Final answer:
Option (b), 'It was a movie about a city girl who is adopted by a farm couple,' is the sentence that uses the passive voice, with the city girl as the subject being acted upon.
Step-by-step explanation:
To determine which sentence uses passive voice, one must look for a few key characteristics: the subject being acted upon, the use of a form of the verb 'to be,' and the presence or possible addition of the preposition 'by.' In the choices given:
- a. I will return the video tomorrow. (Active)
- b. It was a movie about a city girl who is adopted by a farm couple. (Passive)
- c. She grows up in the country. (Active)
- d. What she learns on the farm changes her forever. (Active)
Option (b) 'It was a movie about a city girl who is adopted by a farm couple' is the sentence that uses the passive voice. Here, 'is adopted' is a form of the verb 'to be' combined with the past participle 'adopted,' and we can infer the existence of the prepositional phrase 'by a farm couple.' The sentence indicates that the action of adopting is being done to the 'city girl,' thus making her the subject being acted upon, which characterizes the passive voice.
