AA：124. The following appeared in a memorandum from the owner of Carlo’s Clothing to the staff.
“Since Disc Depot, the music store on the next block, began a new radio advertising campaign last year, its business has grown dramatically, as evidenced by the large increase in foot traffic into the store. While the Disc Depot’s owners have apparently become wealthy enough to retire, profits at Carlo’s Clothing have remained stagnant for the past three years. In order to boost our sales and profits, we should therefore switch from newspaper advertising to frequent radio advertisements like those for Disc Depot.”

AI: 65. “The rise of multinational corporations is leading to global homogeneity*. Because people everywhere are beginning to want the same products and services, regional differences are rapidly disappearing.”
