What's expository?

Expository writing is a type of writing, where it is used to inform people using logic, credibility, ethics and emotions.(Logos, Ethos and Pathos) It maybe used to persuade or argue against someone. Most of the time, we can see them in commentaries or discussions in newspaper, debates or comments. Expository is rather useful to counter a point and even gain good points from ethically bad points in the case of Thank You for Smoking, a movie which argues for cigarette which, to most of the non-smokers, are bad as they are harmful and increases chances of cancer. The character, Nick Taylor, argues for cigarette even though he knows the harmful effects of cigarette on human body.
