Example Input: The film is a postmodern spoof that tells the story of Zeus' modern day illegitimate children, Filmore (Tony Griffin) and his half-sister Marie-Noel (Alison Elliott), who are forced to move from their Channel Island ranch because their neighbors have grown suspicious of the fact they haven't aged for decades. Meanwhile, the U.S. government wants to turn their land into a national park. When the twelve Greek Gods return to Los Angeles for relaxation Zeus expects them to correctly identify the play fated and modeled around their current lives—Oscar Wilde's The Importance of Being Earnest—and perform the work flawlessly, in its entirety, for the Gods' entertainment. By such means, as the play's plot unfolds, the children are guaranteed new, credible lives. "Act or die," he commands. But if they fail to perform the play to its conclusion, or if they rebel, they will be killed by jealous Hera. The mere existence of these illegitimate children are an outrage to her, representing Zeus' countless infidelities. 12—whose title is often mistakenly derived from the number of years it took to create the film (10 actually)—is described by Variety as "equal parts L.A. love story, The Importance of Being Earnest, spoof on Greek gods and personal diary of actual events from 1988 to 1998." The director used more than 500,000 feet (150,000 m) of film. 
Question: Filmore is accompanied by what kind of siblin in his journey?
Example Output: His half sister Marie

Example Input: In January 1918, Romanian forces established control over Bessarabia as the Russian Army abandoned the province. Although a treaty was signed by the Romanian and Bolshevik Russian governments following talks between 5 and 9 March 1918 on the withdrawal of Romanian forces from Bessarabia within two months, on 27 March 1918 Romania formally attached Bessarabia to its territory, based on a resolution passed by the local assembly of that territory on its unification with Romania. Romania officially made peace with the Central Powers by signing the Treaty of Bucharest on 7 May 1918. Under the treaty, Romania was obliged to end the war with the Central Powers and make small territorial concessions to Austria-Hungary, ceding control of some passes in the Carpathian Mountains, and to grant oil concessions to Germany. In exchange, the Central Powers recognised the sovereignty of Romania over Bessarabia. The treaty was renounced in October 1918 by the Alexandru Marghiloman government, and Romania nominally re-entered the war on 10 November 1918. The next day, the Treaty of Bucharest was nullified by the terms of the Armistice of Compiègne. Total Romanian deaths from 1914 to 1918, military and civilian, within contemporary borders, were estimated at 748,000. 
Question: Who granted oil concessions to Germany?
Example Output:
Romania
