Answer :
The newspaper is brought by Sima.
Explanation :
In the active voice, the subject (Sima) performs the action (brings) on the object (the newspaper).
In the passive voice, the object (the newspaper) becomes the subject, and we use a form of "be" (is) followed by the past participle of the verb (brought), and add "by" to indicate who performed the action.
So, "Sima brings the newspaper" becomes "The newspaper is brought by Sima" in the passive voice.
