Position statement:
Tell the reader the position you will take in relation to the question.
You can precede this with a general opening statement about the topic
but this is optional.
Preview of arguments:
Give the reader an idea of how your argument will be structured.
For example, outline the main points of your argument in the order
in which they will be presented.
If there are any ambiguous or controversial words or phrases in the
topic, define or clarify them here. If you have a lot to say about
the meaning of a word, then you should do so as a separate point in
the body of the essay.
