Four towns are arranged at the corners of a square, and we need to figure out the most efficient road network that connects all four without covering too much unnecessary asphalt.
One incorrect approach is the O-loop, which relies too heavily on redundant roads. Another option, the U-route, is also considered overambitious.
The X-road is often touted as a solution because it provides the shortest path between any two points, but it's not the optimal answer when considering the overall length of road.
We're invited to take an alternative approach: try to visualize the solution using soap bubbles or attempt to make a mental connection with a familiar real-world shape.
