Transform the direct question 'Where is the depot?' into an embedded clause after 'Could you tell me'. Rewrite the exact fragment 'Where is the depot' in the blank: Could you tell me ___?
Richtige Antwort
where the depot is
Erklärung
Embedding removes the inversion found in the direct question, so the subject the depot moves before is. The wh-word remains at the front because the missing information is still a place.
