Arsenal fans often refer to themselves as "Gooners", the name derived from the team's nickname, "The Gunners". The fanbase is large and generally loyal, and virtually all home matches sell out; in 2007–08 Arsenal had the second-highest average League attendance for an English club (60,070, which was 99.5% of available capacity), and, as of 2015, the third-highest all-time average attendance. Arsenal have the seventh highest average attendance of European football clubs only behind Borussia Dortmund, FC Barcelona, Manchester United, Real Madrid, Bayern Munich, and Schalke. The club's location, adjoining wealthy areas such as Canonbury and Barnsbury, mixed areas such as Islington, Holloway, Highbury, and the adjacent London Borough of Camden, and largely working-class areas such as Finsbury Park and Stoke Newington, has meant that Arsenal's supporters have come from a variety of social classes.

Where did the attendance at Arsenal games rank in relation to other English clubs?
Answer: second-highest average


Problem: Some agriculturalists also regularly hunt and gather (e.g., farming during the frost-free season and hunting during the winter). Still others in developed countries go hunting, primarily for leisure. In the Brazilian rainforest, those groups that recently did, or even continue to, rely on hunting and gathering techniques seem to have adopted this lifestyle, abandoning most agriculture, as a way to escape colonial control and as a result of the introduction of European diseases reducing their populations to levels where agriculture became difficult.[citation needed][dubious – discuss]
Why would they leave agricultural lifestyle?
The answer is the following: to escape colonial control

Here is a question about this article: Valencia is a bilingual city: Valencian and Spanish are the two official languages. Spanish is official in all of Spain, whereas Valencian is official in the Valencian Country, as well as in Catalonia and the Balearic Islands, where it receives the name of Catalan. Despite the differentiated denomination, the distinct dialectal traits and political tension between Catalonia and the Valencian Country, Catalan and Valencian are mutually intelligible and are considered two varieties of the same language.
Valencian has been historically repressed in favour of Spanish. The effects have been more noticeable in the city proper, whereas the language has remained active in the rural and metropolitan areas. After the Castille-Aragon unification, a Spanish-speaking elite established itself in the city. In more recent history, the establishment of Franco's military and administrative apparatus in Valencia further excluded Valencian from public life. Valencian recovered its official status, prestige and use in education after the transition to democracy in 1978. However, due to industrialisation in recent decades, Valencia has attracted immigration from other regions in Spain, and hence there is also a demographic factor for its declining social use. Due to a combination of these reasons, Valencia has become the bastion of anti-Catalan blaverism, which celebrates Valencian as merely folkloric, but rejects the existing standard which was adapted from Catalan orthography.
Spanish is currently the predominant language in the city proper but, thanks to the education system, most Valencians have basic knowledge of both Spanish and Valencian, and either can be used in the city. Valencia is therefore the second biggest Catalan-speaking city after Barcelona. Institutional buildings and streets are named in Valencian. The city is also home to many pro-Valencian political and civil organisations. Furthermore, education entirely in Valencian is offered in more than 70 state-owned schools in the city, as well as by the University of Valencia across all disciplines.
What is the answer to this question: How many official languages does Valencia have?
****
So...
two
