Which word in the sentence is a proper adjective? In Texas, we dipped crunchy chips in spicy Mexican salsa. A. Texas B. spicy C. crunchy D. Mexican
The correct answer is D. Mexican.
This is because Mexican here is an adjective, not a noun. It describes the origin of the salsa, not a person who is from Mexico.
The answer would be D because the word Mexican is modifying salsa. It is telling what kind of salsa it is. It begins with a capital letter indicating the word Mexican is a proper adjective.
