　　1.The following was written as a part of an application for a small business loan by a group of developers in the city of Monroe.

　　"A jazz music club in Monroe would be a tremendously profitable enterprise. Currently, the nearest jazz club is 65 miles away; thus, our proposed club, the C Note, would have the local market all to itself. Plus, jazz is extremely popular in Monroe: over 100,000 people attended Monroe's jazz festival last summer, several well-known jazz musicians live in Monroe, and the highest-rated radio program in Monroe is 'Jazz Nightly,' which airs every weeknight. Finally, a nationwide study indicates that the typical jazz fan spends close to $1,000 per year on jazz entertainment. It is clear that the C Note cannot help but make money."
 
　　2.The following appeared in a letter to the editor of the Clear view newspaper.

　　"In the next mayoral election, residents of Clear view should vote for Ann Green, who is a member of the Good Earth Coalition¹, rather than for Frank Braun, a member of the Clear view town council, because the current members are not protecting our environment. For example, during the past year the number of factories in Clear view has doubled, air pollution levels have increased, and the local hospital has treated 25 percent more patients with respiratory illnesses. If we elect Ann Green, the environmental problems in Clear view will certainly be solved."

 
　　3.The following appeared in a memorandum² issued by the strategic planning department at Omni Inc.

　　"Mesa Foods, a manufacturer of snack foods that currently markets its products within a relatively³ small region of the country, has strong growth potential. Mesa enjoyed a 20 percent increase in profits last year, and its best-selling product, Diabolique Salsa, has had increased sales over each of the past three years. Since Omni Inc. is interested in reaching 14-to-25 year olds, the age group that consumes the most snack food, we should buy Mesa Foods, and concentrate in particular on marketing⁴ Diabolique Salsa throughout the country."
 
　　4.The following appeared in a memorandum from a dean at Omega University.

　　"Fifteen years ago, Omega University implemented⁵ a new procedure that encouraged students to evaluate the teaching effectiveness of all their professors. Since that time, Omega professors have begun to assign higher grades in their classes, and overall student grade averages at Omega have risen by thirty percent. Potential employers apparently⁶ believe the grades at Omega are inflated⁷; this would explain why Omega graduates have not been as successful at getting jobs as have graduates from nearby Alpha University. To enable its graduates to secure better jobs, Omega University should now terminate student evaluation⁸ of professors."
