Consider the following argument and say which sentence is a sub-conclusion (both a premise and a conclusion).

There is substantial evidence that Abner Doubleday did not invent baseball. He made no mention of it in his many letters and papers. He certainly would have mentioned the sport if he had invented it. Furthermore, the first recorded attribution of the sport’s invention to Doubleday—a 1908 commission report—claimed that Doubleday invented the sport in Cooperstown in 1839. However, he was enrolled at the U.S. Military Academy at West Point (>150 mi. trip) at that time and there is no evidence that he obtained leave. The current Major League Baseball commissioner, Bud Selig, believes that Doubleday did invent the game. Since there is evidence that Doubleday did not invent the sport and Bud Selig still believes that he did, Bud Selig is an idiot.
