There are no choices listed but if there is no separation of
powers in a government then that means that power will be in the hands of a
single entity. Even if there are
branches in that government, the one that wields the most power will be the one
ruling the country and with that there is a danger of abuse of power and suppression of human rights.
The prehistoric era predates writing. Human progress included primitive tools and weapons, clothing, fire, cave art and burial of the dead. During the Old Stone Age, human beings were learning, but they were learning slowly. Then around 10,000 years ago progress began to speed up, with developments like agriculture, the domestication of animals, the creation of permanent villages and cities, etc. Writing began to appear around 5,000 years ago (around 3,000 BC) and that may be the beginning of what we call history, since we begin to know what people were thinking as well as what they were doing.
The Romans had conquered Greece. So, the Romans used many Greek ideas and incorporated it into their civilization.
