Here are some possible interpretations and questions you might be trying to ask:
* "What did the typist do?" This is asking for an action the typist performed. For example, "What did the typist type?" or "What did the typist do after the meeting?"
* "How did the typist [do something]?" This asks for the method or process the typist used. For example, "How did the typist type so quickly?" or "How did the typist manage to finish all the reports on time?"
* "Did the typist [something]?" This is a yes/no question about whether the typist performed a specific action. For example, "Did the typist make a mistake?" or "Did the typist save the document?"
Please provide more information about what you're looking for. For example, you could say:
* "What did the typist type?"
* "How did the typist learn to type so fast?"
* "Did the typist proofread the document before sending it?"
Once you give me more context, I can provide a more accurate and helpful response.
