Answer:
The best answer to the question: Which statement is true of mystery, miracle, and morality plays, would be: They were meant to instruct the people.
Step-by-step explanation:
Morality plays, mystery and miracle plays, were all forms of vernacular drama that usually portrayed the events on the lives of a religious figure, like the Virgin Mary, or Saint Nicholas, but not necessarily people from the Bible. Created and performed during the Middle Ages, these dramas sought to teach people about the Catholic faith, its saints and figureheads, but later on, as Church and State began dissasociating, these took on a more lay tone. However, their being used as a teaching method, did not stop.
