Questions1 to 5 are based on the following passage. Vegetable gardening is the relaxing art and science of turning a love for growing plants into a productive activity. Many things make it a national hobby for both the young and old. For a large number of people, seed catalogs and the thoughts of spring gardening will provide a happy escape from winter boredom. Vegetable gardeners agree that many home-grown vegetables picked at their best are superior to those vegetables purchased from markets. From spring through late fall, a well-planned and well-kept garden can provide a supply of fresh vegetables, thus increasing the nutrition in the family diet. Freezers make it possible to keep some of the vegetables to be enjoyed at a later date. Other vegetables can be stored for a few months in a cool area. Having vegetables in the backyard makes home gardening appealing for many people. In addition, vegetable gardening provides exercise and fun for both urban and suburban families. Although the money spent for a garden may be little, one cannot escape the fact that gardening requires hard work and time. Many of the gardening tasks must be performed at times that are most inconvenient. Not doing jobs that should be done on a regular basis may result in failure and a negative feeling toward gardening. One should not plant a garden that is too large to care for. A small well-kept garden is more enjoyable and profitable than a large neglected one.

If possible, the garden should be near the house so the gardener can work in it at odd moments. Why do many people like vegetable gardening?
