The problem: Answer a question about this article:
With the gold rush largely over by 1860, Melbourne continued to grow on the back of continuing gold mining, as the major port for exporting the agricultural products of Victoria, especially wool, and a developing manufacturing sector protected by high tariffs. An extensive radial railway network centred on Melbourne and spreading out across the suburbs and into the countryside was established from the late 1850s. Further major public buildings were begun in the 1860s and 1870s such as the Supreme Court, Government House, and the Queen Victoria Market. The central city filled up with shops and offices, workshops, and warehouses. Large banks and hotels faced the main streets, with fine townhouses in the east end of Collins Street, contrasting with tiny cottages down laneways within the blocks. The Aboriginal population continued to decline with an estimated 80% total decrease by 1863, due primarily to introduced diseases, particularly smallpox, frontier violence and dispossession from their lands.
How did Melbourne grow as major port for exporting the agricultural products?
****
The answer: gold mining


Problem: Please answer a question about the following article about Qing dynasty:
From 1889, when Guangxu began to rule in his own right, to 1898, the Empress Dowager lived in semi-retirement, spending the majority of the year at the Summer Palace. On November 1, 1897, two German Roman Catholic missionaries were murdered in the southern part of Shandong Province (the Juye Incident). In response, Germany used the murders as a pretext for a naval occupation of Jiaozhou Bay. The occupation prompted a "scramble for concessions" in 1898, which included the German lease of Jiazhou Bay, the Russian acquisition of Liaodong, and the British lease of the New Territories of Hong Kong.
When were two missionaries killed?
A: November 1, 1897,

Studies of this kind outside of Europe are even rarer, so it is difficult to make generalizations, but one small-scale study that compared transnational police information and intelligence sharing practices at specific cross-border locations in North America and Europe confirmed that low visibility of police information and intelligence sharing was a common feature (Alain, 2001). Intelligence-led policing is now common practice in most advanced countries (Ratcliffe, 2007) and it is likely that police intelligence sharing and information exchange has a common morphology around the world (Ratcliffe, 2007). James Sheptycki has analyzed the effects of the new information technologies on the organization of policing-intelligence and suggests that a number of 'organizational pathologies' have arisen that make the functioning of security-intelligence processes in transnational policing deeply problematic. He argues that transnational police information circuits help to "compose the panic scenes of the security-control society". The paradoxical effect is that, the harder policing agencies work to produce security, the greater are feelings of insecurity.

Where has cross-border policing been most under-studied?
Answer: outside of Europe


Problem: The New York Times reported that "government officials in Beijing and Sichuan have said they are investigating the collapses. In an acknowledgment of the weakness of building codes in the countryside, the National Development and Reform Commission said on May 27 that it had drafted an amendment to improve construction standards for primary and middle schools in rural areas. Experts are reviewing the draft, the commission said." To limit protests, officials pushed parents to sign a document, which forbade them from holding protests, in exchange of money, but some who refused to sign were threatened. The payment amounts varied from school to school but were approximately the same. In Hanwang, parents were offered a package valued at 8,800 USD in cash and a per-parent pension of nearly 5,600 USD. Furthermore, officials used other methods of silencing: riot police officers broke up protests by parents; the authorities set up cordons around the schools; and officials ordered the Chinese news media to stop reporting on school collapses.
What was given in exchange of signing the document?
The answer is the following: money

Here is a question about this article: In the tree a knot is either the base of a side branch or a dormant bud. A knot (when the base of a side branch) is conical in shape (hence the roughly circular cross-section) with the inner tip at the point in stem diameter at which the plant's vascular cambium was located when the branch formed as a bud.
What is the answer to this question: Because a knot's shape is conical, what shape does a cross-section of it have?
****
So...
circular
