Kaiserreich vs Republik
republic
'die Republik' and 'das Kaiserreich' are political and historical opposites. A republic has no monarch; the head of state is elected for a certain period of time. An empire, by contrast, has an emperor or empress as head of state. 'Kaiserreich' can generally mean such a state, but it is also used especially for the German Empire from 1871 to 1918. So when it is about the form of government, ask: elected head of state or emperor? Based on that, choose 'Republik' or 'Kaiserreich'.
