Answer:
1. Dante's choice of rhyme scheme creates an effect of a melancholic, somber, and wistful atmosphere. It emphasizes the text's themes of spiritual suffering and journey, and a feeling of uncertainty. The rhyme scheme creates a sense of calmness and stability in the chaos that Dante experiences, as well as a sense of melancholy in the tragedy of those who are suffering.
2. When Dante says that he has “gone astray from the one true path”, he is referring to his spiritual journey - he has gone off-course and is on a path that is different within his religious faith. Evidence to support this is found in the text when Virgil reminds him that “only through sorrow may we reach our goal”, meaning that this journey of learning through hardship and suffering is ultimately necessary for Dante's knowledge and growth (page 142).
3. Based on the animals Dante encounters, it can be inferred that the territory beyond the mountain is one of chaos and disorder. This is supported by textual evidence such as the presence of "fierce wolves and lionesses that roared", which have violent connotations that imply a chaotic atmosphere (page 139).
4. In the context of the text, this phrase refers to those who are condoned to suffer in Hell, without any possibility of escape. They are content because they have accepted their fate and are resigned to the suffering they endure. Evidence to support this is found when Dante realizes that “the wretched had given up all hope” and were resigned to their punishment (page 143).
