Answer: The passage provided has been organized by order of importance.
Step-by-step explanation: The passage belonging to a cause-and-effect essay has been organized in terms of order of importance. In this case, the causes and effects have been ordered from the least important to the most important. In that way, the last sentence presents the most important cause: "the date is essential for tracking and paying bills". Without this date, the check for the bill, which represents the effect, cannot be issued.
