Most scholarly research examines fairly narrow topics and looks at relationships between concepts. For example, cell phones is a pretty broad topic, but looking at the impact of cell phone manufacturing on the environment might be a more manageable topic.
There are many ways to narrow a topic that is too broad by asking one or more W questions. Let's use cell phones as an example:
Use W questions, to develop a research question on the topic of cell phones:
Research Question: How can precious metals in cell phones be recycled more effectively?
For Discussion: Why is this a successful or unsuccessful research question? Is it an improvement on this previous question? How beneficial or problematic is cell phone use for our society?
