It should be reliable and sufficient. Facts speak louder than words and are the best argument. Arguments can also be accepted truths. ?

1, argument (something to prove). It is a sentence that correctly and clearly expounds the author's point of view, and it is the soul and command of an article. Any article has only one central argument, and generally there can be sub-arguments. ?

2. demonstrate (prove what). It is the material to support the argument and the reason and basis used by the author to prove the argument, which can be divided into factual arguments and theoretical arguments.

3. Demonstration (how to prove it). It is the process of proving an argument with rigorous arguments. The purpose of argument is to reveal the internal logical relationship between arguments. ?
