Transform the source sentence 'The repair took three hours.' into a duration question. Use how long. Rewrite the exact fragment 'three hours' and use the verb take in the complete question: ___
Respuesta correcta
- How long did the repair take?
- How long did the repair take
Explicación
The unknown span expresses duration, so the question begins with how long. Because took is a past lexical verb, did carries the tense and take returns to its bare form.
