An example of an introduction

Before I begin to answer your question, perhaps I should make a few remarks about asking questions. Questions should be full sentences. "An example of an introduction" is not a full sentence. I am assuming that your question is "What is an example of an intoduction?", although it could be "How do you write an example of an introduction?", or "Is Paradise Lost an example of an introduction?"

Now, to answer your question, or what I presume to be your question. What is an example of an introduction? That was.
