Problem: John von Neumann:

With this contribution of von Neumann, the axiomatic system of the theory of sets became fully satisfactory, and the next question was whether or not it was also definitive, and not subject to improvement. A strongly negative answer arrived in September 1930 at the historic mathematical Congress of Konigsberg, in which Kurt Godel announced his first theorem of incompleteness: the usual axiomatic systems are incomplete, in the sense that they cannot prove every truth which is expressible in their language. This result was sufficiently innovative as to confound the majority of mathematicians of the time.

What was the central theme of Godel's announcement that the axiomatic system was not complete?
---
A: they cannot prove every truth which is expressible in their language

Problem: The Han dynasty inherited the ban liang coin type from the Qin. In the beginning of the Han, Emperor Gaozu closed the government mint in favor of private minting of coins. This decision was reversed in 186 BC by his widow Grand Empress Dowager Lu Zhi (d. 180 BC), who abolished private minting. In 182 BC, Lu Zhi issued a bronze coin that was much lighter in weight than previous coins. This caused widespread inflation that was not reduced until 175 BC when Emperor Wen allowed private minters to manufacture coins that were precisely 2.6 g (0.09 oz) in weight.
In what year was the decision reversing the closure of the government mint implemented?
---
Answer: 186 BC

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Violent incidents occurred throughout the Piedmont of the state as white insurgents struggled to maintain white supremacy in the face of social changes after the war and granting of citizenship to freedmen by federal constitutional amendments. After former Confederates were allowed to vote again, election campaigns from 1872 on were marked by violent intimidation of blacks and Republicans by white Democratic paramilitary groups, known as the Red Shirts. Violent incidents took place in Charleston on King Street in September 6 and in nearby Cainhoy on October 15, both in association with political meetings before the 1876 election. The Cainhoy incident was the only one statewide in which more whites were killed than blacks. The Red Shirts were instrumental in suppressing the black Republican vote in some areas in 1876 and narrowly electing Wade Hampton as governor, and taking back control of the state legislature. Another riot occurred in Charleston the day after the election, when a prominent Republican leader was mistakenly reported killed.
What were white Democratic paramilitary groups in Charleston known as?
A: the Red Shirts

Context and question: Purebred dogs of one breed are genetically distinguishable from purebred dogs of other breeds, but the means by which kennel clubs classify dogs is unsystematic. Systematic analyses of the dog genome has revealed only four major types of dogs that can be said to be statistically distinct. These include the "old world dogs" (e.g., Malamute and Shar Pei), "Mastiff"-type (e.g., English Mastiff), "herding"-type (e.g., Border Collie), and "all others" (also called "modern"- or "hunting"-type).
What are the other modern and hunting types of dogs called?
Answer: all others

Question: Another residence was maintained at Lake Bled, while the grounds at Karaorevo were the site of "diplomatic hunts". By 1974 the Yugoslav President had at his disposal 32 official residences, larger and small, the yacht Galeb ("seagull"), a Boeing 727 as the presidential airplane, and the Blue Train. After Tito's death the presidential Boeing 727 was sold to Aviogenex, the Galeb remained docked in Montenegro, while the Blue Train was stored in a Serbian train shed for over two decades. While Tito was the person who held the office of president for by far the longest period, the associated property was not private and much of it continues to be in use by Yugoslav successor states, as public property, or maintained at the disposal of high-ranking officials.
Is there an answer to this question: What is the English translation of Galeb?

Answer: seagull

Problem: Montana:

In 1940, Jeannette Rankin had once again been elected to Congress, and in 1941, as she did in 1917, she voted against the United States' declaration of war. This time she was the only vote against the war, and in the wake of public outcry over her vote, she required police protection for a time. Other pacifists tended to be those from "peace churches" who generally opposed war. Many individuals from throughout the U.S. who claimed conscientious objector status were sent to Montana during the war as smokejumpers and for other forest fire-fighting duties.

What were conscientious objectors sent to Montana to do?
---
A:
smokejumpers and for other forest fire-fighting duties.
