When thinking about what is and what may be, it is often useful with challenging questions and ideas.
The purpose can be to make us find and explain the basics, or to make us think in other perspectives. That can give people a better understanding of functions and changes. And other positive effects.
A simple example is that I tell you it's good for you to read my articles. "Why?", you wonder. Will you be satisfied with me saying that it can improve your life? Probably not, so you want to know "In what way?". That challenges me to think about my purpose with the articles and whom I write for, in order to describe it to you in a way that both makes you interested and also make you read them with the supposed expectations.
Sometimes, if not often, challenging questions are seemed to be negative criticism. When so, it can lead to defensive arguments and discussions more about points of view instead about facts. A tips is to make it clear from the beginning why the challenging questions and ideas are used.
"Where high in Stockholm" is based on one question and a city skyline like in Stockholm: I want to build around sixteen skyscrapers in Stockholm - where shall I build them?
"Why high speed trains?" I use this question as an example for some thoughts about more complex development situations.
