• 6. States can prevent war if they decide to resolve conflicts peacefully. (It is possible for states to prevent war.)
• 7. You will have better relations with people if you resolve a conflict peacefully. (This sentence implies a future outcome, making 'will' the most appropriate choice, though it's not in the provided options. If forced to choose from the options, 'can' or 'may' would suggest possibility, and 'should' or 'must' would suggest obligation, none of which perfectly fit the conditional nature of improved relations.)
• 8. You can learn about conflict resolution if you read books about conflict. (Reading books provides the ability to learn.)
• 9. You will have more friends if you learn to resolve conflicts peacefully. (Similar to sentence 7, this implies a future outcome. 'Will' is the most fitting, but not an option. 'Can' or 'may' would indicate possibility, and 'should' or 'must' would indicate obligation.)
