read the sentence.\nsomeone sang a solo during the holiday concert.\nthe best reason to revise this sentence using the passive voice is that\n○ the name of the singer is unknown.\n○ the kind of song being performed is unknown\n○ the length of the concert is unknown\n○ the type of holiday being celebrated is unknown
Answer
Answer:
A. the name of the singer is unknown
Brief Explanations:
In passive voice, the focus shifts to the action and the object (here, "a solo" and the action "was sung"), which is useful when the doer (singer) is unknown. The other options relate to song type, concert length, or holiday type, which aren’t reasons for passive voice use here.
