Based on your topic and literature review, you can start generating some possible research questions that interest you and address a specific aspect of your topic. You can use different strategies, such as brainstorming, mind mapping, questioning, or using frameworks, to generate ideas. You can also consult your peers, mentors, or experts for feedback and suggestions. After you have a list of potential questions, you need to evaluate and refine them according to the following criteria: clarity, focus, relevance, originality, and answerability. You should choose a question that is clear and concise, focused and specific, relevant and significant, original and innovative, and answerable and feasible. You should also make sure that your question aligns with the goals and requirements of the grant program that you are applying for.
