How do I write a argumentive essay on "Big Black Good Man" by Richard Wright?I have read the short story, but I don't understand what I am suppose...

"Argue" is part of the vernacular of academic language
that it sometimes takes a little time for students to understand. Think of "argue" in
terms of an academic conversation that occurs on paper. It works like this: You have an
Idea about something you read, perhaps you think the big black man, Jim by name, turns
at the end and says, "Daddy-O, drop dead" to Jensen because it broke Jim's heart to find
out that all this time Jenson was afraid of him and feeling like his life was in danger.
In the academic conversation that occurs on paper, you want to express your Idea,
because you are excited about it, and you want to prove that your Idea is correct by
mentioning the quotes or symbolism etc. from the story that made you think of your Idea.
This process is called "arguing": It is presenting an Idea you have that you "prove" by
"arguing" its truthfulness, correctness and/or importance by pointing out words, lines,
passages, concepts, and ideas in the story that indicate--or "support"--your
Idea.

You'll start your academic conversation, or argument,
with an Introduction that tells the people you're "conversing" with the Who or What
you're talking about ("Big Black Good Man," a 1958 short story by Richard Wright; the
character named Jim), the When and Where of what you're talking about (August 1958,
Denmark, Copenhagen), and the Why of your reason/purpose/aim in writing about your Idea
(e.g., "to illuminate a psychological aspect of the story"), and the How of the paper
conversation you're writing, which for literary papers may often be an analysis or a
comparative essay (e.g., "an analysis of the text shows that..."). Finally your
Introduction will contain the statement of your Idea, which in academic terminology is
called your Thesis Statement, which is short for Hypothesis Statement, a concept you are
probably already familiar with from science classes.

Your
paper academic conversation--called your argumentative essay--will present at least
three (three is a generally recommended number) well chosen quotes, discussions of
symbolism, discussion of vocabulary, or any other literary device that makes it clear
that your Idea is a sound one that comes from what you read in the story and that other
people can also find in the story after reading your contribution to the academic
conversation--which of course is your argumentative
essay.

You'll follow this with a Conclusion that reflects
back at what you have done to establish the truth etc. of your Idea and then suggests
what other research might be interesting in terms of adding more understanding to the
topic (e.g., Jim) that you're discussing. Once you've done these things, you have
"argued" your point in the essay that is your contribution to the ongoing academic
conversation about "Big Black Good Man" or whatever other work of literature you discuss
in future.
