Example Input: 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.

Example Input: Question: How old was Jovan Rajić when he became a priest in Kovilj? Passage:The present, stone church, was built from 1741 to 1749 by the neimars (builders) Teodor Kosta and Nikola Krapić. It was built in the Morava architectural school style of Serbo-Byzantine architecture and patterned after Manasija and Ravanica. In 1758, Empress Maria Theresa issued a document which set the monastery's estate. By the imperial privilege, the land was strictly divided between the monastery and the nearby settlement of Koviljski Šanac. The establishment of the Šajkaš Battalion in 1763, Serbian settlements surrounding the monastery were repopulated and preserved, which also influenced the prosperity of the monastery. Forerunner of the modern Serbian historiography, Jovan Rajić, became a priest in Kovilj and was appointed the archimandrite of the monastery in 1772, where he died in 1801. During the Hungarian Revolution of 1848, the rebels used the monastery as their base in 1849 which forced the monks to move across the Danube, into the Syrmia region. When they returned after the collapse of the rebellion, the monastery was looted and burned, and many historical treasures have been lost. The new church damaged inside while the old one was almost completely ruined, so it was demolished in 1850. Since 1850, the monks began to collect funds for the restoration. Some of it was secured by the Austrian state, some by the donations of the population and some was help from Russia. Young painter Aksentije Marodić has painted the new iconostas in the 1880s, including the scenes from the life of Christ and replicas of the most famous paintings from that period which Marodić copied from the galleries in Vienna, Munich, Paris, Rome, Venice, and Naples. The walls themselves are not painted. Woodworks and carvings are work of Jovan Kisner, while the gold plating and marble work were done by Ludvig Tauš. The work on the interior turned out to be quite lengthy, as it lasted until 1891/92.
