When you begin reading, you are already on a mission to find an answer. You follow along as the story unfolds, and when you've finished reading, you discover for yourself if the story is a tragedy, a comedy, or just a rewarding saga with a happy ending. The conclusion you reach is entirely dependant on your own skill and the writing efficacy of your narrator.
The howto is a unique sort of story, because in a howto, you, the reader, are the protagonist.
