Answer:
(1) “perfectly organized classroom library in random order...”
(2) “deafening silence”
Explanation:
(1) it is an oxymoron because the sentence contradicts itself the library is in a “random order” random contradicts the word “order” as this implies something is neat and together.
(2) this is an oxymoron because it implies silence is so over powering that it feelings like it is actually extremely loud or in this case “deafening”
