Macbeth initially rejects the witches' prophecy as meaningless. He doesn't believe it.
It's only when one of their predictions, that Macbeth was to become the thane of Cawdor, comes true, that Macbeth believes the prophecy of the witches, thus putting in motion the plot of the play (Macbeth trying to fulfill the prophecy that he is to become the king).
The answer happens to be passive, I just took the test on edg. and this is correct. I don't understand why you have the wrong answer marked brainliest and approved but please rate 5 stars on this answer so people don't make the mistake.
