１１５、The following appeared in a memo from the sales manager of Eco-Power, a company that manufactures tools and home appliances. "Many popular radio and television commercials use memorable tunes and song lyrics to call attention to the products being advertised. Indeed, a recent study of high school students showed that 85 percent could easily recognize the tunes used to advertise leading soft drinks and fast-food restaurants. Despite our company’s extensive advertising in magazines during the past year, sales of our home appliances declined. Therefore, to boost company profits, we should now switch to advertisements featuring a distinctive song."
