Question: Which of the cities that Thomas Onslow stood for Parliament for had the largest population? Passage 1:Amaseia was captured by the Roman Lucullus in 70 BC from Armenia and was quickly made a free city and administrative center of his new province of Bithynia and Pontus by Pompey. By this time, Amaseia was a thriving city, the home of thinkers, writers and poets, and one of them, Strabo, left a full description of Amaseia as it was between 60 BC and 19 AD. Around 2 or 3 BC, it was incorporated into the Roman province of Galatia, in the district of Pontus Galaticus. Around the year 112, the emperor Trajan designated it a part of the province of Cappadocia. Later in the 2nd century it gained the titles 'metropolis' and 'first city'. After the division of the Roman Empire by emperor Diocletian the city became part of the East Roman Empire (the Byzantine Empire). At this time it had a predominantly Greek-speaking population.
 Passage 2:Vallow then went on to Sony to produce their first primetime series, Dilbert, with Larry Charles, which ran on UPN for two seasons. She then took over as producer for season three of Family Guy before its brief cancellation. In 2004, Vallow created and produced the animation sequences in the critically acclaimed and award-winning documentary In the Realms of the Unreal directed by Jessica Yu. She produced the MTV series 3 South, the pilot for Comedy Central’s Drawn Together and the presentations for Fox’s American Dad! and an untitled Phil Hendrie pilot, before Fox made the decision to bring back Family Guy for an unprecedented 35 episode order. In order to accommodate producing both Family Guy and American Dad! simultaneously, she built a standalone animation studio for 20th Television and assembled a 200+ person team. She also produced the Fox presentations Two Dreadful Children and Bordertown. Nominated for five Emmys, Vallow was at one time responsible for three half-hours of programming on Sunday nights: Family Guy, American Dad!, and The Cleveland Show.
 Passage 3:The first known appointment to the position was that of Denzil Onslow in 1686 or 1694. He was deprived of his office in 1711 when the Junto Whigs were crushed. In 1715, the office was granted to Denzil's great-nephew Hon. Thomas Onslow. While it provided an emolument for him, the principal purpose of the appointment was to force Thomas to vacate his seat as Member of Parliament for Guildford, under the terms of the Place Act 1707. By removing him from the House of Commons, he could now stand in the by-election for Surrey, which had been vacated when his father Richard was made a Teller of the Exchequer. (Richard was about to be made a peer, hence his failure to stand in the by-election himself.) Two years later, when Thomas succeeded to his father's barony, Denzil Onslow again received the office for the same reason, vacating his seat at Guildford to successfully contest Surrey. This presaged the use of other offices of profit under the Crown as a means of resignation from the British House of Commons, which became formalised in the offices of Steward of the Chiltern Hundreds and Steward of Northstead.
