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. which phrase indicates a change in mood within the excerpt? “struck a few impressive chords” “smiling shamefacedly at his own credulity” “a fine crash from the piano” “interrupted by a shuddering cry"
