In at least 300 words, answer the following question:
Focusing on at least three of the four course themes of religion, government, social class, and gender roles, explain which of the three cultures (the Byzantine Empire, western European kingdoms, and the Islamic Caliphate) between 500 and 950 was the truest heir to the Roman Empire and which one was the most different from the Roman Empire? 
Suggestion for formulating a clear answer: Instead of describing two cultures separately, you should compare all three in terms of at three of the four course themes in order to arrive at your conclusion about which culture was the truest heir to the Roman Empire and which culture was the most different from the Roman Empire. You should first compare them in terms of one of the themes. For example, you could compare them in terms of government to explain which culture had the most in common with the Roman Empire in terms of its government and which one had least common in terms of its government. Then you should do the same for two other themes. Then based on your conclusions about three of the themes, state your conclusion about which culture was the truest heir to the Roman Empire and which one was the most different from the Roman Empire.
