1. Which vertex plays the role of v in Kempe's false proof?
2. Make a one-to-one correspondence between the colors of v's neighbors in Figure 13.22 and the numbering of colors used in our version of Kempe's false proof.

3. Identify the different Kempe chains emanating from neighbors of v. Which chains play the roles of the color-1-color-4 Kempe chain and the color-2- color-4 Kempe chain in Kempe's false proof?
