Problem: Queen (band):

In February 1981, Queen travelled to South America as part of The Game Tour, and became the first major rock band to play in Latin American stadiums. The tour included five shows in Argentina, one of which drew the largest single concert crowd in Argentine history with an audience of 300,000 in Buenos Aires and two concerts at the Morumbi Stadium in São Paulo, Brazil, where they played to an audience of more than 131,000 people in the first night (then the largest paying audience for a single band anywhere in the world) and more than 120,000 people the following night. In October of the same year, Queen performed for more than 150,000 fans on 9 October at Monterrey (Estadio Universitario) and 17 and 18 at Puebla (Estadio Zaragoza), Mexico. On 24 and 25 November, Queen played two sell out nights at the Montreal Forum, Quebec, Canada. One of Mercury's most notable performances of The Game's final track, "Save Me", took place in Montreal, and the concert is recorded in the live album, Queen Rock Montreal.

Problem: Chihuahua (state):

Maximilian was deeply dissatisfied with General Bazaine's decision to abandon the state capital of Chihuahua and immediately ordered Agustín B. Billaut to recapture the city. On December 11, 1865, Billaut with a force of 500 men took control of the city. By January 31, 1866 Billaut was ordered to leave Chihuahua, but he left behind 500 men to maintain control. At the zenith of their power, the imperialist forces controlled all but four states in Mexico; the only states to maintain strong opposition to the French were: Guerrero, Chihuahua, Sonora, and Baja California.

How many men did Billaut have when he recaptured the city?
---
A: 500


Problem: Sumer:

The almost constant wars among the Sumerian city-states for 2000 years helped to develop the military technology and techniques of Sumer to a high level. The first war recorded in any detail was between Lagash and Umma in c. 2525 BC on a stele called the Stele of the Vultures. It shows the king of Lagash leading a Sumerian army consisting mostly of infantry. The infantrymen carried spears, wore copper helmets, and carried rectangular shields. The spearmen are shown arranged in what resembles the phalanx formation, which requires training and discipline; this implies that the Sumerians may have made use of professional soldiers.

How many years were the Sumerian city-states at war?
---
A: 2000 years


Problem: Karl Popper:

While there is some dispute as to the matter of influence, Popper had a long-standing and close friendship with economist Friedrich Hayek, who was also brought to the London School of Economics from Vienna. Each found support and similarities in the other's work, citing each other often, though not without qualification. In a letter to Hayek in 1944, Popper stated, "I think I have learnt more from you than from any other living thinker, except perhaps Alfred Tarski." Popper dedicated his Conjectures and Refutations to Hayek. For his part, Hayek dedicated a collection of papers, Studies in Philosophy, Politics, and Economics, to Popper, and in 1982 said, "...ever since his Logik der Forschung first came out in 1934, I have been a complete adherent to his general theory of methodology."

Who did Popper say was the only thinker who might have had a greater influence on him than Hayek?
---
A:
Alfred Tarski
