Here are some potential research problem statements based on the questions:
1. Identify and compare three sources of knowledge and how they contribute to the research process.
2. Evaluate four key considerations researchers must address when selecting a research topic and how these ensure a study remains feasible and manageable.
3. Describe four characteristics of a well-defined research problem statement and how these ensure the specific question to be addressed is unambiguously communicated.
4. Formulate a clear and researchable problem statement regarding the increasing number of ship collisions despite modern navigation systems by developing a mathematical model to calculate ship stopping distances.
