Answer:
John Adams
Step-by-step explanation:
In order for the first sentence of the paragraph to make sense, it must indicate who performs the main action “acquired,” in other words, it must have a “subject.” The question provides two possible subjects (two nouns): Peacefield and John Adams, but Peacefield is a place, a property, a thing that can not “acquire” something else. John Adams, on the other hand, is a person, someone who can acquire things.
