Read the excerpt from “The Monkey's Paw.” Even his wife's face seemed changed as he entered the room. It was white and expectant, and to his fears seemed to have an unnatural look upon it. He was afraid of her.
"Wish!" she cried, in a strong voice.
"It is foolish and wicked," he faltered.
"Wish!" repeated his wife.
He raised his hand. "I wish my son alive again."
The talisman fell to the floor, and he regarded it fearfully. Then he sank trembling into a chair as the old woman, with burning eyes, walked to the window and raised the blind.

Which word in the excerpt best shows Mr. White’s reaction to meeting his wife’s demand?
