This document discusses direct and indirect questions. Direct questions are normal questions asked to people you know well, while indirect questions are more formal and polite for situations where you don't know the person as well, such as professionally. Indirect questions use phrases like "Could you tell me" or "Do you know" and change the structure and verbs used compared to direct questions, such as using "moved" instead of "move" and placing forms of "be" and "have" after the subject. The document provides examples of direct questions and their indirect equivalents to illustrate these rules.
