Input: Question: What is the population of the town where Gawler established his own firm? Passage 1:Maryanoff has been active in the fields of medicinal chemistry and organic chemistry. He is an inventor of topiramate, a unique sugar sulfamate drug, which has been marketed worldwide for the treatment of epilepsy and migraine, attaining annual sales of more than $2 billion. Topiramate is also a principal component of the antiobesity drug Qsymia. Maryanoff is an internationally renowned expert in drug design and drug discovery, especially in the application of protein structure-based drug design. He made seminal contributions to understanding the stereochemistry and mechanism of the Wittig reaction; adapted the cobalt-catalyzed alkyne trimerization to the synthesis of macrocycles; and devised novel peptides that undergo self-assembly to mimic native collagen structurally and functionally. Maryanoff is an author on 280 scientific publications, including several books (editor), book chapters, and review articles. He is an inventor on 100 issued U.S. patents, has presented over 185 invited lectures worldwide, and mentored 11 postdoctoral associates. Maryanoff organized and edited a special memorial issue of the Journal of Medicinal Chemistry to honor the memory of Dr. Paul Janssen (2005) and has served on numerous editorial advisory boards for scientific journals and research grant review committees.
 Passage 2:Gawler was born in Adelaide, South Australia, to Caroline (née Philpot) and Henry Gawler. His grandfather, George Gawler, was the second Governor of South Australia. Gawler attended St Peter's College, Adelaide, and then studied law at the University of Adelaide. Gawler was called to the bar in South Australia in 1886, and left for Western Australia later that year, establishing his own firm in Perth. At one time, he was in partnership with Robert Bruce Burnside, a future Supreme Court justice. Having previously served on the Peppermint Grove Road Board for a period, Gawler was elected to parliament at a 1910 Legislative Council by-election, which had been caused by the resignation of Walter Kingsmill. He died in office in May 1915 (aged 54), of typhoid fever. He had married Eva Mary Waldeck in 1893, with whom he had four children.
 Passage 3:Benfica's first competitive game was an away Primeira Liga opener against Rio Ave. Sánchez Flores did not have Reyes, and Jonathan Urretaviscaya started instead. At the Estádio dos Arcos, the home team scored first with a 55th-minute goal from José Semedo. A minute later Benfica evened the score, with Urreta assisting Nuno Gomes for the 1–1 final result. It was the fourth consecutive time that Benfica failed to win their league start. Sánchez Flores said that Rio Ave created unexpected problems: "It was not a easy game. We had a quality opponent, who left us trailing when we were not expecting it." During the last week of August Benfica brought in Honduran striker David Suazo on loan, sold right-back Nélson Marcos to Betis and was paired with Italian side Napoli in the UEFA Cup first-round draw on 29 August. A day later, Benfica hosted Porto for the first Clássico of the season. The visitors started better, converting a 10th-minute penalty kick for a Kostas Katsouranis foul against Lucho González. In the 56th minute, Cardozo exploited a mistake by Helton to head in the equaliser. Three minutes later Katsouranis was sent off, but Benfica held the tie until the final whistle. Quique Flores said, "It was a good game. In normal conditions we would have done better, but circumstances made it a little harder."
