Final answer:
The central conflict in 'Bonds Tested' can be likened to a man versus self conflict, such as seen in the narrative given by Mark Twain where he faces increasing self-doubt due to external pressures.
Step-by-step explanation:
The central conflict in the narrative of Bonds Tested is not explicitly given among the options provided in your question. However, based on the context provided, it seems to refer to a narrative where a character faces a challenge that creates a sense of uncertainty or doubt. Drawing from the Mark Twain excerpt mentioned, it resembles a situation where Twain is confronted with a task that he initially feels confident about, but as tension increases due to external factors (like Mr. Bixby sending more people), he begins to second-guess himself. This scenario illustrates a type of man versus self conflict, where the character is dealing with internal struggles of confidence and self-doubt.
In relation to the other points mentioned, Erik Erikson's developmental theory suggests that in the final stage of life, older people struggle with overcoming despair to achieve integrity. The term centripetal is defined as 'center-seeking'. In the ultimatum game, the main rule is concerned with the establishment of the offer. These points reflect various types of conflicts or challenges that can arise in different contexts.
