The document discusses two types of questions: subject questions and object questions. Subject questions ask about the subject of a sentence and do not change the word order, while object questions ask about the object and require changing the word order. Examples are provided of subject questions using "who" and "what", and object questions where the word order is changed and ends with "who" or "what". The end of the document provides additional examples of subject and object questions.

1. Most questions are object questions. In other words, they
ask about an object.

However, there are also subject questions. Questions we
ask to find out about the subject. These questions are
asked using 'who' and 'what'.
Example: What happened?. Who is knocking at the door?
