Answer: C. Compare two unlike things.
Both metaphor and simile are figures of speech used solely for comparison. Both of these figures of speech are often confused as a result of their similar use. While simile uses the words “like” or “as” to compare two objects, metaphor operates on direct comparison. An example of simile is “life is like a bed of roses” while an example of a metaphor is “life is a bed of roses.” In other words, metaphors are entirely rhetorical while similes tend to feel more logical.
