Final answer:
Based on the given information, there is no evidence to support the claim that Hassan vows his loyalty to Amir again.
Step-by-step explanation:
The question is asking whether Hassan vows his loyalty to Amir again, and whether this statement is true or false. To answer this, we need some context. The first reference provided is a quote from Nathaniel Hawthorne's story 'The Birthmark.' While this quote may introduce the idea of loyalty, it is not directly related to Hassan and Amir. The second reference is a news article about Amir Khan Muttaqi, who is a government official in Afghanistan. Again, this does not provide any information about Hassan vowing his loyalty to Amir.
The final reference is from 'The Secret History of the Mongols' and talks about Jamukha and Temujin pledging their eternal friendship and loyalty to each other. This reference gives us an example of loyalty between friends, but it is not about Hassan and Amir. Based on the given information, we do not have any evidence to support the claim that Hassan vows his loyalty to Amir again.
