"If the play takes place in the past, why are the main characters fighting giant evil in the third act?"
Explanation:
The above sentence is the best sentence that uses historical context to develop characters in the story. In the given passage, the above sentence tries to reveal that as a result of the play taking place in the past, the main characters shouldn't be fighting a giant evil. This sentence actually reveals that the characters should fight evil if the play was taking place in the present. Therefore, this develops the characters in the play.
Historical context talks about the social, economic, or environmental situation which actually influenced what happened at that particular time. The historical context shows that the characters would not fight against evil if the play took place in the past.
