On the passage of poems the author basically implies several stages of man, in other words humanity as a race and the decisions which in turn became our sins and lastly our human faults derived from wrong perceptions and ultimately corruptible mistakes that took a toll on our primary parents' descendants family.
The question ask to choose among the following choices the possible answer that could support the said question that ask the word that best describes the authors view of humanity and the best answer among the choices are in letters C. pessimistic and D. realistic. I hope this would help
