Final answer:
The differing reactions of the boys to the story of Rostam and Sohrab could be due to cultural differences, varying familiarity with the story, and the personal emotional impact that the story has on each boy.
Step-by-step explanation:
The boys react differently to the story of Rostam and Sohrab based on several factors that influence the interpretation of narratives. One reason could be that cultural differences provide distinct frameworks through which individuals understand and relate to stories. Another reason might be varying degrees of familiarity with the story; if one boy is hearing the story for the first time while the other has heard it before, their reactions are bound to differ. The emotional impact of a story can vary depending on an individual's personal experiences, which is also why one boy might be profoundly affected and the other less so.
Powerful literature like the story of Rostam and Sohrab is subject to multiple interpretations. These interpretations can be influenced by personal experiences and identity, which reflect how we connect to the characters and their struggles. This concept is akin to how each production of Shakespeare's Hamlet or any other classic narrative differs; it's shaped by the unique perspectives and artistic choices of the directors or storytellers.
