The fact "If you want to eat vegetables then you should buy some vegetables and wash them." is illustrated with the story:1. I wanted to eat some zucchini with my pasta.2. I went to the store and bought some zucchini.3. I took the zucchini home and washed it in the sink to remove dirt, bacteria and pesticides.4. I chopped up the zucchini and put it in a pot of boiling water with some pasta shells.5. When the zucchini and the pasta were soft, I took them out, added some sauce, mixed it all together, and ate it.
