question:
Question: Which city was larger the year Cowan was born, Braeholm or Los Angeles? Passage:Charles Edward Cowan (June 19, 1938 in Braeholm, West Virginia April 29, 1998 in Los Angeles, California) was an American football offensive tackle who played fifteen seasons in the National Football League with the Los Angeles Rams from 1961 to 1975. Cowan was a huge intimidating presence on the left of Tom Mack, a member of the Pro Football Hall of Fame, from 1966 to 1975, forming a potent left side of the offensive line, with help from Ken Iman at center from 1965 to 1975. In that 1961 to 1975 span, the Rams made the playoffs 5 times (1967,1969,1973,1974,1975), reaching the NFC championship game of the 1974-75 NFL playoffs and the 1975-76 NFL playoffs, but losing to the Minnesota Vikings and to the Dallas Cowboys, respectively. In the 1974 divisional round, the Rams defeated the Washington Redskins, as Cowan was successful against the opposing the right defensive end Verlon Biggs. In the 1975 divisional round, Doug France started in his place as the Rams defeated the St. Louis Cardinals. Cowan came back to play against the Cowboys, his final game, as the Rams could not get past them. Cowan was replaced by Doug France in 1976.

question:
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:
Question: What was John Holt's career? Passage:Youth activism as a social phenomenon in the United States truly became defined in the mid- to late-nineteenth century when young people began forming labor strikes in response to their working conditions, wages, and hours. Mary Harris "Mother" Jones organized the first youth activism in the U.S., marching 100,000 child miners from the coal mines of Pennsylvania to the U.S. Capitol in Washington, D.C. in 1908. Youth newspaper carriers soon followed. These actions isolated youths' interests in the popular media of the times, and separated young people from their contemporary adult labor counterparts. This separation continued through the 1930s, when the American Youth Congress presented a "Bill of Youth Rights" to the US Congress. Their actions were indicative of a growing student movement present throughout the US from the 1920s through the early 1940s. The 1950s saw the Student Nonviolent Coordinating Committee bring young people into larger movements for civil rights. All the way back in 1959, Rev. Dr. Martin Luther King, Jr. engaged youth activists in protesting against Bull Connor's racist law enforcement practices in Birmingham, Alabama. The youth activism of Tom Hayden, Keith Hefner and other 1960s youth laid a powerful precedent for modern youth activism. John Holt, Myles Horton and Paulo Freire were important in this period. Youthful life and expression defined this era.
