Explanation: A simile is a comparison using the words "like" or "as." A metaphor is a direct comparison between elements that aren't obviously related, in order to create an image in the reader's mind. A paradox is a self-contradictory statement and personification is giving human characteristics to nonhuman objects. The given sentence is an example of personification, because it is saying that the sky (non-human object) is angry (human characteristic).
