Question: Which countries comprised the alliance that conquered and occupied Greece? Passage:Aside from the Romaniotes, a distinct Jewish population that historically lived in communities throughout Greece and neighboring areas with large Greek populations, Greece had a large population of Sephardi Jews, and is a historical center of Sephardic life; the city of Salonica or Thessaloniki, in Greek Macedonia, was called the "Mother of Israel". Greek Jews played an important role in the early development of Christianity, and became a source of education and commerce for the Byzantine Empire and throughout the period of Ottoman Greece, until suffering devastation in the Holocaust after Greece was conquered and occupied by the Axis powers despite efforts by Greeks to protect them. In the aftermath of the Holocaust, a large percentage of the surviving community emigrated to Israel or the United States.

Question: Which Philadelphia sport team with a fantasy creature mascot was found first? Passage:In the world of sports, mascots are also used for merchandising. Team mascots are often related to their respective team nicknames. This is especially true when the team's nickname is something that is a living animal and/or can be made to have humanlike characteristics. For more abstract nicknames, the team may opt to have an unrelated character serve as the mascot. For example, the athletic teams of the University of Alabama are nicknamed the Crimson Tide, while their mascot is an elephant named Big Al. Team mascots may take the form of a logo, person, live animal, inanimate object, or a costumed character, and often appear at team matches and other related events, sports mascots are often used as marketing tools for their teams to children. Since the mid-20th century, costumed characters have provided teams with an opportunity to choose a fantasy creature as their mascot, as is the case with the Philadelphia Phillies' mascot, the Phillie Phanatic, and the Philadelphia Flyers' mascot, Gritty.
