Here is a question about this article: In the 11th century and the 12th century, the princes and their retinues, which were a mixture of Slavic and Scandinavian elites, dominated the society of Kievan Rus'. Leading soldiers and officials received income and land from the princes in return for their political and military services. Kievan society lacked the class institutions and autonomous towns that were typical of Western European feudalism. Nevertheless, urban merchants, artisans and labourers sometimes exercised political influence through a city assembly, the veche (council), which included all the adult males in the population. In some cases, the veche either made agreements with their rulers or expelled them and invited others to take their place. At the bottom of society was a stratum of slaves. More important was a class of tribute-paying peasants, who owed labour duty to the princes. The widespread personal serfdom characteristic of Western Europe did not exist in Kievan Rus'.
What is the answer to this question: Which two groups dominated the society of Kievan Rus?
****
So... mixture of Slavic and Scandinavian elites


Here is a question about this article: On 11 April 2006, Brian May and Roger Taylor appeared on the American singing contest television show American Idol. Each contestant was required to sing a Queen song during that week of the competition. Songs which appeared on the show included "Bohemian Rhapsody", "Fat Bottomed Girls", "The Show Must Go On", "Who Wants to Live Forever", and "Innuendo". Brian May later criticised the show for editing specific scenes, one of which made the group's time with contestant Ace Young look negative, despite it being the opposite. Taylor and May again appeared on the American Idol season 8 finale in May 2009, performing "We Are the Champions" with finalists Adam Lambert and Kris Allen. On 15 November 2009, Brian May and Roger Taylor appeared on the singing contest television show X Factor in the UK.

Here is a question about this article: Though it is the most played local derby in the history of La Liga, it is also the most unbalanced, with Barcelona overwhelmingly dominant. In the primera división league table, Espanyol has only managed to end above Barça on three occasions from 80 seasons (1928–2015) and the only all-Catalan Copa del Rey final was won by Barça in 1957. Espanyol has the consolation of achieving the largest margin win with a 6–0 in 1951, while Barcelona's biggest win was 5–0 on five occasions (in 1933, 1947, 1964, 1975 and 1992). Espanyol achieved a 2–1 win against Barça during the 2008–09 season, becoming the first team to defeat Barcelona at Camp Nou in their treble-winning season.
What is the answer to this question: Which team has the largest margin win?
****
So...
Espanyol
