One of the following statements about contouring is not true. Which statement is FALSE?

• One interpolates between given values to correctly place an isopleth

• Lines should be labeled on each end, and in the middle if it's a long line

• Contour lines never cross each other, and the final product should be smooth lines

• Contour lines never branch or fork, but extrapolation for data void regions is permissible

• A good strategy is to find local maximums and minimums first, and start drawing around one of these.
