This document discusses two types of questions - direct and indirect questions. Direct questions use helping verbs like "is", "are", "do" and can be answered with "yes" or "no". Indirect questions start with wh- words like what, when, where and use helping verbs with the subject and main verb. The document provides examples of direct questions with "to be" verbs, direct questions with other verbs using "do/does", and indirect questions starting with wh- words and using helping verbs.
