Example Input: Passage: Both Alsatian and Standard German were for a time banned from public life (including street and city names, official administration, and educational system). Though the ban has long been lifted and street signs today are often bilingual, Alsace-Lorraine is today very French in language and culture. Few young people speak Alsatian today, although there do still exist one or two enclaves in the Sundgau region where some older inhabitants cannot speak French, and where Alsatian is still used as the mother tongue. A related Alemannic German survives on the opposite bank of the Rhine, in Baden, and especially in Switzerland. However, while French is the major language of the region, the Alsatian dialect of French is heavily influenced by German and other languages such a Yiddish in phonology and vocabulary. Question: Although Aslation is rarely used today, which region still uses their mother language of Aslation?
Example Output: Sundgau region

Example Input: Passage: In New York City in 1846, Alexander Turney Stewart established the "Marble Palace" on Broadway, between Chambers and Reade streets. He offered European retail merchandise at fixed prices on a variety of dry goods, and advertised a policy of providing "free entrance" to all potential customers. Though it was clad in white marble to look like a Renaissance palazzo, the building's cast iron construction permitted large plate glass windows that permitted major seasonal displays, especially in the Christmas shopping season. In 1862, Stewart built a new store on a full city block with eight floors and nineteen departments of dress goods and furnishing materials, carpets, glass and china, toys and sports equipment, ranged around a central glass-covered court. His innovations included buying from manufacturers for cash and in large quantities, keeping his markup small and prices low, truthful presentation of merchandise, the one-price policy (so there was no haggling), simple merchandise returns and cash refund policy, selling for cash and not credit, buyers who searched worldwide for quality merchandise, departmentalization, vertical and horizontal integration, volume sales, and free services for customers such as waiting rooms and free delivery of purchases. His innovations were quickly copied by other department stores. Question: What policy did the Marble Palace introduce? 
Example Output: "free entrance" to all potential customers.

Example Input: Passage: After the financial crisis of 2007–08, it was known in 2008–2009 that two Portuguese banks (Banco Português de Negócios (BPN) and Banco Privado Português (BPP)) had been accumulating losses for years due to bad investments, embezzlement and accounting fraud. The case of BPN was particularly serious because of its size, market share, and the political implications - Portugal's then current President, Cavaco Silva, and some of his political allies, maintained personal and business relationships with the bank and its CEO, who was eventually charged and arrested for fraud and other crimes. In the grounds of avoiding a potentially serious financial crisis in the Portuguese economy, the Portuguese government decided to give them a bailout, eventually at a future loss to taxpayers and to the Portuguese people in general. Question: On what charge was BPN's CEO arrested?
Example Output:
fraud
