Answer:
Brainstorming
Step-by-step explanation:
Brainstorming is considered to be the necessary first step to take when you are planning a writing project. Brainstorming occurs when you try to come up with all the things you know or have heard about a particular topic. This is a preliminary step, because many of the ideas that you will mention will not be useful for your writing. However, eventually, some might be, and the brainstorming process helps you separate the two.
