My English question asked if a topic sentence should be short or long.(true or false)

I don't know how to answer this question. is this question false.

I don't know how that can be answered correctly. As I posted before, it's the content of the sentence, not the number of words, that makes the difference.

To determine if a topic sentence should be short or long, we need to understand the purpose of a topic sentence and consider some general guidelines.

A topic sentence is typically the first sentence of a paragraph and sets the tone and focus for the rest of the paragraph. It should clearly introduce the main idea of the paragraph and provide a strong foundation for the following sentences.

Regarding the length of a topic sentence, there is no strict rule that it should be either short or long. However, it is generally recommended to keep the topic sentence concise and specific, usually consisting of around 10-20 words. This helps to maintain clarity and ensure that the main idea is not diluted by unnecessary information.

So, to answer the question, it is neither "true" nor "false" because the length of a topic sentence can vary depending on the specific context and content of the paragraph. However, it is advisable to keep it relatively short and focused.
