Categories and Classification

Sometimes members of one category will also fit into other categories as well. Here is an example: 


	CATEGORY: Animals
	ITEMS BELONGING TO CATEGORY: rats, snakes, turtles, deer, dogs.

	CATEGORY: Mammals
	ITEMS BELONGING TO CATEGORY: rats, deer, dogs.
As you can see rats, deer, and dogs belong to both the category called animals and the category called mammals.

It is also possible to pick a category for an item. 


  CATEGORIES: tools, furniture, mammals, food.

  Pick the best category for the following item:

	hammer
Of the categories you have to select from, "tools" is the best category for hammer.

Here's another example: 


  CATEGORIES: insects, clothing, sports, desserts.

  Pick the best category for the following item:

	basketball
Clearly a basketball is not an example of an insect, clothing, or a dessert. The best category for basketball is "sports".
