when writing an argumentative essay, what is the most important reason authors conduct research?\no to find statements that express their opinion\no to find evidence to support their arguments\no to find statements of other peoples opinions\no to find long quotations to include in the essay
Answer
Brief Explanations:
In an argumentative essay, the core is to persuade the reader. Strong evidence from research bolsters the author's arguments, making them more credible. While finding statements (own or others') and quotations can be part of the process, their ultimate aim is to support the arguments. So, the key is evidence for arguments.
Answer:
to find evidence to support their arguments
