Which sentence contains coordinated adjectives that should be separated by commas

She is a smart, talented, and ambitious student.

When using coordinated adjectives, they should be separated by commas. An example of a sentence with coordinated adjectives that should be separated by commas is:

"She wore a beautiful, flowing, blue dress."

When determining whether to separate coordinated adjectives with commas, you can use the "FANBOYS" acronym as a guide. FANBOYS stands for coordinating conjunctions: for, and, nor, but, or, yet, and so. If the coordinated adjectives can be rearranged or if they can be connected with one of these coordinating conjunctions, then commas should be used.

For example, let's consider the sentence: "She has a beautiful, intelligent cat."

To determine if the adjectives "beautiful" and "intelligent" should be separated by commas, we can try rearranging the sentence: "She has an intelligent, beautiful cat." Since the sentence still makes sense in both orders, we can conclude that a comma should be placed between the adjectives.

Here's another example: "He wore a red and blue shirt." If we try to rearrange the adjectives, we get "He wore a blue and red shirt," which sounds a bit awkward. In this case, no comma should be used between "red" and "blue."

In summary, in cases where the adjectives can be rearranged or connected using coordinating conjunctions, separate them with commas. If the adjectives cannot be rearranged or connected, then commas should not be used.
