Question: What is the age difference between the two children acting in the play? Passage 1:Groswin took over the position of nearby Altes Lager Menzlin as a trade center after its decline in the 9th century. The tribal affiliation of the inhabitants, though associated with the greater tribe of the Veleti, is uncertain - while the Ukrani are reported to have dwelled south of the Zarow and the Rani north of the Ryck river, the name of the medieval inhabitants of the area between these rivers is not reported. The lands of Groswin became a castellany of the Duchy of Pomerania during the westward expansion of Wartislaw I in the 1120s, and became part of the Bishopric of Cammin in 1140. In 1153, Stolpe Abbey was founded in the Groswin castellany as the first Pomeranian monastery. A market at the Groswin burgh is documented in 1159. In 1185, a Danish expedition led by Canut VI destroyed the burgh and devastated the castellany. Though the name Groswin stayed in use to refer to the area, the position of the former burgh as the areas center was taken over by nearby Anklam.

Andy Schleck, second overall, won the young riders' competition as he had the previous year. Franco Pellizotti originally won the polka dot jersey as the King of the Mountains, but had that result (along with all his 2009 results) stripped by the Court of Arbitration for Sport in 2011 due to his irregular values in the UCI's biological passport program detected in May 2010. and the King of the Mountains title was retroactively awarded to Egoi Martínez. Mark Cavendish won six stages, including the final stage on the Champs-Élysées, but was beaten in the points classification by Thor Hushovd, who consequently won the green jersey.

It is Fred, though, who has landed the leading role of Ebonezer Scrooge. Unfortunately, he has let his role go to his head, thinking himself a star and spending all of his time rehearsing his lines rather than focusing on his job or family. On Christmas Eve, in his rush to get to work, Fred forgets that he must take Pebbles to "cave care", and later to pick her up from cave care.
