It's a great list of questions, but don't take the translations too literally. Usually when VCs ask "what's your exit strategy" they're just checking to see whether you've been thinking about, not looking to take you out as CEO. If you go into every conversation expecting the person you're talking with to be evil, it will really warp your experience.
Need is infinite. All markets already exist and successful start ups just create products and services that capitalize on novel approaches to old problems. There are no blue oceans.
"1. Where did you get your idea? Translation: if your simple idea is so great, why hasn’t anyone else done it?"
I assume every idea I think up has already been thought of, in fact, I'm almost certain they have been. A better question to ask would be "How are you going to successfully execute your idea?"
