While the social role of epic singers may be touched upon, the passage does not primarily focus on analyzing their societal functions. Instead, it emphasizes the singers' personal views and artistic expressions, making this choice less fitting as it shifts the focus away from their subjective experiences.

This option suggests an exploration of external perceptions and neglect of epic singers, which is not the main thrust of the passage. The text does not delve into the reasons behind the reception of their art but rather centers on how the singers themselves regard their craft.

Though the passage may reference the interplay between epic songs and poetry, its main focus is not on this relationship. Instead, it highlights the singers' views of their own artistic practices, making this choice peripheral to the primary purpose of the passage.

This choice implies a critical evaluation of existing scholarship, which the passage does not undertake. The text is more concerned with the singers' perspectives rather than challenging or critiquing scholarly interpretations of their art.
