Answer:
True
Step-by-step explanation:
The article's topic must relate to the main idea in a piece. All three words, main idea, purpose, and topic are synonyms. The main idea is the topic, central, or most important, idea in a paragraph or passage. It states the purpose and sets the direction of the paragraph or passage.
For example, if a you write a narrative story that talks about you walking in the park, you would obviously name it something like a stroll in the park, and not something super off topic like Recent basketball games.
Hope this helps :)
