Here's why:
* Interrogative sentences ask questions. They typically begin with question words like "who," "what," "where," "when," "why," or "how." They also often use an inverted word order (e.g., "Do you like pizza?").
* Declarative sentences make statements. They state a fact or opinion.
To turn the phrase into an interrogative sentence, you could ask:
* Do you do your homework last?
* When do you do your homework?
