Question

Imagine that you plan to write a procedural document. What question should you ask yourself to ensure that you address your audience correctly?
A. Do I know anyone who has a lot of experience with this topic?
B. What research should I do in order to understand my topic better?
C. What type of style — formal or informal — will my readers best respond to?
D. What type of media should I use to illustrate my topic?

Answer 1

The answer is c, the style in which a reader will best respond to, formal or informal. 

Answer 2

C. What type of style — formal or informal — will my readers best respond to?

This is the most specific audience-involved question that you should ask yourself. Understanding your audience and they style that they are going to respond to the best will make it easier for you to reach them and get them to understand what you're saying.
