HELP BRAINLIEST AND 40 POINTS
Read the excerpt from “The Monkey's Paw.”
Mr. White took the paw from his pocket and eyed it dubiously. "I don't know what to wish for, and that's a fact," he said, slowly. "It seems to me I've got all I want."

"If you only cleared the house, you'd be quite happy, wouldn't you?" said Herbert, with his hand on his shoulder. "Well, wish for two hundred pounds, then; that'll just do it."

His father, smiling shamefacedly at his own credulity, held up the talisman, as his son, with a solemn face, somewhat marred by a wink at his mother, sat down at the piano and struck a few impressive chords.
"I wish for two hundred pounds," said the old man distinctly.

A fine crash from the piano greeted the words, interrupted by a shuddering cry from the old man. His wife and son ran toward him.
