Answer:
Nihilist- philosophy.
Impeccable- outfit.
Indigenous- plant.
Step-by-step explanation:
As given in the question, the words on the left are adjectives while the ones on the right are nouns. And to give a complete phrase, the adjectives must be matched with the noun that makes a meaningful phrase.
1. A nihilism is a philosophical view that expresses negation towards a certain way of life and does not believe in any religious faith or meaning of life. So, it will be paired with "philosophy".
2. Impeccable refers to a flawless appearance, behavior, or any form of living that is perfect. So, in that sense, it can be paired with "outfit" to refer to a perfect outfit.
3. The term "indigenous" refers to a thing that is local, found only in some particular areas. It usually refers to something that is available in some areas and is native. Thus, it will be paired with "plant" to refer to a plant that is local and native.
