Problem: Please answer a question about the following article about FA Cup:
The FA permitted artificial turf (3G) pitches in all rounds of the competition from the 2014–15 edition and beyond. Under the 2015-16 rules, the pitch must be of FIFA One Star quality, or Two Star for ties if they involve one of the 92 professional clubs. This followed approval two years previously for their use in the qualifying rounds only - if a team with a 3G pitch progressed to the competition proper, they had to switch their tie to the ground of another eligible entrant with a natural grass pitch. Having been strong proponents of the surface, the first match in the proper rounds to be played on a 3G surface was a televised first round replay at Maidstone United's Gallagher Stadium on 20 November 2015.
How many professional clubs are there? 
A: 92
Problem: Please answer a question about the following article about Political philosophy:
Communism remained an important focus especially during the 1950s and 1960s. Colonialism and racism were important issues that arose. In general, there was a marked trend towards a pragmatic approach to political issues, rather than a philosophical one. Much academic debate regarded one or both of two pragmatic topics: how (or whether) to apply utilitarianism to problems of political policy, or how (or whether) to apply economic models (such as rational choice theory) to political issues. The rise of feminism, LGBT social movements and the end of colonial rule and of the political exclusion of such minorities as African Americans and sexual minorities in the developed world has led to feminist, postcolonial, and multicultural thought becoming significant. This led to a challenge to the social contract by philosophers Charles W. Mills in his book The Racial Contract and Carole Patemen in her book The Sexual Contract that the social contract excluded persons of colour and women respectively.
Who wrote The Racial Contract?
A: Charles W. Mills
Problem: Please answer a question about the following article about Carnival:
Carnaval de Solsona takes place in Solsona, Lleida. It is one of the longest; free events in the streets, and nightly concerts run for more than a week. The Carnival is known for a legend that explains how a donkey was hung at the tower bell − because the animal wanted to eat grass that grew on the top of the tower. To celebrate this legend, locals hang a stuffed donkey at the tower that "pisses" above the excited crowd using a water pump. This event is the most important and takes place on Saturday night. For this reason, the inhabitants are called "matarrucs" ("donkey killers").
How long can the nightly concerts run for?
A:
more than a week
