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?

hello answer is b i hope that helepd.

so, based on the research i've done. the u.s. government were always on a wild goose chase just to take down castro. he then retired his trone to his brother raul in 2008 due to some health issues. so it's obvious your answer would be:

castro had no allies from which he could receive aid.

hope this and have a fantastic day!
