Read this part of Gabriel Garcia Marquez's "One of These Days." "'[The mayor] says if you don't take out his tooth, he'll shoot you.' Without hurrying, with an extremely tranquil movement, [the dentist] stopped pedaling the drill, pushed it away from the chair, and pulled the lower drawer of the table all the way out. There was a revolver. 'O.K.,' he said. 'Tell him to come and shoot me.'" This part best represents which form of conflict?
