it has long been believed that getting at least eight hours of sleep a night is good for health. but a recent six-year study of adult sleeping habits found that people who reported sleeping eight or more hours a night had a higher rate of certain health problems than did those who reported sleeping seven hours a night. people who reported sleeping five hours a night also had an increased rate of the health problems, but this increase was slight compared to that for people who reported sleeping eight or more hours a night. clearly, people should try to get seven hours of sleep, and they should worry more about getting too much sleep than too little."
