Example Input: Question: Who is the current leader of the party Hartley began leading in 1919? Passage:He was born in St. Johns, Canada East. The son of Edward Hartley Dewart, a Methodist minister who was a staunch advocate of prohibition, the younger Dewart inherited his Liberal politics but broke with his father on the temperance issue becoming a firm opponent of prohibition, a move that would cost him dearly later in life. He studied at the University of Toronto and Osgoode Hall and was called to the Ontario bar in 1887. Dewart set up practice in Toronto and served as crown attorney for York County from 1891 to 1904. He was first elected to the provincial legislature in a 1916 by-election after the death of James Joseph Foy in the Toronto Southwest electoral district, becoming the first Liberal to win a Toronto seat in a quarter century. In 1919, he became leader of the Ontario Liberal Party. He resigned as leader in 1921 due to opposition within his caucus to his anti-prohibitionist stance. He returned to private practice and died at his home near Uxbridge in 1924.

Example Input: Question: When was the school where Mustafa studied law founded? Passage:Golubić completed his primary education in Stolac, before relocating to Sarajevo to attend high school. In 1908, he moved to Belgrade for post-secondary studies, studying law at the University of Belgrade. Some of Golubić's classmates and contemporaries later recounted that Golubić was recruited by the Russian secret police, the Okhrana, in his youth. The historian Vladimir Dedijer later consulted the records of the Hoover Institution in an attempt to verify this claim, to no avail. Golubić did join Young Bosnia (), a multi-ethnic youth organization agitating for the separation of Bosnia and Herzegovina from Austria-Hungary. The organization's membership was around 70 percent Serb, 20 percent Bosnian Muslim and 10 percent Croat. Following the outbreak of the Balkan Wars in November 1912, Golubić joined the volunteer Chetnik detachment of Major Vojislav Tankosić. As part of their training, Tankosić ordered that Golubić and the other volunteers jump into the Sava from a railway bridge, "just to see whether you are going to fulfill all my orders."
