## Sub-questions

Often a main question is too complex to be answered in one go. That is why you split it into sub-questions. It makes the main question easier to manage.

Sub-questions always answer a specific part of the main question. Collectively, the sub-questions answer the main question. Questions that do not contribute towards answering the main question are not relevant.
Example

Your main question is:

“Which modifications to public transport are needed to ensure that the growing number of tourists in Amsterdam can move around more efficiently?”

You have now thought up a number of sub-questions:

1. Which modifications have been made to the infrastructure in Amsterdam in the last five years?
2. How many tourists come to The Netherlands?
3. Does the ease with which tourists can move around Amsterdam compare well to other Dutch cities?
4. Which modifications have been made to public transport in the last five years?

These sub-questions certainly have their flaws. What is wrong with these sub-questions, and what would you do differently? If necessary, write down your suggestions!
