2. Give a complete problem formulation for each of the following. Choose a formulation that is precise enough to be implemented. A. Using only four colors, you have to color a planar map in such a way that no two adjacent regions have the same color. B. A 3-foot-tall monkey is in a room where some bananas are suspended from the 8-foot ceiling. He would like to get the bananas. The room contains two stackable, movable, climbable 3-foot-high crates. C. You have three jugs, measuring 12 gallons, 8 gallons, and 3 gallons, and a water faucet. You can fill the jugs up or empty them out from one to another or onto the ground. You need to measure out exactly one gallon.
