Answer 1

The sentence that contains coordinate adjectives that should be separated by commas is:

"The bus was hot, crowded, and loud, so we decided to get off and walk."

In this case, "hot," "crowded," and "loud" are all adjectives that independently describe the bus and are therefore coordinate adjectives.
