"If you can’t get the client to provide any of these answers, I’d strongly suggest that you consider declining the project."

That's exactly what I was thinking as I read the list. I've dealt with projects where people either couldn't answer those, or couldn't be bothered to answer those questions. They're vital to the project and need to be answered by someone. Unsurprisingly, I (as the developer) rarely answer them correctly.

From my experience, I have found customers have a hard time answering some, if not most of these questions. Instead of rejecting the project because the customer cannot answer, I tend to provide detail to what each question is pointed at and provide a spectrum as an example.
