Question

Ben growled when I walked into his room. He barked at me to close the door as he lumbered back to his desk. He is such a bear in the morning! Which figure of speech does the author use in the passage? A. simile B. extended metaphor C. personification D. epic simile

Answer 1

I believe the answer is B, an extended metaphor. 
It can't be A because similes are comparing two unlike things using the words "like" or "as", which will also eliminate D.
It can't be C because a personification is where an inanimate object is given human-like qualities. 

Throughout the entire passage, the author compares Ben to a bear and uses words such as "growled", "barked", "lumbered" which shows how the comparison between the two is prolonging throughout the passage. 

Answer 2

The answer is B. Extended metaphor
