Question

4. Which one of the following statements about a topic sentence and a main idea is accurate? A. A topic sentence and a main idea are always the same thing. B. A topic sentence is the central idea of a paragraph, while a main idea is the central idea of an entire text. C. A topic sentence is found in the introduction, while a main idea is found in the conclusion. D. A topic sentence does not change position, but the main idea can be found in multiple places.

Answer 1

It is most likely B although C could also be a good option but the main idea is spread through-out the paper and a topic sentence introduces what the current paragraph would be talking about. 

Answer 2

I believe the correct answer is "B. A topic sentence is the central idea of a paragraph, while a main idea is the central idea of an entire text."

A main idea is usually the thesis of the writing piece that addresses the question/prompt and branches over everything that you write. The topic sentences usually branch off of the main idea or thesis and indicate the topics you are discussing in each individual paragraph/section.
