A、Because the bean is an important food in areas of Asia. B、Because it has different flavor. C、Because the appearance is special

Farmers might think the idea of (26) growing food for fun sounds strange. But there are some people who do it all the time. They grow some vegetables because their natural color or shape is pleasing to see. They grow others because scientists have developed new colors or different sizes for traditional vegetables. One example is the bell pepper. Seed companies sell seeds for several different kinds of bell peppers. One pepper is a weak yellow color when it begins to grow. Then its color changes to white. As it grows, it changes color two more times--to orange, then red. If you are not interested in peppers that change colors as they grow, you can grow some that remain one color. You can try chocolate-colored peppers. Or purple. Or lavender ones. Each kind of pepper has its own special taste. (27) For the best possible taste, however, peppers should be left on the vine for two or three weeks after they appear ready. This gives them full flavor and greatly increases the vitamins they contain. Another unusual plant is known as the yard-long bean, or snake bean. It grows up to one meter in length. It is an important part of the food supply in areas of Asia. (28) American farmers like it because it is different, yet tastes very much like the green beans they traditionally grow. Each bean has from ten to twenty seeds. The outside can be eaten. Some of the very long beans are green outside but have black-and-whit6 or red seeds.
