Final answer:
The provided text excerpts do not give information about Angela's plan to deceive Bayardo on their wedding night or why it failed, as they discuss various unrelated literary plots and characters.
Step-by-step explanation:
Based on the excerpts provided, it is not possible to distinctly answer why Angela's plan to deceive Bayardo on their wedding night failed as they do not contain information related to a character named Angela or an event about her wedding night with Bayardo. The text excerpts seem to come from various literary works, discussing different plots and characters, such as the joy of Gil-Dong and his encounter with a maiden, a deceitful act planned by a concubine, a Roman contemplating a lost possibility of marriage, and a situation involving a character named Bernice as she coped with a social event.
For a comprehensive analysis of why Angela's plan to deceive Bayardo failed, the text would need to provide specific details about her plan, the actual wedding night, and the outcomes or reactions of the characters involved. Without that context, it is impossible to give accurate reasons for the failure of the plan.
