  1. Use Prim's algorithm, starting from \(A\), to find the minimum spanning tree for the network.
  2. State the length of your minimum spanning tree.
  3. Draw your minimum spanning tree.
  4. A student used Kruskal's algorithm to find the same minimum spanning tree. Find the seventh and eighth edges that the student added to his spanning tree.
