A study of revolutions would most likely lead to the conclusion that pre-revolutionary governments:

fail to meet the political and economic needs of their people.
refuse to modernize their armed forces with advanced technology.
are more concerned about human rights than the governments that replace them are.
attempt to bring about the separation of government from religion.

fail to meet the political and economic needs of their people. This is because revolutions often arise due to widespread dissatisfaction with the status quo, including lack of political representation, economic inequality, and social injustices. Governments that are unable or unwilling to address these issues are more likely to face revolutionary movements.
