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.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
