Here are the effects that the foreshadowing in Friar Laurence's warning to Romeo had:
A. It keeps the audience engaged in the plot by suggesting more potential conflict in the story.
C. It creates suspense as the reader wonders why Friar Laurence would utter this warning.
E. It provides a clue that something tragic will happen to the lovers later as the story progresses.
B is incorrect because it is a foreshadowing, not an explanation. D is incorrect because the friar cannot predict the future, it is a warning.
Hope this helps
