This question already has an answer here:
The active voice is Will she tell us the truth ?
The passive voice has two options
Will the truth be told to us by her ?
Will the truth be told us by her ?
I.e. will "to" follow us in passive voice. It feels right to include to in passive voice.
Is this also correct?
Will the truth be told by her? Can we ommit "us" assuming that this is directed to people referred as "us"
