Question: Who produced the ABC police dram in which Vidal was a series regular? Passage 1:Ronnie Barker and Ronnie Corbett met in 1963 at the Buckstone Club in the Haymarket, London, where Corbett was serving drinks between acting jobs. At the time, Barker was beginning to establish himself as a character actor in the West End and on radio. They were invited by David Frost to appear in his new show, The Frost Report, with John Cleese, but the pair's big break came when they filled in, unprepared and unscripted, for eleven minutes during a technical hitch at a British Academy of Film and Television Arts awards ceremony at the London Palladium in 1970. In the audience was Bill Cotton, the Head of Light Entertainment for the BBC, and Sir Paul Fox, the Controller of BBC1. Cotton was so impressed by the duo that he turned to Fox and asked: "How would you like those two on your network?" Unbeknownst to them the pair had just had the renewal of their contract declined by London Weekend Television of rival network ITV, and so were free to change channels. Barker and Corbett were given their own show by the BBC.
 Passage 2:Vidal was series regular in the ABC police drama High Incident (1995–1996), and on The Brian Benben Show in 1998, and later had major recurring roles on Third Watch from 1999–2001 as Dr. Sarah Morales, and ER from 2001–2004 as firefighter Sandy Lopez. From 2001 to 2004, Vidal starred opposite Bonnie Bedelia in the Lifetime drama series The Division, for which she received the 2002 nomination for the ALMA Award in the Best Actress Category. In 2006, she had a brief role in the short-lived action series Smith, as one of the federal agents looking for Ray Liotta's group of thieves. In 2010 she starred in NBC drama The Event.
 Passage 3:The Pakistan Muslim League (; known as PML), is the name of several different Pakistani political parties that have dominated the Right-wing platform since the 1960s. The first "Pakistan" Muslim League was founded by President Ayub Khan in 1962 as a successor to the original Muslim League. Just a short period after its foundation, the party broke into two factions: Convention Muslim League that supported the President and the new Constitution, and the Council Muslim League, that opposed the new Constitution, denouncing it as undemocratic that made the Presidency an autocratic position. Following President Ayub's resignation, Nurul Amin, a right-wing political veteran, attempted to reunite the factions of Pakistan Muslim League. His efforts were supported by some, while opposed by others. Before the 1970 Elections, a senior leader of Council Muslim League, Abdul Qayyum Khan formed his own variant of the Muslim League that opposed cooperation with a party that once supported a Dictator. In 1973, Amin's efforts succeeded and the Functional Muslim League (PML-F) was founded.
