c) hyperbole
A hyperbole is an over-exaggeration. In this phrase, it is highly unlikely that the little city in Georgia has been sleeping for "forty thousand years" especially considering that the United States is only 242 years old. If personification were an option, it would also be a great choice. Personification is giving non-human thing human-like traits. In this phrase, the city (non-human) is being given a human trait (dozing).
The other options: an allusion is a reference to another piece of literature or other published work. A flashback is an interruption that tells about something that has already happened. Rhyme is a group of words that sound similar (bone, cone, phone).
B - Bravery
Although you didn't provide the passage, there are various reasons as to why bravery is the answer.
A is incorrect as the Odyssey never focused on democracy as shown through kings of many lands since Odysseus himself was the king of Ithaca with his son being the rightful heir of the throne.
C, knowledge, is incorrect as characters in the Odyssey never valued knowledge. The Odyssey was filled with battles and overcoming hardships, not gaining knowledge and wisdom, thus ruling out C as the possible answer.
D, relaxation, is an answer you can immediately rule out. Throughout the Odyssey, the stories and the movies, you can see that all characters are constantly bustling and working for whatever they hope to accomplish. Although they may value relaxation, they seem to value work more so.
Hope this helps!
