When Hooper visits Brody's home, he brings two bottles of wine. Brody pours himself a large measure, and then gives his wife and Hooper some. If you look at the bottle, firstly it seems rather full for the amount he's just poured, and secondly the level changes from shot to shot. Sometimes it's above the label, sometimes below.
The purpose of an Essay Introduction is to introduce the reader to the subject matter you are writing about and to state the intent of the paper.
Write an introduction that interests the reader and effectively outlines your arguments. Every essay or assignment you write must begin with an introduction. It might be helpful to think of the introduction as an inverted pyramid. In such a pyramid, you begin by presenting a broad introduction to the topic and end by making a more focused point about that topic in your thesis statement. The introduction has three essential parts, each of which serves a particular purpose.
