RLA Main Idea and Details 4 — Questions and Answers
Question 1: Which of the following BEST describes the difference between a topic and a main idea?

- A topic names the subject; a main idea states the author's point about that subject. (Correct answer)
- A topic is always in the first paragraph; a main idea is always at the end.
- A topic includes details; a main idea does not.
Correct answer: A topic names the subject; a main idea states the author's point about that subject.
The topic identifies what the passage is about, while the main idea expresses the author's central claim or message about that topic.
Question 2: Read: 'Despite facing rejection from multiple publishers, J.K. Rowling persisted until Harry Potter was accepted. Today the series has sold over 500 million copies.' What is the implied main idea?

- Persistence in the face of rejection can lead to great success. (Correct answer)
- Fantasy novels are the most popular book genre worldwide.
- Harry Potter is the best-selling book series of all time.
Correct answer: Persistence in the face of rejection can lead to great success.
The contrast between early rejection and massive eventual success implies that persisting through failure leads to achievement.
Question 3: A detail that gives a specific example, statistic, or explanation is best described as:
- A main idea
- A thesis
- A supporting detail (Correct answer)
- A topic sentence of the whole passage
Correct answer: A supporting detail
Specific examples, statistics, and explanations serve as supporting details that back up the main idea.
Question 4: A passage has five paragraphs. Paragraphs 2–5 each describe a different challenge faced by small business owners. Paragraph 1 most likely contains:
- A counterargument against small businesses
- The main idea about challenges facing small business owners (Correct answer)
