Input: Consider 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?

Output: "free entrance" to all potential customers.

Input: Consider Input: Passage: The record transfer fee for a Premier League player has risen steadily over the lifetime of the competition. Prior to the start of the first Premier League season Alan Shearer became the first British player to command a transfer fee of more than 3 million. The record rose steadily in the Premier League's first few seasons, until Alan Shearer made a record breaking 15 million move to Newcastle United in 1996. The three highest transfer in the sport's history had a Premier League club on the selling end, with Tottenham Hotspur selling Gareth Bale to Real Madrid for 85 million in 2013, Manchester United's sale of Cristiano Ronaldo to Real Madrid for 80 million in 2009, and Liverpool selling Luis Suarez to Barcelona for 75 million in 2014. Question: In which year did Newcastle United pay 15 million to transfer Alan Shearer to their club?

Output: 1996

Input: Consider Input: Passage: As the Ottoman Empire gradually shrank in size, some 79 million Turkish-Muslims from its former territories in the Caucasus, Crimea, Balkans, and the Mediterranean islands migrated to Anatolia and Eastern Thrace. After the Empire lost the Balkan Wars (191213), it lost all its Balkan territories except East Thrace (European Turkey). This resulted in around 400,000 Muslims fleeing with the retreating Ottoman armies (with many dying from cholera brought by the soldiers), and with some 400,000 non-Muslims fleeing territory still under Ottoman rule. Justin McCarthy estimates that during the period 1821 to 1922 several million Muslims died in the Balkans, with the expulsion of a similar number. Question: Which individual estimated millions of Muslim deaths in the Balkans in the late 19th and early 20th century?
Output: Justin McCarthy
