Sudden changes in society are often described as revolutions. advances in technology can result in revolutions in science and the workforce. dissatisfaction with a government can lead to a political revolution. under what circumstances is it likely that these changes will occur? are there circumstances in which these changes should not occur?

I think these changes are more likely to occur during a war or maybe when the president or someone important says something that people don't like. Also, when people are under stress they are more likely to start a revolution. I don't think there would be circumstances where people won't make a revolution. People will always feel unsatisfied with the government, so there will always be changes too.
