Read the following passage from G. K. Chesterton's "The Philosophy of the Schoolroom" and answer the question. (1) What modern people want to be made to understand is simply that all argument begins with an assumption; that is, with something that you do not doubt. (2) You can, of course, if you like, doubt the assumption at the beginning of your argument, but in that case you are beginning a different argument with another assumption at the beginning of it. (3) Every argument begins with an infallible dogma, and that infallible dogma can only be disputed by falling back on some other infallible dogma; you can never prove your first statement or it would not be your first. (4) All this is the alphabet of thinking. (5) And it has this special and positive point about it that it can be taught in a school, like the other alphabet. (6) Not to start an argument without stating your postulates could be taught in philosophy as it is taught in Euclid, in a common schoolroom with a blackboard. (7) And I think it might be taught in some simple and rational degree even to the young, before they go out into the streets and are delivered over entirely to the logic and philosophy of the Daily Mail.

Which of the following sentences, if placed before sentence 1, would best orient the audience and provide an engaging introduction to the topic of the paragraph?

A) All students of discourse and debate need to learn how to argue effectively; they should practice regularly to hone their craft.

B) Argumentation is so abundant in the modern era that we ought to teach even the youngest children about dogma and postulates.

C) Those who study the art of argumentation and debate understand one simple fact: dogma is the enemy of an effective line of reasoning.

D) With arguments bombarding us almost constantly, it is imperative that we understand argumentation and how it works.
