　　1.The following appeared in a letter from a department chairperson to the president of Pierce University.

　　"Some studies conducted by Bronston College, which is also located in a small town, reveal that both male and female professors are happier living in small towns when their spouses² are also employed in the same geographic³ area. Therefore, in the interest of attracting the most gifted teachers and researchers to our faculty⁴ and improving the morale⁵ of our entire staff, we at Pierce University should offer employment to the spouse¹ of each new faculty member we hire. Although we cannot expect all offers to be accepted or to be viewed as an ideal job offer, the money invested in this effort will clearly be well spent because, if their spouses have a chance of employment, new professors will be more likely to accept our offers."
 
　　2.For the past five years, consumers in California have been willing to pay twice as much for oysters⁷ from the northeastern Atlantic Coast as for Gulf⁸ Coast oysters. This trend began shortly after harmful bacteria were found in a few raw Gulf Coast oysters. But scientists have now devised a process for killing⁹ the bacteria. Once consumers are made aware of the increased safety of Gulf Coast oysters, they are likely to be willing to pay as much for Gulf Coast as for northeastern Atlantic Coast oysters, and greater profits for Gulf Coast oyster⁶ producers will follow.
 
　　3.The following appeared in a memo¹⁰ from the marketing¹¹ director of "Bargain Brand" Cereals.

　　One year ago we introduced our first product, "Bargain Brand" breakfast cereal. Our very low prices quickly drew many customers away from the top-selling cereal companies. Although the companies producing the top brands have since tried to compete with us by lowering their prices, and although several plan to introduce their own budget brands, not once have we needed to raise our prices to continue making a profit. Given our success selling cereal, Bargain Brand should now expand its business and begin marketing other low-priced food products as quickly as possible.
 
　　4.The Mozart School of Music should obviously be the first choice of any music student aware of its reputation. First of all, the Mozart School stresses intensive practice and training, so that students typically begin their training at a very young age. Second, the school has ample facilities and up-to-date professional equipment, and its faculty includes some of the most distinguished¹² music teachers in the world. Finally, many Mozart graduates have gone on to be the best known and most highly paid musicians in the nation.
