A victory over the U.S." and "access to lots of oil" are the two reasons what the <span>Soviet Union stood to gain if it controlled Afghanistan. The correct options among all the options that are given in the question are the third and the fourth options. I hope that this is the answer that has actually come to your help.</span>
Constantine is very important in the world history by the changes he made towards the Christianity and how he set up the scene for its progress. If it wasn't for him, the Christianity might have never been legalized, and to become the dominant religion in Europe, and afterwards in the Americas, and parts of Africa. Since the Christianity has had huge effect in the political sphere in Europe, and it is a big global player even nowadays, the world would for sure be a much different place if it never spread and gained power and followers. Maybe the paganism would have existed on a large scale, maybe another religion and its principles and morals would have become dominant ans shape the world, we can only guess, but it is sure that it was not going ot be the same.
It would be good to know the context of your question. When you say "based on the passage," perhaps you could attach a screen shot of the passage you're looking at.
Nevertheless, even without such context, I would lean toward saying the answer is that "the Soviet government would do whatever it could to stay in power." I'm guessing you're talking about events as the Soviet Union was nearing its dissolution and Boris Yeltsin was leading Russia in a move to declare its own sovereignty separate from the USSR. The Soviet leadership did not give in to that movement willingly.
Republic was the form of government that developed under the Roman Republic and it had <span>the greatest impact on the democratic tradition. It is basically a type of indirect democracy in which the people had the right to chooses the people who had the power of making government decisions. I hope it helps you.</span>
