Final answer:
Labels can be grouped into various types of thinking categories, such as sources of political thought, reasoning strategies, and primary and secondary groups.
Step-by-step explanation:
There are several ways to group the labels according to the types of thinking they describe. One way is to categorize them into three general 'E' groups, which represent sources of political thought. Another way is to organize them based on six widely used reasoning strategies or patterns for thinking and writing, which can help determine the most logical and effective means of organizing information. Additionally, labels can be grouped into primary and secondary groups, which define how we think of ourselves and can be used for comparison or to exclude people.
