Answer:
The way characters are described
The situations in which the characters interact
Dialogue between characters
Conflicts within and between characters
Explanation:
Characters are first developed by how they are described. They are not going to throw a character with no description into a book. They will say, a skinny, lanky kid named George was frighted by the dark. This character is fearful of the dark and he may not be that strong for a skinny, lanky kid. Situations where they interact are important because of how they react and respond to another person. For example, Samantha liked Steven so she acted shyly, but confident around him. When she interacts with Steven, it shows that she is not scared or choked up, but confident and shy with him. Dialogue is important because of what they say and how they say it. For example, I asked Duke a question and he snarled at me, "figure it out yourself." This shows that Duke is not the best to talk to at the moment, so he must be easily agitated. Conflicts are important because it shows how they were before, during, and how they became after. It shows the before and after of their character, for example, George was afraid of the dark, but then as he got a flashlight, he was able to use it if he thought something was there. After using it numerous times, he realized nothing was there and he did not need it anymore. You him when he was scared, helped with, and then not scared.

It is important to know the author's purpose because knowing the author's purpose can change how the story is being told.

If the author's purpose was to persuade, that person would be persuading the mom to get him the video game.
