Step-by-step explanation:
An adjective describes or modifies a noun. It provides further information about a noun, indicating things like size, shape, color, and more. Adjectives can also modify pronouns. They answer questions like, "Which one?," "How many?," "Whose?," and "What kind?"
The nouns weren't underlined in the example, so I made do. Your adjectives are bolded.
