Problem: Great Plains:

The railroads opened up the Great Plains for settlement, for now it was possible to ship wheat and other crops at low cost to the urban markets in the East, and Europe. Homestead land was free for American settlers. Railroads sold their land at cheap rates to immigrants in expectation they would generate traffic as soon as farms were established. Immigrants poured in, especially from Germany and Scandinavia. On the plains, very few single men attempted to operate a farm or ranch by themselves; they clearly understood the need for a hard-working wife, and numerous children, to handle the many chores, including child-rearing, feeding and clothing the family, managing the housework, feeding the hired hands, and, especially after the 1930s, handling paperwork and financial details. During the early years of settlement, farm women played an integral role in assuring family survival by working outdoors. After approximately one generation, women increasingly left the fields, thus redefining their roles within the family. New technology including sewing and washing machines encouraged women to turn to domestic roles. The scientific housekeeping movement, promoted across the land by the media and government extension agents, as well as county fairs which featured achievements in home cookery and canning, advice columns for women regarding farm bookkeeping, and home economics courses in the schools.

what did the railroads make it easy to do?
---
A: ship wheat and other crops


Problem: According to both indigenous American and European accounts and documents, American civilizations at the time of European encounter had achieved many accomplishments. For instance, the Aztecs built one of the largest cities in the world, Tenochtitlan, the ancient site of Mexico City, with an estimated population of 200,000. American civilizations also displayed impressive accomplishments in astronomy and mathematics. The domestication of maize or corn required thousands of years of selective breeding.
What had the civilizations in the Americas achieved by the time the Europeans encountered them?
---
Answer: many accomplishments


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The axiomatization of mathematics, on the model of Euclid's Elements, had reached new levels of rigour and breadth at the end of the 19th century, particularly in arithmetic, thanks to the axiom schema of Richard Dedekind and Charles Sanders Peirce, and geometry, thanks to David Hilbert. At the beginning of the 20th century, efforts to base mathematics on naive set theory suffered a setback due to Russell's paradox (on the set of all sets that do not belong to themselves). The problem of an adequate axiomatization of set theory was resolved implicitly about twenty years later by Ernst Zermelo and Abraham Fraenkel. Zermelo–Fraenkel set theory provided a series of principles that allowed for the construction of the sets used in the everyday practice of mathematics. But they did not explicitly exclude the possibility of the existence of a set that belongs to itself. In his doctoral thesis of 1925, von Neumann demonstrated two techniques to exclude such sets—the axiom of foundation and the notion of class.
What 2 techniques did Von Neumann use to exclude sets in his doctoral thesis in 1925?
A: the axiom of foundation and the notion of class.


Context and question: When the board has no embedded components it is more correctly called a printed wiring board (PWB) or etched wiring board. However, the term printed wiring board has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). The IPC preferred term for assembled boards is circuit card assembly (CCA), and for assembled backplanes it is backplane assemblies. The term PCB is used informally both for bare and assembled boards.
What's the abbreviation for a printed wiring board?
Answer: PWB


Question: After the Indian Rebellion of 1857, the British East India Company, which had ruled much of India, was dissolved, and Britain's possessions and protectorates on the Indian subcontinent were formally incorporated into the British Empire. The Queen had a relatively balanced view of the conflict, and condemned atrocities on both sides. She wrote of "her feelings of horror and regret at the result of this bloody civil war", and insisted, urged on by Albert, that an official proclamation announcing the transfer of power from the company to the state "should breathe feelings of generosity, benevolence and religious toleration". At her behest, a reference threatening the "undermining of native religions and customs" was replaced by a passage guaranteeing religious freedom.
Is there an answer to this question: Who encouraged Victoria to issue an official statement on the conflict of the civil war in India? 

Answer: Albert


QUES: On 21 December 2011 the bank instituted a programme of making low-interest loans with a term of three years (36 months) and 1% interest to European banks accepting loans from the portfolio of the banks as collateral. Loans totalling €489.2 bn (US$640 bn) were announced. The loans were not offered to European states, but government securities issued by European states would be acceptable collateral as would mortgage-backed securities and other commercial paper that can be demonstrated to be secure. The programme was announced on 8 December 2011 but observers were surprised by the volume of the loans made when it was implemented. Under its LTRO it loaned €489bn to 523 banks for an exceptionally long period of three years at a rate of just one percent. The by far biggest amount of €325bn was tapped by banks in Greece, Ireland, Italy and Spain. This way the ECB tried to make sure that banks have enough cash to pay off €200bn of their own maturing debts in the first three months of 2012, and at the same time keep operating and loaning to businesses so that a credit crunch does not choke off economic growth. It also hoped that banks would use some of the money to buy government bonds, effectively easing the debt crisis.

What would happen if some of the banks were to forbid buying government bonds?
