When will the car be washed? Why will the letter be written in French? Where will the flowers be planted?

Passive Voice Transformation

The task is to rewrite the following sentences in the passive voice:

1. When will the car be washed?
2. Why will the letter be written in French?
3. Where will the flowers be planted?

Note: These sentences are already in the passive voice. The auxiliary verb 'will be' followed by the past participle indicates the passive construction. Therefore, no transformation is needed.
