Final answer:
In an argumentative essay, authors use facts to support their claim. Option 4 is correct.
Step-by-step explanation:
Facts are verifiable information that can be confirmed through evidence. They are essential in building a strong argument because they provide the foundation for the author's viewpoint. By presenting facts, the author aims to prove their argument and persuade the reader of its validity.
To effectively support a claim, facts are often accompanied by reasoning and evidence in the form of quotations, statistics, expert opinions, and other commonly accepted information. This not only helps to clarify the meaning and significance of the argument but also addresses and refutes counterpoints, thus strengthening the persuasive power of the essay.
When drafting an argumentative essay, it is important to remember that the use of facts should give strength or credibility to your ideas, helping readers to think critically about the topic and understand why your viewpoint is grounded in logic and evidence.
