Focus on the issue and set up a debate
Example:Can the genetic modification of food provide a solution to global poverty?
Overall topic: Genetic engeneering
Focus: Genetic modification of food
Debate: Yes, it is. <-> No, it isn't.
For every question you create, you always need to be able to explain what the issue is and identify a debate, so that you can develop perspectives and reach a conclusion which chooses between them.
