Question

Which excerpt is a simile that indicates a thoughtful mood? “Let seed be grass, and grass turn into hay:” “(I measure time by how a body sways).” “These old bones live to learn her wanton ways:” “I swear she cast a shadow white as stone.”

Answer 1

The answer would be the last option, "I swear she cast a shadow white as stone." 

Answer 2

A simile is first defined as a type of speech that uses one thing or phrase with comparisons to things of an unrelated kind, often in order to make a more vivacious description. So of the phrases above, only the last one (I swear she cast a shadow white as stone) would be considered a simile, as a shadow white as stone takes two unrelated things and uses them in an interesting way.
