To correctly form the question "When did Mag finish school?", we need to follow a few steps. Let's break it down:
- Identify the subject: In this case, the subject is "Mag".
- Identify the verb: The verb here is "finish". Since we are referring to a completed action in the past, we need to use the past tense of the verb.
- Use the correct auxiliary verb: For forming questions in the past tense, we use "did". This is important because "did" helps us to structure the question correctly.
- Formulate the question: The correct structure for a past tense question is: "When + did + subject + base form of the verb?". So, we replace "subject" with "Mag" and "base form of the verb" with "finish".
Putting it all together, we get:
When did Mag finish school?
This structure helps you ask about a specific time in the past when an event occurred. Remember, using "did" indicates that we are talking about something that has already happened.
