[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: How many albums did the band that had Cedric Bixler-Zavala as a frontman release? Passage:At the Drive-In frontman Cedric Bixler-Zavala stated that "there would be no Relationship of Command without Drive Like Jehu." He declared: "I remember doing a lot of English press and people being like, 'We think you guys are exotic, the names of the songs and flannel and look is exotic.' I definitely knew what school we came from, and that people like Hot Snakes and Drive Like Jehu were our strongest influences, but they weren't exactly huge in Europe." Isaac Brock of the indie rock band Modest Mouse said in 2007: "I love [Drive Like] Jehu. Jehu is one of my favorite all-time bands actually." Deftones covered their song "Caress" on their 2011 cover album. Brian Cook, bassist for the metalcore band Botch, stated that "Drive Like Jehu was a huge influence on Botch; their writing approach definitely mirrored what we did in terms of banging things out till we had a song." British hardcore punk group Gallows were also inspired by them and Laurent Barnard singled out John Reis as one of his five favorite guitarists. The Blood Brothers vocalist Jordan Blilie described Rick Froberg's lyrics in the band as "equal parts perplexing and relatable" and called his voice "one of my all-time favorites". He added that the early guitar playing of his own group can be mostly traced back to Jehu. Other artists who have cited them as an influence or expressed admiration for their work are Thursday, Jim Adkins of Jimmy Eat World, Justin Pearson of The Locust, Ben Weinman of The Dillinger Escape Plan, Violent Soho, Unbroken, Akimbo and Sandrider, KEN Mode, METZ, Matthew Bajda of Funeral Diner, Bryan Giles of Red Fang, Steven Roche of Off Minor and Genghis Tron.
