The correct answers are Complete Subject: The ambassador from Cuba / Complete Predicate: pounded his fist on the table
Step-by-step explanation:
In grammar, the subject of a sentence refers to the agent acting; on the other hand, the predicate includes the verb and other words that complemented it. Additionally, the complete subject includes the main word of the subject and all words that describe it and similarly, the complete predicate includes the verb and all words related to it. This means in the case presented the Complete predicate is "The ambassador from Cuba" because all of these words define the agent performing the action "pounded"; in the same way "pounded his fist on the table" is the complete predicate as it includes the main action and other details that explain it.
