Answer:
No
Explanation:
Long is the only adjective, for "dirt road" is a noun in itself. If they were seperated with commas, Ex. "That was a happy, merry song!" then they would be coordinating adjectives.
The correct answer is C. past tense.
Past tense is a grammatical tense used to describe an action or event that is done in the past. "Mixed" has a regular form "mix" and by adding "-ed" to it, it becomes a past tense.
