Question

1. select the sentence that correctly uses a comma to separate a list of only two items.

the long, red dress swirled gracefully around her feet.
the red dress, and silver shoes match perfectly.
they danced, laughed all night long.
the girl, and her date both wore red and silver to the dance.

Explanation:

To determine the correct sentence, we analyze comma usage for two - item lists:

1. In "The long, red dress swirled gracefully around her feet", "long" and "red" are two adjectives (a two - item list) describing "dress", and the comma correctly separates them.
2. For "The red dress, and silver shoes match perfectly", when joining two noun phrases ("red dress" and "silver shoes") with "and", a comma before "and" is incorrect in a simple two - item list.
3. In "They danced, laughed all night long", "danced" and "laughed" are verbs, and this is a case of a comma splice (incorrectly separating two verbs in a compound predicate without a conjunction like "and" between them in the right way for this context).
4. For "The girl, and her date both wore red and silver to the dance", when joining two noun phrases ("the girl" and "her date") with "and", a comma before "and" is incorrect in a simple two - item list.

Answer:

The long, red dress swirled gracefully around her feet.
