I prefer Question, questions brings more curiosity and research into a concept, while answers are just one way and might be boring, questions posed in individual different answers, you can see this too on Steemit Post, if a user has written everything and put the questions and the answers there, the reader finds it hard to comments or connect and so on. But if a question is posed out, trust me, you'll have so many answers coming from so many angles and Perspective.
The beginning is very crucial in life, so also is anything I like to get involved in, I always wants to search how it begins, the beginning is an opening to multiple ending while the ending is an end of itself. If you don't know how something begins trust me, to find a solution to it will be hard.
Agreed, questions can lead to discussion and engagement. With a complete answer, there is difficulty in continuing the conversation unless you know the topic in detail and can ask relevant questions again! I've been really happy with all the answers that I get from people from different experiences and backgrounds!
Also agree very much with your sentiment on the beginning, without one, there is no ending!
