Identify the sentence that uses passive voice. a. this past christmas, my nephew was hoping to receive some gift cards for his game system. b. oscar wilde once stated to a customs official that he had nothing to declare but his genius. c. the students are being instructed to use the side entrance to the dorm until further notice. d. over 5,000 people, many of them having driven overnight, attended the concert in new york.

The correct answer is C. The students are being instructed to use the side entrance to the dorm until further notice.

Explanation:

In the passive voice, it is common the object of the action is presented first, then the main verb and finally the subject, although this is often omitted. In this way, the subject is less important or is passive. In the case of sentence "The students are being instructed to use the side entrance to the dorm until further notice" this is in passive voice because in this case the object "the students" which are the ones affected by the action are presented first, additionally, the verb construction "are being instructed" show the students are not performing the action, but this is performed by a subject that has been omitted, which is a characteristic in the passive voice.

the correct answer is the first option "the bolkshevik revolution". the passage makes reference to many of important events that occured in the revolution, such as the assemblies, in this case the animals are gathered in an assembly after a protest, the murder of fellow partners, the speeches given by the leader of the revolution, among other aspects. the last choice is possible, but in this passage in particular it is not emphasized the fight between the characters, that is the two pigs, that represent lenin and stallin.
