Read the sentence. someone sang a solo during the holiday concert. the best reason to revise this sentence using the passive voice is that the name of the singer is unknown. the kind of song being performed is unknown. the length of the concert is unknown. the type of holiday being celebrated is unknown.

The answer to the given question above would be the first option. The best reason to revise this sentence using the passive voice is that the name of the singer is unknown. This entails that the speaker does not consider the name of the singer to be relevant information, or else, the fact that a solo was sang is more important than the singer's name.  

When using the passive voice, the object of the active sentence becomes the subject; therefore, the action is highlighted instead of the doer of the action.
