The graph below shows the roads in a rural county in your state. All the roads are gravel, but the county plans to pave certain roads to make travel easier. They want to pave only enough roads so that people can travel from each town to any other town on paved roads, even if they can't always take the shortest route. The value on each edge shows the cost of paving that road in $10,000 units. Which roads would you choose to pave to keep the cost as low as possible? Explain your answer. 8 10 B D 12 10 8 E 8
