Problem: John von Neumann:

Von Neumann was the first to establish a rigorous mathematical framework for quantum mechanics, known as the Diracvon Neumann axioms, with his 1932 work Mathematical Foundations of Quantum Mechanics. After having completed the axiomatization of set theory, he began to confront the axiomatization of quantum mechanics. He realized, in 1926, that a state of a quantum system could be represented by a point in a (complex) Hilbert space that, in general, could be infinite-dimensional even for a single particle. In this formalism of quantum mechanics, observable quantities such as position or momentum are represented as linear operators acting on the Hilbert space associated with the quantum system.

What von Neumann work preceded the axiomatiztion of quatum mechanics?
---
A: axiomatization of set theory

Problem: 2008 Summer Olympics torch relay:

Several hundred pro-Tibet protesters gathered at the Trocadero with banners and Tibetan flags, and remained there for a peaceful protest, never approaching the torch relay itself. Among them was Jane Birkin, who spoke to the media about the "lack of freedom of speech" in China. Also present was Thupten Gyatso, President of the French Tibetan community, who called upon pro-Tibet demonstrators to "remain calm, non-violent, peaceful".

Where did pro-Tibetan protesters get together?
---
A: Trocadero

Problem: Premier League:

The years following 2009 marked a shift in the structure of the "Big Four" with Tottenham Hotspur and Manchester City both breaking into the top four. In the 200910 season, Tottenham finished fourth and became the first team to break the top four since Everton in 2005. Criticism of the gap between an elite group of "super clubs" and the majority of the Premier League has continued, nevertheless, due to their increasing ability to spend more than the other Premier League clubs. Manchester City won the title in the 201112 season, becoming the first club outside the "Big Four" to win since 199495. That season also saw two of the Big Four (Chelsea and Liverpool) finish outside the top four places for the first time since 199495.

Which team finished fourth in the 2009-10 season?
---
A: In the 200910 season, Tottenham finished fourth and became the first team to break the top four since Everton in 2005

Problem: Muslim world:

In astronomy, Muhammad ibn Jabir al-Harrani al-Battani improved the precision of the measurement of the precession of the Earth's axis. The corrections made to the geocentric model by al-Battani, Averroes, Nasir al-Din al-Tusi, Mu'ayyad al-Din al-'Urdi and Ibn al-Shatir were later incorporated into the Copernican heliocentric model. Heliocentric theories were also discussed by several other Muslim astronomers such as Al-Biruni, Al-Sijzi, Qotb al-Din Shirazi, and Najm al-Din al-Qazwini al-Katibi. The astrolabe, though originally developed by the Greeks, was perfected by Islamic astronomers and engineers, and was subsequently brought to Europe.

What work is Muhammad ibn Jabir al-Harrani al-Battani known for as it regards to earth?
---
A:
improved the precision of the measurement of the precession of the Earth's axis
