Q: Question: Which of the two cities where McCartney was scheduled to headline has more residents? Passage:On 15 February 2016, McCartney announced two initial festival dates in Europe for the upcoming summer. These two headlining performances at Pinkpop Festival in Landgraaf, Netherlands and Rock Werchter in Werchter, Belgium were revealed before the initial revelation of the "One on One" tour. These tours would feature mostly similar elements of the "One on One" performances yet with a condensed set list to allot for festival curfew limits and less stage elements given restrictions. In the wake of the passing of notable Beatles and McCartney producer George Martin, McCartney announced the initial "One on One" dates for North America and Europe. In North America, McCartney's visit to Fresno, California would mark his first performance in the city, and his performances in North Little Rock and Sioux Falls would be his first performances in the states of Arkansas and South Dakota respectively. Elsewhere in North America, McCartney would perform in Portland after an eleven-year absence following his 2005 'US' tour. The two shows in Vancouver would follow his previous performance in the city at the BC Place stadium in 2012, yet this tour would feature two shows in the neighboring Rogers Arena after the pyrotechnics during his concert at BC Place accidentally damaged the stadium's new roof. McCartney's Seattle show would mark his shortest absence from any North American city on the tour announced currently, as he performed at the city's Safeco Field during the inaugural year of the 'Out There' tour. McCartney announced a performance on 16 March in Minneapolis at the Target Center. This show would take place on 4 May 2016, less than two years after McCartney's last performance in the city at the adjacent baseball stadium sharing a corporate sponsor with the arena, Target Field. Due to high demand of tickets a second show in Minneapolis was announced the next day and would take place on 5 May.

Q: 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.

Q: Question: How old was Rudi Gernreich when the monokini was introduced? Passage:By making an analogy with words like bilingual and bilateral containing the Latin prefix "bi-" (meaning "two" in Latin), the word bikini was first back-derived as consisting of two parts, [bi + kini] by Rudi Gernreich, who introduced the monokini in 1964. Later swimsuit designs like the tankini and trikini further cemented this derivation. Over time the "–kini family" (as dubbed by author William Safire), including the "–ini sisters" (as dubbed by designer Anne Cole), expanded into a variety of swimwear including the monokini (also known as a numokini or unikini), seekini, tankini, camikini, hikini (also hipkini), minikini, face-kini, burkini, and microkini. The Language Report, compiled by lexicographer Susie Dent and published by the Oxford University Press (OUP) in 2003, considers lexicographic inventions like bandeaukini and camkini, two variants of the tankini, important to observe. Although "bikini" was originally a registered trademark of Réard, it has since become genericized.
