explanation: "business" requires "taxation", and once "business" is "taxed". "borrowing books" requires "returning", and once "borrowing books", it will be "returned". "voting" is a way of "rating". a "ball game" involves the "sports" of the ball. "registration" and "checking in" have no obvious logical relationship.
