Answer:
Oxymoron:
1: O miserable abundance, O beggarly riches!
Paradoxes:
2: What a pity that youth must be wasted on the young.
3: I can resist anything but temptation.
4: How is it possible to have a civil war?
Explanation:
Oxymoron:
It is a figure of speech in which apparently contradictory terms appear in conjunction.
e.g Fully empty, living death, O loving hate.
Based on this definition only "O miserable abundance, O beggarly riches!" falls under the category of Oxymoron.
Paradox: It is similar to oxymoron, but it is usually a statement with logically contradictory statements which on investigation may or may not be logically true.
e.g "Everything I say is lie" , Barber Paradox: "A male barber shaves all and only those men who don’t shave themselves. Does he shave himself?"
As we can find out there are no contradictory terms/words, but the statements which may contradict each other.
Based on the above, we conclude that sentence 2, 3 and 4 are Paradoxes.
