A fragment is a group of words that does not express a complete thought or lacks a main clause. In the context of the provided phrases, the phrase "Unless he leaves early" stands out as a fragment because it cannot stand alone as a complete sentence. It introduces a conditional clause, but it is dependent on another part of the sentence to convey a full idea, indicating that something would happen if he leaves early.

In contrast, the other phrases consist of complete thoughts. The first phrase provides a complete reason for why he can't rent games, the third gives a full context regarding the pizza and the decision to order more, and the fourth compares two choices with a complete structure. Understanding the structure of these phrases helps identify which one fails to provide a standalone meaning, thus highlighting the presence of a fragment in the second choice.
