The problem is that the answer, for a given question, in any reasonably complex solution space, is entirely dependent on the very local problem space that you're forcing them to guess where it is in a much larger problem space area. If you're asking someone that's familiar with the broader view of each, they're probably asking because their guess of where you are is close to some "trivial" type solution. Or, they have a bunch of answers that depends on what you're doing, and you're forcing them to guess.

The goal is very clear in your head. The way to achieve that might be a web of possibilities. You asking suggests they can see the web and you can't.
