A surrender, a revolution, or a moonwalk is dated as that event, not as the whole decade around it. The questions do not ask who “won” a moral argument. They ask when something happened.
Each explanation names the public reference checked on 6 October 2026. The quiz is for entertainment and does not compare your score with anyone else. It also does not ask you to guess how an average person would do. Read the wording with care. There is no time limit. Take the questions one at a time.
