Coordinate adjectives
Coordinate adjectives have the same degree of importance in the structure and describe the same noun. They also must be separated by a comma. To know if we are dealing with coordinate adjectives, we can try inverting their order.
If the sentence still makes sense, they are coordinate. If the inversion is not possible, they are not coordinate adjectives, and a comma should not be used. Let's test and compare two of the options:
- A red, rusty gate --> A rusty, red gate → Correct. Both adjectives refer to "gate" and can be inverted.
- A bright, pink minivan --> a pink, bright minivan → Incorrect. The adjective "bright" refers to "pink", not to "minivan".
With the information above in mind, we can choose letter B as the correct option.
