(Which one is the passive voice of #1?)

5. The homework will be finished this evening by him.

(Which passive sentence is correct? Are both OK as the passive form of #4?)

1 answer

#2 is the passive of #1. (#3 has a different auxiliary verb, "shall.")

Both 5 and 6 are passives of 4; 6 reads a bit more smoothly, than 5.
