Step-by-step explanation:
Articles describe the nouns that they precede. In English, there are only three articles: the, a, and an. However, the three are not interchangeable; rather, they are used in specific instances. 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?"
I bolded your adjectives and underlined your articles so that there's no confusion.
