Once your readers believe in your characters, you must get them to care. Each reader must be able to identify with at least one character, to almost become that character in his or her mind. You can do this by developing characters with genuine human traits, both good and bad. The individuals who populate your story should have human strengths and weaknesses.
Now it’s time to weave your tale, to create a plot. Your readers are part of the story now; they are involved.
One last thing. Your story must touch the readers’ emotions. If you can make them laugh and cry along with your characters, you will be a successful writer.

What would
A. To write about their virtue and vice.
B. To describe their emotions.
C. To include their laughter and cries.
D. To identify with them.
