Input: Article: During the administration of U.S. President Martin Van Buren, nearly 17,000 Cherokees—along with approximately 2,000 black slaves owned by Cherokees—were uprooted from their homes between 1838 and 1839 and were forced by the U.S. military to march from "emigration depots" in Eastern Tennessee (such as Fort Cass) toward the more distant Indian Territory west of Arkansas. During this relocation an estimated 4,000 Cherokees died along the way west. In the Cherokee language, the event is called Nunna daul Isunyi—"the Trail Where We Cried." The Cherokees were not the only American Indians forced to emigrate as a result of the Indian removal efforts of the United States, and so the phrase "Trail of Tears" is sometimes used to refer to similar events endured by other American Indian peoples, especially among the "Five Civilized Tribes". The phrase originated as a description of the earlier emigration of the Choctaw nation.

Now answer this question: Which US President oversaw the forced westward relocation of Cherokees beginning in 1838?

Output: Martin Van Buren


Article: Imported Chinese labourers arrived in 1810, reaching a peak of 618 in 1818, after which numbers were reduced. Only a few older men remained after the British Crown took over the government of the island from the East India Company in 1834. The majority were sent back to China, although records in the Cape suggest that they never got any farther than Cape Town. There were also a very few Indian lascars who worked under the harbour master.

Question: How many imported Chinese laborers were there at the peak of importation?
Ans: 618

Problem: Please answer a question about the following article about London:
The pilgrims in Geoffrey Chaucer's late 14th-century Canterbury Tales set out for Canterbury from London – specifically, from the Tabard inn, Southwark. William Shakespeare spent a large part of his life living and working in London; his contemporary Ben Jonson was also based there, and some of his work—most notably his play The Alchemist—was set in the city. A Journal of the Plague Year (1722) by Daniel Defoe is a fictionalisation of the events of the 1665 Great Plague. Later important depictions of London from the 19th and early 20th centuries are Dickens' novels, and Arthur Conan Doyle's Sherlock Holmes stories. Modern writers pervasively influenced by the city include Peter Ackroyd, author of a "biography" of London, and Iain Sinclair, who writes in the genre of psychogeography.
Arthur Conan Doyle brought to life what famous detective in a series of novels?
A: Sherlock Holmes


Question: Read this and answer the question

Several companies, refusing to pay the licensing fee or having been rejected by Nintendo, found ways to circumvent the console's authentication system. Most of these companies created circuits that used a voltage spike to temporarily disable the 10NES chip in the NES. A few unlicensed games released in Europe and Australia came in the form of a dongle that would be connected to a licensed game, in order to use the licensed game's 10NES chip for authentication. In order to combat unlicensed games, Nintendo of America threatened retailers who sold them with losing their supply of licensed titles. In addition, multiple revisions were made to the NES PCBs to prevent these games from working.

Why did the companies circumvent the authentication system?
Answer:
refusing to pay the licensing fee or having been rejected by Nintendo
