Question: Which of the cities where the cup matches have been held has a larger population? Passage:In 2002, the International Ice Hockey Federation (IIHF) announced that it would acknowledge the site of Victoria Rink with "a commemorative plaque or other historical site marker to remind the passers-by of the existence of the Victoria Skating Rink, the birthplace of organized hockey." The commemoration has been marked in two ways. On May 22, 2008, a commemorative plaque was dedicated at the nearby Centre Bell, along with a plaque honouring James Creighton. Further, the IIHF created the Victoria Cup, a trophy named for the arena, for which—along with 1 million Swiss francs—one National Hockey League team and the champion of the European Champions Hockey League play-off annually. The first Cup match was held in Berne, Switzerland on October 1, 2008 between the New York Rangers and the Metallurg Magnitogorsk. The next, and last, edition of the Victoria Cup was held in Zurich on September 29, 2009, between the ZSC Lions and the Chicago Blackhawks.

Question: Why did de Angeli choose the names she did for her characters in her first book? Passage:In 1908, she met John Dailey de Angeli, a violinist, known as Dai. They were married in Toronto on April 12,1910. The first of their six children, John Shadrach de Angeli, was born one year later. After living in many locations in the American and Canadian West, they settled in the Philadelphia suburb of Collingswood, New Jersey. There in 1921 Marguerite started to study drawing under her mentor, Maurice Bower. In 1922, Marguerite began illustrating a Sunday School paper and was soon doing illustrations for magazines such as The Country Gentleman, Ladies' Home Journal, and The American Girl, besides illustrating books for authors including Helen Ferris, Elsie Singmaster, Cornelia Meigs, and Dorothy Canfield Fisher. Her last child, Maurice Bower de Angeli, was born in 1928, seven years before the 1935 publication of her first book, Ted and Nina Go to the Grocery Store. The de Angeli family moved frequently, returning to Pennsylvania and living north of Philadelphia in Jenkintown, west of Philadelphia in the Manoa neighborhood of Havertown, on Carpenter Lane in Germantown, Philadelphia, on Panama Street in Center City, Philadelphia, in an apartment near the Philadelphia Art Museum, and in a cottage in Green Lane, Pennsylvania. They also maintained a summer cabin on Money Island in Toms River, New Jersey. Marguerite's husband died in 1969, eight months before their 60th wedding anniversary.
