After earning a #1 seed in the East Region in the 2007 NCAA Tournament, Williams' team won its first-round game against Eastern Kentucky Colonels 8665 and its second against Michigan State 8167. North Carolina then defeated the USC Trojans 7464 to advance to the Elite Eight. On March 24, 2007, North Carolina fell to the Georgetown Hoyas in overtime in the East Regional, ending its post-season run.

Passage 2:The Best Science Fiction of the Year was a series of annual paperback anthologies edited by Terry Carr. It was published by Ballantine Books from 1972 to 1980, Pocket Books from 1981 to 1983, Baen Books in 1984, and Tor Books from 1985 to 1987. The Tor Books volumes bore the title Terry Carr's Best Science Fiction of the Year from 1985 to 1986, and Terry Carr's Best Science Fiction and Fantasy of the Year in 1987. Most volumes were also issued in hardcover in the United Kingdom by Gollancz, the last three under the variant title Best SF of the Year. The series was a continuation of the earlier anthology series World's Best Science Fiction, edited by Carr with Donald A. Wollheim, published from 1965 to 1971 by Ace Books. (Wollheim, with co-editor Arthur W. Saha, also issued his own separate continuation, The Annual World's Best SF, from 1972 to 1990.)
Passage 3:In 1839, Lin Zexu, who himself was a Fuzhou native, was appointed by the Daoguang Emperor to enforce the imperial ban on the opium trade in Canton. His unsuccessful actions, however, precipitated the disastrous First Opium War with Great Britain, and Lin, who had become a scapegoat for China's failure in war, was exiled to the northwestern section of the empire. The Treaty of Nanjing (1842), which put an end to the conflict, made Fuzhou (then known to Westerners as Foochow) one of five Chinese treaty ports, and it became completely open to Western merchants and missionaries. was one of the most important Protestant mission fields in China. On January 2, 1846, the first Protestant missionary, Rev. Stephen Johnson (missionary) from ABCFM (), entered the city and soon set up the first missionary station there. ABCFM was followed by the Methodist Episcopal Missionary Society that was led by Revs. M. C. White and J. D. Collins, who reached Fuzhou in early September 1847. The Church Missionary Society also arrived in the city in May 1850. These three Protestant agencies remained in Fuzhou until the communist revolution in China in the 1950s, leaving a rich heritage in Fuzhou's Protestant culture. They supported the creation of hospitals and schools, including the Woolston Memorial Hospital, run by the American-trained Hu King Eng.
