Example Input: Question: Who was the leader of the Porte in 1912? Passage:The modern Albanian-Serbian conflict has its roots in the expulsion of the Albanians in 1877-1878 from areas that became incorporated into the Principality of Serbia. Prior to the outbreak of the First Balkan War, the Albanian nation was fighting for a national state. At the end of 1912, the Porte recognised the autonomy of Albanian vilayet. These events for Albanian autonomy and Ottoman weakness were viewed at the time as directly threatening the Christian population of the region with extermination. The Balkan League (comprising Serbia, Montenegro, Greece and Bulgaria) jointly attacked the Ottoman Empire and during the next few months partitioned all Ottoman territory inhabited by Albanians. The Kingdom of Serbia and the Kingdom of Greece occupied most of the land of what is today Albania and other lands inhabited by Albanians on the Adriatic coast. Montenegro occupied a part of today's northern Albania around Shkodër. The Serbian army in the region viewed its role as protecting local Orthodox Christian communities and avenging the medieval battle of Kosovo, though it forced Catholic Albanians to convert to Orthodox Christianity.

Passage:The Prodigal Son is a best-selling novel by Hall Caine, published in November 1904 by Heinemann and translated into thirteen languages. It is set in a sheep-rearing community in rural Iceland, with scenes in London and the French Riviera. At the same time Caine adapted the novel into a play. The copyright performance was held at the Grand Theatre, Douglas, Isle of Man. American and British productions opened days apart in 1905, at the National Theatre in Washington, D. C. on 28 August, the New Amsterdam Theatre in New York City on 4 September and at the Theatre Royal, Drury Lane, London on 7 September, with George Alexander playing Oscar and Caine's sister Lilian playing Thora. After a long run at Drury Lane it was revived in 1907. In The Prodigal Son Magnus learns on his wedding day that his bride, Thora, is in love with his brother Oscar, a composer. She marries Oscar after Magnus releases her from the engagement. When Thora dies, a distraught Oscar places the only copies of his compositions in her coffin. Later he has her grave opened and his music retrieved. It was filmed in 1923. A.E. Coleby's 18,454 feet, nineteen reel film The Prodigal Son became the longest commercially made British film.
