I heard some Russian teachers say in class something like this: "Now your homework. Who wants to answer?" (when they want their students to present to the class some home prepared oral activities (monologues, for example) .
I am interested in the verb "to answer". Can it be used without an object in a sentence like the one above? I know that "Who wants to be the first with their homework?" or other similar phrases could be a better alternative, but I just want to know if the verb to answer can be used in the situation described?
If I were a native speaker of English, I would never shut up.)
