Final answer:
Circular reasoning occurs in arguments when the premises assume the conclusion's truth, as exemplified by stating a book is well-written because its author is a good novelist without providing separate evidence.
Step-by-step explanation:
Circular reasoning occurs in an argument when the premises suppose the truth of the conclusion instead of supporting it. For instance, saying that 'The Hate U Give is a well-written book because Angie Thomas is a good novelist' is an example of circular reasoning because the quality of being a good novelist is assumed as the reason for the book being well-written without providing any separate evidence to support this claim.
The problem with circular arguments is that they do not prove anything beyond what is already assumed - they simply restate the conclusion in a different form. This kind of reasoning is problematic because it does not provide any new information or justification to persuade someone of the conclusion's validity.
