Hey there,
Your question states: Which best states the goal of this declaration? Based on my research and understanding of this question listed above, Your correct answer would be <span>The Soviet Union should be given additional territory in Eastern Europe. The reason why so, this would be because this can actually help the Europeans. All the other options dont really make sense on how it could actually be there goal for the declaration. So based on the goal, it would make more sense for the Soviet Union to give a little territory.
Hope this helps</span>
