Answer:
Justice, quality - abstract nouns
Explanation:
Nouns are words we use to name everything we know of - things, living creatures, places, actions, qualities, states of existence, ideas, etc.
Concrete nouns are nouns used to name things we can detect by our five senses (sight, hearing, smell, taste, and touch). Abstract nouns are the opposite - they name things we can't detect by our senses, such as concepts, ideas, experiences, states of being, qualities, feelings.
The given sentence contains two nouns - justice and quality. Both of them are abstract nouns.
