Final answer:
Winston from George Orwell's '1984' would likely find the parts of Goldstein's book that critique the Party and discuss revolutionary ideas most exciting, as they contrast with his oppressive reality and offer hope for change.
Step-by-step explanation:
The part of Goldstein's book that Winston got the most excited about reading in George Orwell's novel '1984' is not explicitly stated, but it can be inferred that the most thrilling parts for Winston would be those that critique the totalitarian regime of the Party and propose revolutionary ideas. In the context of Orwell's narrative, such sections would likely offer a stark contrast to the oppressive reality Winston lives in, providing him with intellectual stimulation and hope for a different future. Given the nature of the book as a forbidden text within the novel, every page presents a certain level of excitement and danger for Winston, who is starved for truth and genuine human connection.
