Which excerpt from Act 2 of The Monsters Are Due on Maple Street best states the overall message? As they stand there, fearful, apprehensive, mothers clutching children, men standing in front of wives. "I do know who it is. I know who the monster is here. I know who it is that doesn't belong. I swear to you I know." "With few variations. They pick the most dangerous enemy they can find . . . and it's themselves. And all we need do is sit back . . . and watch." "And the pity of it is . . . that these things cannot be confined to . . . The Twilight Zone!"
