In the capital of the grand country of Appelhaken there is a plane garden containing four magnificent monuments. So magnificent are they that the country has a Law requiring that there must be a clearly marked carpeted path all the way from each monument in the garden to each other monument, and no two such paths may share parts or intersect.
A fifth monument is installed. In order to comply with the Law, the best architect in all of Appelhaken designs a grand and magnificent bridge in the garden, and one path is laid on top of the bridge while another is laid underneath it, for without this bridge the Law could not be upheld.
Shortly afterwards, two more monuments are installed, but there is no more money for additional bridges because the first bridge was too grand. How can the chief gardener of Appelhaken reroute paths to preserve the Law?
The bridge might need to be used for several paths.
