Task: Question Generation
Input (English): Professional wrestling in the U.S. tends to have a heavy focus on story building and the establishment of characters (and their personalities). There is a story for each match, and even a longer story for successive matches. The stories usually contain characters like faces and heels, and less often antiheroes and tweeners. It is a "triumph" if the face wins, while it is a "tragedy" if the heel wins. The characters usually have strong and sharp personalities, with examples like Doink the Clown, whose personality is melodramatic, slapstick and fantastical. The opposition between faces and heels is very intense in the story, and the heels may even attack the faces during TV interviews. The relationship between different characters can also be very complex.
Output (English): Who is usually included in stories?
