In christopher marlowe's "the tragical history of doctor faustus", why did faustus begin to believe that human salvation was impossible?

Based on the story of "The Tragical History of Doctor Faustus", Faustus signed a contract with Mephistophilis, even though few signs appeared before him that he should not agree with the contract. He chose to be on the side of the devil and did a lot of bad things, without thinking what will be of him after the contract. All what he did make him guilty, and gave him the thought that after all what he did, it is too late for him to be forgiven.

the correct answer is the first option "the bolkshevik revolution". the passage makes reference to many of important events that occured in the revolution, such as the assemblies, in this case the animals are gathered in an assembly after a protest, the murder of fellow partners, the speeches given by the leader of the revolution, among other aspects. the last choice is possible, but in this passage in particular it is not emphasized the fight between the characters, that is the two pigs, that represent lenin and stallin.

for me, balancing all your work/homework is the hardest part in high school and the exams.
