１２、The following appeared in a memo from the owner of Green Thumb Gardening Center, a small business serving a suburban town.

　　There is evidence that consumers are becoming more and more interested in growing their own -vegetables. A national survey conducted last month indicated that many consumers were dissatisfied with the quality of fresh vegetables available in supermarkets. And locally, the gardening magazine Great Gardens has sold out at the Village News stand three months in a row. Thus, we at Green Thumb Gardening Center can increase our profits by greatly expanding the variety of vegetable seeds we stock for gardeners this coming spring.
