Final answer:
There is no identifiable trend in how power shifts between groups in revolutions, but certain aspects such as the role of social media and unmet expectations tend to change. Each revolution is unique and influenced by different factors.
Step-by-step explanation:
When studying multiple revolutions throughout history, it is difficult to identify a specific trend in how power shifts from one group to another. However, there are certain aspects that tend to change from one revolution to the next. One aspect is the role of social media in enhancing communication and mobilizing people, as seen in the Arab Spring and Occupy Wall Street movements. Another aspect is the impact of unmet expectations and needs on the mood of the people, as highlighted by James C. Davies in his theory of revolution. It is important to note that each revolution is unique and influenced by various factors, making it challenging to pinpoint a consistent trend.
