Here is a question about this article: The digital data on a CD begins at the center of the disc and proceeds toward the edge, which allows adaptation to the different size formats available. Standard CDs are available in two sizes. By far, the most common is 120 millimetres (4.7 in) in diameter, with a 74- or 80-minute audio capacity and a 650 or 700 MiB (737,280,000-byte) data capacity. This capacity was reportedly specified by Sony executive Norio Ohga in May 1980 so as to be able to contain the entirety of the London Philharmonic Orchestra's recording of Beethoven's Ninth Symphony on one disc. This is a myth according to Kees Immink, as the code format had not yet been decided in May 1980. The adoption of EFM one month later would have allowed a playing time of 97 minutes for 120 mm diameter or 74 minutes for a disc as small as 100 mm. The 120 mm diameter has been adopted by subsequent formats, including Super Audio CD, DVD, HD DVD, and Blu-ray Disc. Eighty-millimeter discs ("Mini CDs") were originally designed for CD singles and can hold up to 24 minutes of music or 210 MiB of data but never became popular.[citation needed] Today, nearly every single is released on a 120 mm CD, called a Maxi single.[citation needed]
What is the answer to this question: What is the size of a Maxi Single?
****
So... 120 mm


The problem: Answer a question about this article:
Avicenna's consideration of the essence-attributes question may be elucidated in terms of his ontological analysis of the modalities of being; namely impossibility, contingency, and necessity. Avicenna argued that the impossible being is that which cannot exist, while the contingent in itself (mumkin bi-dhatihi) has the potentiality to be or not to be without entailing a contradiction. When actualized, the contingent becomes a 'necessary existent due to what is other than itself' (wajib al-wujud bi-ghayrihi). Thus, contingency-in-itself is potential beingness that could eventually be actualized by an external cause other than itself. The metaphysical structures of necessity and contingency are different. Necessary being due to itself (wajib al-wujud bi-dhatihi) is true in itself, while the contingent being is 'false in itself' and 'true due to something else other than itself'. The necessary is the source of its own being without borrowed existence. It is what always exists.
According to Avicenna, what always exists?
****
The answer: The necessary


Problem: Please answer a question about the following article about FA Cup:
After being rendered obsolete by the redesign, the 1895 replica was presented in 1910 to the FA's long-serving president Lord Kinnaird. Kinnaird died in 1923, and his family kept it in their possession, out of view, until putting it up for auction in 2005. It was duly sold at Christie's auction house on 19 May 2005 for £420,000 (£478,400 including auction fees and taxes). The sale price set a new world record for a piece of football memorabilia, surpassing the £254,000 paid for the Jules Rimet World Cup Trophy in 1997. The successful bidder was David Gold, the then joint chairman of Birmingham City; claiming the FA and government were doing nothing proactive to ensure the trophy remained in the country, Gold stated his purchase was motivated by wanting to save it for the nation. Accordingly, Gold presented the trophy to the National Football Museum in Preston on 20 April 2006, where it went on immediate public display. It later moved with the museum to its new location in Manchester. In November 2012, it was ceremonially presented to Royal Engineers, after they beat Wanderers 7–1 in a charity replay of the first FA Cup final.
Where did it sell? 
A: Christie's auction house on 19 May 2005 for £420,000 (£478,400 including auction fees and taxes)


Question: Read this and answer the question

Infrared vibrational spectroscopy (see also near-infrared spectroscopy) is a technique that can be used to identify molecules by analysis of their constituent bonds. Each chemical bond in a molecule vibrates at a frequency characteristic of that bond. A group of atoms in a molecule (e.g., CH2) may have multiple modes of oscillation caused by the stretching and bending motions of the group as a whole. If an oscillation leads to a change in dipole in the molecule then it will absorb a photon that has the same frequency. The vibrational frequencies of most molecules correspond to the frequencies of infrared light. Typically, the technique is used to study organic compounds using light radiation from 4000–400 cm−1, the mid-infrared. A spectrum of all the frequencies of absorption in a sample is recorded. This can be used to gain information about the sample composition in terms of chemical groups present and also its purity (for example, a wet sample will show a broad O-H absorption around 3200 cm−1).

What is the technique that analyzes the constituent bonds of molecules to identify them?
Answer: Infrared vibrational spectroscopy


Problem: In Anglo-American academic political philosophy, the publication of John Rawls's A Theory of Justice in 1971 is considered a milestone. Rawls used a thought experiment, the original position, in which representative parties choose principles of justice for the basic structure of society from behind a veil of ignorance. Rawls also offered a criticism of utilitarian approaches to questions of political justice. Robert Nozick's 1974 book Anarchy, State, and Utopia, which won a National Book Award, responded to Rawls from a libertarian perspective and gained academic respectability for libertarian viewpoints.
Who wrote Anarchy, State, and Utopia?
The answer is the following: Robert Nozick


Input: Article: As of the 2015–16 season, Premier League football has been played in 53 stadiums since the formation of the Premier League in 1992. The Hillsborough disaster in 1989 and the subsequent Taylor Report saw a recommendation that standing terraces should be abolished; as a result all stadiums in the Premier League are all-seater. Since the formation of the Premier League, football grounds in England have seen constant improvements to capacity and facilities, with some clubs moving to new-build stadiums. Nine stadiums that have seen Premier League football have now been demolished. The stadiums for the 2010–11 season show a large disparity in capacity: Old Trafford, the home of Manchester United has a capacity of 75,957 with Bloomfield Road, the home of Blackpool, having a capacity of 16,220. The combined total capacity of the Premier League in the 2010–11 season is 770,477 with an average capacity of 38,523.

Now answer this question: In how many stadiums had Premier League been played as of the 2015-16 season?

Output:
53
