Q: Question: How long had Nawaz Sharif been in power as the Prime Minister when he acknowledged his country's nuclear capabilities? Passage:After the Soviet withdrawal from Afghanistan, the rivalry between Iran and Pakistan intensified. After 1989, both state's policies in Afghanistan became even more divergent as Pakistan, under Benazir Bhutto, explicitly supported Taliban forces in Afghanistan. This resulted in a major breach, with Iran becoming closer to India. Pakistan's support for the Sunni Taliban organisation in Afghanistan became a problem for Shia Iran which opposed a Taliban-controlled Afghanistan. The Pakistani backed Taliban fought the Iranian backed Northern Alliance in Afghanistan and gained control of 90 percent of that country. As noted by a Pakistani foreign service officer, it was difficult to maintain good relations with Israel, Saudi Arabia, the United States, and Iran at the same time, given Iran's long history of rivalry with these states. In 1995 Bhutto paid a lengthy state visit to Iran, which greatly relaxed relations. At a public meeting she spoke highly of Iran and Iranian society. However, increasing activity by Shia militants in Pakistan strained relations further. This was followed by the Taliban's capture of the city of Mazar-i-Sharif in 1998, in which thousands of Shias were massacred, according to Amnesty International. The most serious breach in relations came in 1998, after Iran accused Taliban Afghanistan of taking 11 Iranian diplomats, 35 Iranian truck drivers and an Iranian journalist hostage, and later killing them all. Iran massed over 300,000 troops on the Afghan border and threatened to attack the Taliban government, which it had never recognized. This strained relations with Pakistan, as the Taliban were seen as Pakistan's key allies. In May 1998, Iran criticised Pakistan for its nuclear testing in the Chagai region, and held Pakistan accountable for global "atomic proliferation". New Prime Minister Nawaz Sharif acknowledged his country's nuclear capability on 7 September 1997.

Q: Question: Which North American city hall building that used Superblocks was completed first? Passage: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.

Q: Question: What is the main characteristic of the type of architecture that was gilded at St Michael's Church? Passage:The roof of the nave is painted red and is divided into squares by ribs, at whose intersections are gilded bosses of different designs. The font is located halfway down the north side of the nave. It is Victorian and consists of an octagonal gabled and crocketted bowl on an octagonal column. The wooden pulpit is massive, measuring approximately from the base to the top. To the east of the south door are churchwardens' box pews carved with Gothic details and poppyheads. They bear a brass plate dated 1770. In the nave are monuments to the memory of the Cliftons of Lytham Hall, including one to Thomas Clifton who died in 1688. A wall tablet commemorates Richard Bradkirk of Bryning Hall who died in 1813 and another monument is to Henry Rishton Buck, a lieutenant aged 27 who died at the Battle of Waterloo. Behind the altar is a folding reredos dated 1900 which was made by Kempe and moved from Christ Church Cathedral, Oxford. The brass chandelier dated 1725 was made by Brown of Wigan. The organ dates back to 1769 when it was built by Glyn Parker of Salford. Later modifications were made by R. W. Nicholson of Bradford (at an unrecorded date), by Harrison & Harrison in 1905, and by the Pendlebury Organ Company of Cleveleys in 1979. There is a ring of eight bells which were cast by Charles & George Mears at the Whitechapel Bell Foundry in 1846.
