Question: Which contemporary stadium in Portland and North Carolina that use Superblocks has the largest capacity? Passage 1:Superblocks are also used when functional units such as rail yards or shipyards, inherited from the 19th and early 20th centuries, are too big to fit in an average city block. A contemporary function which reflects ancient practices that also requires larger than typical blocks is the sports stadium or arena. Just as the Colosseum in ancient Rome, sports complexes require superblocks. The Providence Park stadium in Portland, for example, takes up four normal city blocks as does the equally large Greensboro Coliseum in North Carolina. Other contemporary institutions, establishments or functions that use superblocks are: city halls like Government Center, Boston and Toronto City Hall; regional general hospitals or specialized medical centres; convention and exhibition centers, such as Exhibition Place in Toronto and the Boston Convention and Exhibition Center; and downtown enclosed Shopping Malls such as Eaton Centre in Toronto, echoing the large gallerias of the 19th century. Cultural complexes, such as the Lincoln Center in New York City, often occupy a superblock achieved through the consolidation of regular city blocks. A recent superblock user is the merchandise distribution centre, which can range in area from one to ten city blocks.
 Passage 2:Rudd was probably born in North Yorkshire 1794 or 1795. He studied at St John's College, Cambridge where he got a B.A. before 1818 and a M.A. before 1821. He was ordained as deacon in 1818 and as priest in 1819 by John Fisher. He served as curate at Horsted Keynes (West Sussex) from 1818, at Shipton Bellinger (Hampshire) from 1819, and at Kimpton (Hampshire) from 1821. In 1833 he was appointed vicar of Sockburn (North Yorkshire), where he lived for a number of years at Worsall Hall near Yarm. His captures of beetles are mentioned by James Francis Stephens, John Curtis and Alexander Henry Haliday and he collected insects with George Samouelle. Rudd published six notes on insects in the Entomologist’s Magazine  and other journals between 1834 and 1846 some of which dealt with beetles. The last described Haltica dispar as a new species. (Zoologist, 4, 1846, p. 1517). He was a fellow of the Linnean Society and in 1833, he was a founder of the Entomological Society of London, later Royal Entomological Society. He died on 4 March 1847 in London at the age of 52.
 Passage 3:In the U.S., the northernmost is Martha's Diner in Coventry, Vermont. The Miss Wakefield, originally Pat & Bob's in Albany, New York, was built in 1949, rescued from a junkyard there, and trucked to a new home in Sanbornville, New Hampshire. The Summit Diner, a 1938 model, is located in Summit, New Jersey. The oldest Southern diner (non–stainless steel style) is believed to be the Hillsville Diner in Carroll County, Virginia. The Triangle Diner, a 1948 stainless steel O'Mahony original model, is located in the old town of Winchester, Virginia, and is being historically restored to how it appeared in 1948. The Triangle Diner is the oldest stainless steel style O'Mahony diner in Virginia. In 2007 Tommy's Deluxe Diner was moved from Middletown, Rhode Island, to Oakley, Utah, where it opened as the Road Island Diner. One of the original ones displayed at the 1939 New York World's Fair, made by Paramount Diners, is still in operation as the White Mana in Jersey City. Also in Jersey City is the Miss America, a 1942 classic stainless steel model, located next to the New Jersey City University campus. The Shawmut Diner of New Bedford, Massachusetts was donated by its owners to the Bristol County House of Corrections in Dartmouth, Massachusetts and will serve as a training facility for inmates. TJ's (formerly the Point Diner) in Tamaqua, Pennsylvania is a 1940 O’Mahony diner, although its exterior has been renovated and no longer has the stainless metal-look exterior. The diner is located within the Tamaqua Historic District.
