1. True
2. False

Please recheck my answer.

The CONTENT of a topic sentence is far more important than how many words are in it!!

Just a question

Can a topic sentence be short?

How short is short?

Short or long -- it makes no difference. It's the CONTENT that matters. It is where you state the MAIN IDEA for the paragraph.

Actually, the correct answer is False. A topic sentence should be concise and to the point, usually consisting of about 10-15 words. It should provide a clear and specific overview of the main idea or focus of a paragraph or section of writing. The purpose of a topic sentence is to introduce the main point and guide the reader through the rest of the paragraph or text. Therefore, it is important to keep the topic sentence concise and easy to understand.
