8.14 Figure 8.2 shows the top levels of a hierarchy for everything. Extend it to include as many real categories as possible. A good way to do this is to cover all the things in your everyday life.

This includes objects and events. Start with waking up, proceed in an orderly fashion noting everything that you see, touch, do, and think about. For example, a random sampling produces music, news, milk, walking, driving, gas, Soda Hall, carpet, talking, Professor Fateman, chicken curry, tongue, $4, sun, the daily newspaper, and so on.

You should produce both a single hierarchy chart (large sheet of paper) and a listing of objects and categories with one or more relations satisfied by members of each category. Every object should be in a category, and every category should be incorporated in the hierarchy.
