Scholars have argued that Western and Eastern Europe were intrinsically different from each other between 1945 and 1989. To what extent was this true?

Question: Using P&H Chapters 16-22 and other appropriate materials from Unit #3, answer this question: Scholars have argued that Western and Eastern Europe were intrinsically different from each other between 1945 and 1989. To what extent was this true? To what extent was it not true? I would suggest a thesis that answers the question in three clear points, so perhaps “Eastern and Western Europe differed in A and B but were similar in C“or something like that.
