Why do writers provide evidence to support the big ideas they wish to convey to audiences? to show that many previous writers have thought about the same ideas in the past to prove that the writers are not plagiarizing—not stealing other people's words to demonstrate that the ideas aren't just the author's opinion but are factually convincing to offer readers the chance to present counterarguments or alternative arguments

The correct answer is C. To demonstrate that the ideas aren't just the author's opinion but are factually convincing

Explanation:

In texts, it is common writers support ideas using evidence; for example, they quote articles, books or scientific studies. This shows the ideas of the author have been proven by others, and therefore the text is based on facts rather than only opinions. For example, if you want to convince the audience exercise is good for health, you need to demonstrate this through evidence such as medical research. Thus, writers provide evidence to demonstrate that the ideas aren't just the author's opinion but are factually convincing.
