Example Input: Question: Did Brett or Mayberry start playing professional baseball first? Passage:At Kauffman Stadium, Dennis Leonard pitched a four-hit complete game to give the Royals a 2–1 series lead. After a one-out walk and single, Freddie Patek's RBI single off of Mike Torrez in the second put the Royas up 1–0. Next inning, Al Cowens's groundout with runners on second and third and no outs made it 2–0 Royals. The Yankees got on the board in the fifth when Graig Nettles singled with two outs and scored on Lou Pinella's double, but the Royals got that run back in the bottom of the inning when Hal McRae hit a leadoff double, moved to third on a groundout, and scored on Cowens's groundout. Next inning, Torrez allowed a leadoff walk and single, then got two outs before being relieved by Sparky Lyle, who allowed a two-run double to Amos Otis. Next inning, George Brett hit a leadoff single and scored on John Mayberry's RBI double. The Yankees got a run in the ninth when Roy White doubled with one out and scored on first baseman Mayberry's error on Reggie Jackson's ground ball before Chris Chambliss grounded out to end the game.

Passage:The Last Detail was nominated for the Palme d'Or at the 1974 Cannes Film Festival and Nicholson was awarded Best Actor. It was also nominated for three Academy Awards – Jack Nicholson for Best Actor in a Leading Role, Randy Quaid for Best Actor in a Supporting Role, and Robert Towne for Best Writing, Screenplay Based on Material from Another Medium with none of them winning. In addition, The Last Detail was nominated for two Golden Globes Awards – Nicholson for Best Motion Picture Actor – Drama and Quaid for Best Supporting Actor – Motion Picture. Nicholson did win a BAFTA award for his role in the film. Nicholson won the Best Actor awards from the National Society of Film Critics and the New York Film Critics Circle. However, he was disappointed that he failed to win an Oscar for his performance. "I like the idea of winning at Cannes with The Last Detail, but not getting our own Academy Award hurt real bad. I did it in that movie, that was my best role".
