　　1.A recent sales study indicated that consumption of seafood dishes in Bay City restaurants has increased by 30 percent over the past five years.

　　Yet there are no currently operating city restaurants that specialize in seafood. Moreover, the majority of families in Bay City are two-income families, and a nationwide study has shown that such families eat significantly fewer home-cooked meals than they did a decade ago but at the same time express more concern about eating healthily. Therefore, a new Bay City restaurant specializing in seafood will be quite popular and profitable.
　　
　　2.The following appeared in a memo from the president of Viva-Tech, a manufacturer of high-tech medical equipment.

　　"In order to reduce costs, we should close some of our existing small assembly plants and build a large central plant. Grandview would be an ideal location for this new plant. First, of the locations that we have considered, Grandview has the largest adult population, so that we will be able to staff our plant quickly and easily. Second, since the average wage earned by workers in Grandview is less than that in the other locations, we should be able to keep production costs low. Last, as an inducement for us to build there, Grandview's town council has offered to allow us to operate for the first three years without paying city taxes."
 
　　3.The following appeared in a memo from the mayor of the town of Hopewell.

　　"Two years ago, the town of Ocean View built a new municipal golf course and resort hotel. During the past two years, tourism in Ocean View has increased, new businesses have opened there, and Ocean View's tax revenues have risen by 30 percent. The best way to improve Hopewell's economy, and generate additional tax revenues, is to build a golf course and resort hotel similar to those in Ocean View."
 
　　4.The following appeared in a memo from the chairperson of the school board in the town of Saluda.

　　"For the past five years, Mr. Charles Schade has been the music director at Steel City High School, and during that time the school band from Steel City High has won three regional band competitions. In addition, the quality of the music rehearsal facilities and musical instruments at Steel City High has improved markedly over the past five years. Because of such successes at Steel City High, the Saluda school board should hire Mr. Schade to plan and direct the general music education programs for the entire Saluda school system."
