Question

question 4 of 5
why is macbeth upset when he sees malcolms army carrying branches from birnam wood?
a. because the trees in birnam wood helped protect the castle
b. because one of the witches prophecies has come true
c. because he fears the army will set his castle on fire
d. because his wife will be sad that birnam wood has been destroyed

Explanation:

In Macbeth, the witches prophesy that Macbeth will not be defeated until "Birnam Wood moves to Dunsinane". When Malcolm's army uses branches from Birnam Wood as camouflage (making it seem like the wood is moving), this fulfills part of the prophecy. Macbeth is upset because a key prophecy of the witches (which he thought was impossible to happen) has come true.

Answer:

B. Because one of the witches' prophecies has come true
