[EX Q]: Question: Who won the $2,800 at the 1971 NASL tournament? Passage:The NASL first staged an indoor tournament in 1971 at the St. Louis Arena with a $2,800 purse. After a couple of years of experimenting, including a three-city tour by the Red Army team from Moscow in 1974, the league again staged tournaments in 1975 and 1976. For many years Tampa Bay owner George W. Strawbridge, Jr. lobbied his fellow owners to start up a winter indoor season, but was always stone-walled. For several years, his Rowdies and several other teams used winter indoor "friendlies" as part of their training and build-up to the outdoor season. In the meantime, pressed by the rival Major Indoor Soccer League (MISL), which inaugurated play in 1978, two-day mini-tournaments like the Skelly Invitational and the NASL Budweiser Invitational were held with varying degrees of success. The NASL finally started a full indoor league schedule, a 12-game season with 10 teams, in 197980. For the 198081 season, the number of teams playing indoor soccer increased to 19 and the schedule grew to 18 games. The schedule remained at 18 games, but the teams participating decreased to 13 for the 198182 season. The league canceled the 198283 indoor season and three teams (Chicago, Golden Bay, and San Diego) played in the MISL for that season. Four other teams (Fort Lauderdale, Montreal, Tampa Bay and Tulsa) competed in a short NASL Grand Prix of Indoor Soccer Tournament in early 1983. The NASL indoor season returned for 198384 with only seven teams but a 32-game schedule.

[EX Q]: 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 21 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 10. Next inning, Al Cowens's groundout with runners on second and third and no outs made it 20 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.

[EX Q]: Question: Of the diseases Alfred distinguished between, which lasts longer? Passage:Alfred Stille (October 30, 1813 September 24, 1900) was an American physician. Born in Philadelphia, he studied classics at Yale, but was expelled for participating in the Conic Sections Rebellion. He then transferred to the University of Pennsylvania in the same year, where he received an A.B. degree in 1832. He went on to get an A.M. from the University of Pennsylvania in 1835 and in 1836 an M.D. from the school's department of medicine. He settled to practice in his native city, but spent parts of 1841 and 1851 in Paris and Vienna. From 1854 to 1859 he was professor of medicine at the Pennsylvania Medical College and from 1864 to 1884 at the University of Pennsylvania, later becoming its Chair. Stille was one of the first in America to distinguish between typhus and typhoid fever. His observations in this connection he made during a typhus epidemic in Philadelphia in 1836 and reported in 1838. He acquired a great reputation as a practitioner, teacher, and writer, and was the first secretary, and in 187172 the president, of the American Medical Association. However, as evidenced by his later writings, he was also known for refusing to accept the germ theory or laboratory medicine.
