Answer:
4. Complete predicate
Step-by-step explanation:
The term that best describes the capitalized sentence is "complete predicate"
In English language, a sentence is divided into a complete subject and a complete predicate. The complete subject consists of all the words that talk about who or what the sentence is.
Complete predicate is the one that actually contains the verb and all the words that tell what took place in the sentence.
"...PLAYED A SAD SONG ABOUT LOST LOVE." is a complete predicate because it talks about the action taking place and all the other words.
