In Charleston, the African American population increased as freedmen moved from rural areas to the major city: from 17,000 in 1860 to over 27,000 in 1880. Historian Eric Foner noted that blacks were glad to be relieved of the many regulations of slavery and to operate outside of white surveillance. Among other changes, most blacks quickly left the Southern Baptist Church, setting up their own black Baptist congregations or joining new African Methodist Episcopal Church and AME Zion churches, both independent black denominations first established in the North. Freedmen "acquired dogs, guns, and liquor (all barred to them under slavery), and refused to yield the sidewalks to whites".

How many African Americans lived in Charleston in 1860?
Answer: 17,000

Problem: Outstanding debts were also agreed and the company permitted to export 250 tons of saltpetre. Again in 1673, Banks successfully negotiated another contract for 700 tons of saltpetre at 37,000 between the king and the company. So urgent was the need to supply the armed forces in the United Kingdom, America and elsewhere that the authorities sometimes turned a blind eye on the untaxed sales. One governor of the company was even reported as saying in 1864 that he would rather have the saltpetre made than the tax on salt.
how much did 700 tons of saltpetre go for in the contract negotiated by Banks in 1673
The answer is the following: 37,000

Input: Computer
In time, the network spread beyond academic and military institutions and became known as the Internet. The emergence of networking involved a redefinition of the nature and boundaries of the computer. Computer operating systems and applications were modified to include the ability to define and access the resources of other computers on the network, such as peripheral devices, stored information, and the like, as extensions of the resources of an individual computer. Initially these facilities were available primarily to people working in high-tech environments, but in the 1990s the spread of applications like e-mail and the World Wide Web, combined with the development of cheap, fast networking technologies like Ethernet and ADSL saw computer networking become almost ubiquitous. In fact, the number of computers that are networked is growing phenomenally. A very large proportion of personal computers regularly connect to the Internet to communicate and receive information. "Wireless" networking, often utilizing mobile phone networks, has meant networking is becoming increasingly ubiquitous even in mobile computing environments.

The network spread to be known as what today?
Output: the Internet.

Input: Article: Real estate is a major force in the city's economy, as the total value of all New York City property was assessed at US$914.8 billion for the 2015 fiscal year.

According to Forbes, in 2014, Manhattan was home to six of the top ten zip codes in the United States by median housing price.

Problem: In consequence to the Reform War, the federal government was bankrupt and could not pay its foreign debts to Spain, England, and France. On July 17, 1861, President Juarez decreed a moratorium on payment to foreign debtors for a period of two years. Spain, England, and France did not accept the moratorium by Mexico; they united at the Convention of the Triple Alliance on October 31, 1861 in which they agreed to take possession of several custom stations within Mexico as payment. A delegation of the Triple Alliance arrived in Veracruz in December 1861. President Juarez immediately sent his Foreign Affairs Minister, Manuel Doblado, who is able to reduce the debts through the Pacto de Soledad (Soledad Pact). General Juan Prim of Spain persuaded the English delegation to accept the terms of the Pacto de Soledad, but the French delegation refused.
Who convinced the English to accept the terms of the pact?
The answer is the following:
General Juan Prim of Spain
