how do nonfiction authors strengthen their arguments?\na. by providing evidence\nb. by using fiction elements\nc. by avoiding details\nd. by using slang
Answer
Brief Explanations:
Non - fiction writing is based on facts. Providing evidence (such as data, expert quotes, real - life examples) helps to support and strengthen the author's arguments. Using fiction elements (which are for made - up stories) is not relevant for non - fiction argument strengthening. Avoiding details would weaken an argument as there is less support. Using slang is more about style and not about strengthening an argument in a formal non - fiction context.
Answer:
A. By providing evidence
