[EX Q]: Passage: Jordan played three seasons for coach Dean Smith at the North Carolina Tar Heels mens basketball. As a freshman, he was a member of the 1981–82 North Carolina Tar Heels mens basketball team in 1982 NCAA Division I Mens Basketball Tournament. Jordan joined the Bulls in 1984–85 NBA season as the 1984 NBA draft draft (sports) pick. He quickly emerged as a league star and entertained crowds with his prolific scoring. His leaping ability, demonstrated by performing slam dunks from the free throw line in Slam Dunk Contests, earned him the nicknames Air Jordan and His Airness. He also gained a reputation for being one of the best defensive players in basketball. In 1991 NBA Finals, he won his first NBA championship with the Bulls, and followed that achievement with titles in 1992 NBA Finals and 1993 NBA Finals, securing a "three-peat". Although Jordan abruptly retired from basketball before the beginning of the 1993–94 NBA season, and started a new career in Minor League Baseball, he returned to the Bulls in 1994–95 NBA season and led them to three additional championships in 1996 NBA Finals, 1997 NBA Finals, and 1998 NBA Finals, as well as a then-record List of NBA teams by single season win percentage in the 1995–96 NBA season. Jordan retired for a second time in 1998–99 NBA season, but returned for two more NBA seasons from 2001 to 2003 as a member of the Wizards.

[EX Q]: Passage: In 1877 the price of British-grown wheat averaged 56 shillings and 9 pence a quarter and for the rest of the nineteenth century it never reached within 10 shillings of that figure. In 1878 the price fell to 46 shillings and 5 pence. In 1886 the wheat price decreased to 31 shillings a quarter. By 1885 wheat-growing land declined by a million acres (4,000 km²) (28½%) and the barley area had dwindled greatly also.  Britains dependence on imported grain during the 1830s was 2%; during the 1860s it was 24%; during the 1880s it was 45%, (for wheat alone during the 1880s it was 65%.) The 1881 Census in the United Kingdom showed a decline of 92,250 in agricultural labourers in the ten years since 1871, with an increase of 53,496 urban labourers. Many of these had previously been farm workers who migrated to the cities to find employment, despite agricultural labourers wages being higher than those of Europe. Agricultures contribution to the national income was about 17% in 1871; by 1911 it was less than 7%.
Question: How many percent did agriculture's contribution to the national income change between 1871 and 1911?
[EX A]:
