Answer:
City, laws, justice, kings.
Explanation:
To answer this question, you must first know what a <u>noun</u> is, which is a person, place, or thing. Look through the list, and you will find out that <u>expected</u> is not a person, place, or thing; it is a verb.
Now you're left with Mesopotamia, city, laws, justice, and kings. A quick tip amongst nouns is that <em>capitalized</em> and <em>eponymous</em> (something that is given a name to) nouns are most probably proper nouns, which is not what we're looking for here. Cross out <u>Mesopotamia</u>, and you are finished.
Hope this helps! :)
