Answer:
A drastic change can be brought by us together.
Explanation:
Hi there!
To change a sentence from active voice to passive voice, we must make the subject the action rather than the person/thing performing the action.
In this case, the people performing an action is we or us and the action is bringing a drastic change.
We can bring a drastic change together.
⇒ A drastic change can be brought by us together.
I hope this helps!
