This document provides a summary of wh- questions and their functions: 1) Wh- questions ask for specific information that cannot be answered with a simple yes or no. They include who, what, where, when, why, and how. 2) Questions using "who" ask about people, "what" asks about things, "where" asks about places, and "why" asks for a reason. 3) Contractions are often used in wh- questions in informal speech, such as "Where's" instead of "Where is." Answers to wh- questions are usually short but can also be longer explanations.
