Answer:
I sent a Heavy bulky box to my daughter who is a college student at an American university
Step-by-step explanation:
An adjective is a word that describes or qualifies a noun.
Coordinate Adjectives are adjectives that jointly qualify a noun. They cannot be separated by a comma without destroying their meaning or the meaning of the sentence.
1. Heavy Bulky = coordinate adjectives
2. American = adjective
