Some rivers and seaports in russia can freeze for six to nine months out of the year. predict how this could affect trade and travel in russia and how russians may try to overcome this obstacle.

They could get stuck and be there for day's.

This is all you, but i can give you some topics that you could try. if it rained when you want to do something outdoors, it 'limits' that human activity. maybe you want to do an experiment that goes throughout the whole year and you have to have above freezing the entire year. this 'limits' your activity. i thought of those just off of the top of my head. something that gets to me that might be getting to you is you are thinking too hard about what to do. think simply, and if it is too simple, then bump it up just a little bit.

How is this a question? where are the answer choices?
