·Read the following passage and choose the best word for each space.
Money spent on advertising is money spent as well as any (26) know of. It serves directly to assist a rapid of goods at reasonable prices, (27) establishing a firm home market and so making it possible to provide (28) export at competitive prices. By drawing attention to new ideas it helps enormously to raise standards of living. By helping to increase demand it (29) an increasing need for labor, and is therefore an effective way to fight unemployment.

If its message were (42) merely to information—and that in itself (43) difficult if not impossible to achieve, (44) even a detail such as the choice of the color of a shirt is subtly persuasive — advertising would be so boring (45) no one would pay any attention. But perhaps that is what the well-known television personality wants.
