Child moved out after college and got married.

My son lived with me until late July (he was a college student). At the point he moved out and got his own place. He got married in September. I'm answering the questions in order did he get married, and then will he file a return, and then it asked "Did [your son] file this return just to get a refund of withheld tax?"  That question doesn't make sense. He's filing taxes because it's required by law. Of course, he's hoping to get a tax refund, but that's not what the question asks. So how do I answer this?
