Hello. I'll be grateful for your help.

1)Is it possible to use "deal with" in the same meaning as "solve" in the context "I hope they will solve the Middle East conflict"?
2)Which is the correct position of the preposition in the sentence "the region has been aspiring to independence or to(?)at least to(?)autonomy"?
3)Is it possible to use "help with -ing", for example "he promised to help with translating / cleaning / training the dog"?
4) Is it possible to use "nearby" in the context "I live nearby the town"?
Thank you very much for help.

1. Solve indicates a successful resolution, while dealing with indicates working with the problem(s), but not necessarily reaching a solution.

2. Second position
3. Yes
4. I live near the town.
