In our everyday life, we use different arguments in our discussions to convince others to accept our viewpoint. We do it in the same way in literature i.e. we believe and state what is true and then we gradually build an argument around it to make others believe that what we think is relevant and true. For example, we take a subject as an argument like “Internet is a good invention”. Then, we support it with logical reasons such as “It is a source of information,” and “It is a hub of entertainment,” and so on. In the end, we conclude the argument by giving our verdict.
I hope this will help you out with your question.
