Answer:
"Ethan Frome" is a novel by Edith Wharton that was first published in 1911. The story tells us about the life of Ethan Frome, at least his life before and after his "accident" 24 years prior to when the story is told.
The answers then, to the questions, would be as follows:
4. The word that best describes the mood both of the Prologue and Chapter I, would be: C: Severe. This is seen by the words that are used by the narrator and the people he encounters, as well as they way he describes what he sees around him. The sense one gets by reading these first two parts is of something severe, even gloomy.
11. The conflict between Zeena and her husband, Ethan, over Mattie cannot be easily framed into one type. There is a combination between man vs. self and man vs man. Man vs self, because Ethan is faced by the conflict of having feelings for his wife´s cousin, but being stuck with his life as it is, and not daring to do anything that might go against the status quo. Man vs. Man arises between Zeena and Ethan as the two know about the feelings between Ethan and Mattie, but the two struggle more on the ground of Mattie´s inappropriateness as a housekeeper and helper for Zeena, and Zena´s belief in the lack of necessity for Mattie.
12. Foreshadowing is one of the most evident literary devices used by Wharton, probably throughout the entire book. But this foreshadowing is most clear at the beginning, especially in the first chapters, when Ethan foresees probable outcomes for his future and then at the end, in the irony of how the future has evolved.
14. The biggest irony he sees is that the headstone proclaims that Ethan´s namesake, another Ethan Frome, and his wife, ironically named Endurance, were able to stay together peacefully for fifity years. Given the conflicting situation between him and his wife Zeena, which have made Ethan feel like he has already been married for fifty years, and the fact that he has been feeling dragged down by his marriage, he wonders if, as their counterparts, they too will be remembered in their epitapths as having been able to dwell "peacefully" together
