Answer:
Sour & Green
Step-by-step explanation:
An adjective is a word that describes or modifies a noun or pronoun by providing more information about its characteristics, qualities, or attributes. In the sentence "Green apples are sour", both "green" and "sour" are adjectives. "Green" is describing the color or appearance of the apples, while "sour" is describing the taste of the apples. Adjectives are an important part of English grammar because they add details to a sentence and make the meaning more specific and interesting.
