   Serial  Prefixes  --- chain of  length- 4   
      
                    Find a 3-letter   [Prefix String]   for each word in the   
   group to make a new, compound word.   
      
                    The 3-letter Prefix has one-letter changed from the previous   
   group   ------------ (Example:     Group 1 = Run, Group 2 = Fun, Group 3 = Sun)
