Input: Consider Input: Question: Who defeated Cartwright in the 1698 English general election? Passage:Cartwright served as High Sheriff of Northamptonshire in 1693. He was returned as Member of Parliament for Northamptonshire in an expensive contest at the 1695 English general election. Lord Charles Spencer was a Whig candidate, but fortunately his father Robert Spencer, 2nd Earl of Sunderland baulked at the required expenditure. Cartwright was then defeated at the 1698 English general election. He served as High Sheriff of Oxfordshire in 1699. He did not stand at the first general election of 1701 but in the second general election of 1701 he was returned after accepting a pact with Sir Justinian Isham, 4th Baronet that he had previously declined. He voted on 26 February 1702 for the resolution to vindicate the Commons’ proceedings in the impeaching the King’s ministers. He was returned again at the 1702 English general election but was absent from the House for some time because he had sprained his foot badly in a hunting accident. He was absent at the division on the Tack and was subsequently listed as a sneaker. At the 1705 English general election he was returned in a contest again with Isham. He voted against the Court candidate for Speaker. He was returned unopposed at the 1708 British general election but was not an active Member. He voted against the impeachment of Dr Sacheverell in 1710. He was returned unopposed again at the 1710 British general election and was listed as one of the ‘worthy patriots’ who approved the exposure of the previous ministry’s mismanagements, and as a ‘Tory patriot’ who voted for peace in 1711 . He also became a member of the October Club.

Input: Consider 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.
