Answer:
"O miserable abundance, O beggarly riches!" – John Donne ➡️ Oxymoron
"What a pity that youth must be wasted on the young." – George Bernard Shaw ➡️Paradox
Explanation:
The literary devices are oxymoron and paradox.
Oxymoron is known as a rhetoric device which is usually self-contradicting; the words seem to contradict each other.
Like the sentence: "O miserable abundance, O beggarly riches!", An abundance that is miserable is self-contradictory. "Beggarly" means that there is lack and poverty. But yet riches is attached. So, it's an oxymoron.
Paradox is known to be a logically self-contradictory statement. It tends to go against common sense but yet somehow it looks true.
The sentence: "What a pity that youth must be wasted on the young." - youth has to do with being young but yet the statement says it is wasted on the young; that's self-contradictory but can be true.
