Why?
Should you buy a used car with the best gas mileage, the lowest mileage, or the fewest owners? Should you invest in a backpacking tent that is the lightest, the most durable, or the most waterproof? What about computer models? Three-dimensional computer models require three variables to account for length, width, and height of figures. In the real world, many problems have three or more factors to consider to find the best available option.
