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.

Question: Who was older the year Dane appeared on Jackie Gleason's show, Otis Spann or Willie Dixon? Passage:By 1959, Louis Armstrong had asked Time magazine readers: "Did you get that chick? She's a gasser!" and invited her to appear with him on national television. She appeared with Armstrong on the Timex All-Star Jazz Show hosted by Jackie Gleason on January 7, 1959. She toured the East Coast with Jack Teagarden, appeared in Chicago with Art Hodes, Roosevelt Sykes, Little Brother Montgomery, Memphis Slim, Otis Spann, Willie Dixon and others, played New York with Wilbur De Paris and his band, and appeared on The Tonight Show Starring Johnny Carson as a solo guest artist. Other national TV work included The Steve Allen Show, Bobby Troup's Stars of Jazz, and Alfred Hitchcock Presents. In 1961, the singer opened her own club, Sugar Hill: Home of the Blues, on San Francisco's Broadway in the North Beach district, with the idea of creating a venue for the blues in a tourist district where a wider audience could hear it. There Dane performed regularly with her two most constant musical companions: Kenny "Good News" Whitson on piano and cornet and Wellman Braud, former Ellington bassist.

Question: For how many years did the man serve as President that swept all five boroughs of NYC in 1964? Passage:Roosevelt won his home state by means of a dominance of the massively populated New York City area, performing even more strongly than he had in 1932. Roosevelt took over seventy percent of the vote in the boroughs of Manhattan, Brooklyn, and the Bronx, and took over sixty percent of the vote in Queens and Staten Island. For the era, this was an historically overwhelming victory for a Democratic presidential candidate in the five boroughs of New York City, and enough to easily secure a statewide win for Roosevelt. The emergence of the New Deal Coalition was at its peak in 1936, and made American cities with their powerful political machines core bases of support for the Democratic Party. The Great Depression had accelerated the process of urbanization of the Democratic Party which had begun with the election of 1928. Roosevelt’s landslide win in New York City was a fruit born by this process, and over the whole nation he achieved majorities in the largest cities totalling twice what Harding had achieved in 1920. 1936 was the third election in a row in which Democrats had won all five boroughs of NYC, following 1928 and 1932. After 1936, New York City would remain Democratic overall in every election that has followed, although no presidential candidate would sweep all five boroughs of NYC again until Lyndon Johnson in 1964. Partly as a consequence of this, FDR’s 1936 victory in New York State would also be the strongest statewide Democratic performance ever in terms of both margin and vote share until 1964.
