Final answer:
The sentence is in passive voice because the subject 'the dog' is acted upon, there is a form of the verb 'to be' present, and the preposition 'by' indicates who is performing the action.
Step-by-step explanation:
The sentence 'The dog was pulled down the street by its owner' is in the passive voice. To determine if a sentence is in passive voice, we can look for a few key characteristics:
- The subject of the sentence is being acted upon rather than performing the action.
- There is a form of the verb 'to be' such as 'am,' 'is,' 'are,' 'was,' 'were' coupled with a past participle (-ed or -en form of a verb).
- The sentence might include the preposition 'by' followed by the noun phrase denoting the actor.
In the example, 'the dog' is the subject that is being acted upon, 'was pulled' is the past tense of 'to pull' combined with 'was,' which is a form of 'to be,' and 'by its owner' indicates who is performing the action. If rewritten in the active voice, the sentence could read, 'The owner pulled the dog down the street.'
