A. The loud, boisterous party went on until midnight.
B. The tiny, broken clock sat on the shelf.
C. The bright, yellow dress caught her eye.
D. The smooth, polished surface reflected the sunlight.

Answer 1

The adjectives are not coordinate in option B: "The tiny, broken clock sat on the shelf."

In this case, "tiny" describes the size and "broken" describes the condition of the clock, and they do not equally modify the noun (the clock) in a way that would allow for a comma between them. Therefore, no comma should be used.
