Question: Was the Belgian Labour Party socialist? Passage:Achille Honoré Van Acker was born into a working class family in Bruges, Belgium in 1898 as the youngest of 12 children. He only attended school until the age of 11. Despite entering the workforce, Van Acker read widely and joined several social associations in Bruges. At the outbreak of World War I, he was refused by the Belgian Army because he suffered from astigmatism. While the Germans occupied most of Belgium, Van Acker fled into the small section of unoccupied territory behind the Yser Front where he worked in various menial capacities. Mixing with Belgian soldiers during the war, Van Acker became involved in socialist politics, developing a distinctive ideology based on moderate social democracy. After the end of the war, he returned to Bruges and joined the Belgian Labour Party (Belgische Werkliedenpartij, POB–BWP) and became active in socialist groups, trade unions, and cooperatives.

Question: How old was Art Hodes the year Dane appeared with Jackie Gleason? Passage:By 1959, Louis Armstrong had asked Time magazine readers: "Did you get that chick? She's a gasser!" and invited her to appear with him on national television. She appeared with Armstrong on the Timex All-Star Jazz Show hosted by Jackie Gleason on January 7, 1959. She toured the East Coast with Jack Teagarden, appeared in Chicago with Art Hodes, Roosevelt Sykes, Little Brother Montgomery, Memphis Slim, Otis Spann, Willie Dixon and others, played New York with Wilbur De Paris and his band, and appeared on The Tonight Show Starring Johnny Carson as a solo guest artist. Other national TV work included The Steve Allen Show, Bobby Troup's Stars of Jazz, and Alfred Hitchcock Presents. In 1961, the singer opened her own club, Sugar Hill: Home of the Blues, on San Francisco's Broadway in the North Beach district, with the idea of creating a venue for the blues in a tourist district where a wider audience could hear it. There Dane performed regularly with her two most constant musical companions: Kenny "Good News" Whitson on piano and cornet and Wellman Braud, former Ellington bassist.
