A Draft of a Student Essay

The statement that provides the best introduction for the passage is:

C. As a boy, Georg was fascinated by the culture of Egypt, and even though it was not a popular subject to pursue, he devoted many years to learning as much as he could about it.

Explanation:

The best introduction to the passage contains the main idea or topic.  In this case, the main topic is "the culture of Egypt."  This is followed by a proposal made by the writer which outlines her opinion or claim (thesis).  The introduction statement above also shows the writer's claim, "the culture of Egypt was not a popular subject to pursue."  Lastly, the best introduction after stating the main topic and the writer's thesis, must be followed by some supporting arguments.  These are statements D, B, and A in that sequential order.

Therefore, I will re-arrange the passage as follows, to show that C statement is the best introduction and that other statements sequentially support it.  I have also bolded the linkages in the arguments to prove that the sequence is in order.
