Without knowing if there are answer choices to this question, I will say that the Protestant Reformation changed the religious landscape of Europe by dividing Europe with confessional and territorial lines. This was a time of religious turmoil that led to many wars. Good luck :)
Americans started to hate the war (woo go peace core) and eventually we left Vietnam and Johnson didn't try his luck for getting his second term lol
To answer your question, the answer is C.Economic Depression because Portugal,France,Great Britain, and Belgium are all mostly about Colonialism.
