Im not sure Im able to make a strong argument as to why one of these answers is better than another (between B and C), and Id like help if anyones willing...
Lesky believes that a path or decision is equally constrained by both divine and personal influences. While the gods provide the path (chosen for their own reasons), the individual adheres to it or not. "Tragic action is bound by the constant tension between a self and superhuman forces."
Rivier concedes that these superhuman forces are the primary source of the tragic dimension present in the drama...this force is experienced both internally and externally and thus, the notion that an individual has valid personal autonomy is not entirely accurate.
B) wonders whether or not the protagonist acknowledges the role of the deities in their life. Lesky would state yes, Agamemnon clearly understands through the messages presented by Artemis, that the only way to acquire the winds to blow his ships into battle would be to sacrifice his daughter. Rivier, on the other hand, would argue that the protagonist does not understand the superhuman forces at work...the decision one makes is ultimately the work of an external divine imposition. Does the protagonist understand this?
C) wonders whether or not the protagonist's desires have relevance to the outcome of the drama. I believe that Lesky would state that yes, Agamemnon can make the decision to either fulfill his desire to wage battle, or fulfill his desire to remain a father to his child. River might concede that there is no such relevance...the path has already been dictated and chosen.
I originally went with B, but BR'd C...some further explanation could help.
Thanks in advance...
