AAA30集思广益中参加讨论提高自己惠及他人

A30. The following appeared in a memorandum from the president of Didactica, a company that publishes textbooks.
“We have just taken an important step toward promoting our textbooks more effectively. Didactica has signed a contract with MousePrints, Inc., a company that supplies advertising-sponsored mousepads to schools free of charge. Each mousepad is printed with four ageappropriate, education-related ads that include Web site addresses, and since the mousepads are placed next to computers in classrooms and computer labs, the users of the computers are likely to visit Didactica’s Website. This method of familiarizing students and teachers with our company will help us increase our sales revenues and our share of the textbook market.”

1There is no evidence to support the author's assumption that teachers and students are likely to visit Didactica's websites simply because they have immediate access to the address.
2Even if they are likely to visit the website, there is no guarantee that they will buy more textbooks published by the Didactica.
3The author's assertion is based on the assumption that its competitors will not do the same kind of promotion.
