This document discusses subject and object questions in sentences. Transitive verbs require both a subject and an object. In object questions, the subject is known but the object is unknown, so the question word comes before the auxiliary verb. In subject questions, the object is known but the subject is unknown, so the verb comes directly after the question word. Examples are provided of object questions like "What does Mark watch?" and subject questions like "Who watches films?".
