Two towns have about the same latitude and elevation. one town is on the coast and the other is far inland. how would the summer weather of the inland town most likely be different from the weather in the coastal town?

The inland town would be a little warmer because the air coming inland off the coast (water) is cold/cool, which makes the coastal town cooler and maybe even windier. 

Ibelieve it is answer b. provides military aid.

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.
