Which is the appropriate way to brainstorm ideas? a. list all of your ideas in alphabetical order. b. cross out bad ideas as you go. c. find ways in which the ideas relate. d. think of your own ideas individually, and then share them.

Brainstorming is a way to think about ideas, not worrying about editing whatsoever. It's a process of identifying ideas or a topic upon which you want to focus on, possibly solutions as well. If you are brainstorming in a group situation, you should think aloud and say whatever comes to mind. Therefore, the appropriate way to brainstorm ideas is to relate your thoughts with others in the group to come up with an agreed upon solution/topic. Brainstorming is often considered a process of association, meaning relation from one idea to another. 

C. Find ways in which the ideas relate.
