Final answer:
Ponyboy is an unreliable narrator because he is dishonest and portrays events from his biased perspective, making him unreliable in presenting a complete and accurate account of the story.
Step-by-step explanation:
Ponyboy is an unreliable narrator because he is dishonest. He may not always tell the facts of the story correctly, skewed by his own biases and perspectives. One example of this is when he portrays the Socs as the sole antagonists, failing to acknowledge the actions of the Greasers that provoked their conflict. Ponyboy's limited understanding and subjectivity make him an unreliable narrator.
