Problem: Given the question: Given the following context:  At 475,442 square kilometres (183,569 sq mi), Cameroon is the world's 53rd-largest country. It is slightly larger than the nation of Sweden and the state of California; Cameroon is comparable in size to Papua New Guinea. The country is located in Central and West Africa, known as the hinge of Africa, on the Bight of Bonny, part of the Gulf of Guinea and the Atlantic Ocean. Cameroon lies between latitudes 1° and 13°N, and longitudes 8° and 17°E. Cameroon controls 12 nautical miles of the Atlantic Ocean. Tourist literature describes Cameroon as "Africa in miniature" because it exhibits all major climates and vegetation of the continent: coast, desert, mountains, rainforest, and savanna. The country's neighbours are Nigeria and the Atlantic Ocean to the west; Chad to the northeast; the Central African Republic to the east; and Equatorial Guinea, Gabon and the Republic of the Congo to the south. Cameroon is divided into five major geographic zones distinguished by dominant physical, climatic, and vegetative features. The coastal plain extends 15 to 150 kilometres (9 to 93 mi) inland from the Gulf of Guinea and has an average elevation of 90 metres (295 ft). Exceedingly hot and humid with a short dry season, this belt is densely forested and includes some of the wettest places on earth, part of the Cross-Sanaga-Bioko coastal forests.The South Cameroon Plateau rises from the coastal plain to an average elevation of 650 metres (2,133 ft). Equatorial rainforest dominates this region, although its alternation between wet and dry seasons makes it is less humid than the coast. This area is part of the Atlantic Equatorial coastal forests ecoregion.  answer the following question:  Which country has the Republic of the Congo to the south?

The answer is:
Cameroon


Problem: Given the question: Given the following context:  On July 9, 1790, Congress passed the Residence Act, which approved the creation of a national capital on the Potomac River. The exact location was to be selected by President George Washington, who signed the bill into law on July 16. Formed from land donated by the states of Maryland and Virginia, the initial shape of the federal district was a square measuring 10 miles (16 km) on each side, totaling 100 square miles (259 km2).Two pre-existing settlements were included in the territory: the port of Georgetown, Maryland, founded in 1751, and the city of Alexandria, Virginia, founded in 1749. During 1791–92, Andrew Ellicott and several assistants, including a free African American astronomer named Benjamin Banneker, surveyed the borders of the federal district and placed boundary stones at every mile point. Many of the stones are still standing.A new federal city was then constructed on the north bank of the Potomac, to the east of Georgetown. On September 9, 1791, the three commissioners overseeing the capital's construction named the city in honor of President Washington. The federal district was named Columbia (a feminine form of "Columbus"), which was a poetic name for the United States commonly in use at that time. Congress held its first session in Washington on November 17, 1800.Congress passed the District of Columbia Organic Act of 1801 that officially organized the District and placed the entire territory under the exclusive control of the federal government. Further, the unincorporated area within the District was organized into two counties: the County of Washington to the east of the Potomac and the County of Alexandria to the west. After the passage of this Act, citizens living in the District were no longer considered residents of Maryland or Virginia, which therefore ended their representation in Congress.  answer the following question:  What were the first names of the people who placed the stones that are still standing?
++++++++++++++++++++++++++++++++
The answer is:
Benjamin


Problem: Given the question: Given the following context:  Texas Rangers Gene Autry and Frog Millhouse are traveling undercover as western troubadours in search of the killer of old, half-blind Frank Martin. Their only clues are a guitar string (the murder weapon) and Martin's horse Swayback that hold the key to finding the dead man's lost goldmine. Following Frank Martin's funeral, Martin's granddaughter, Joan, meets her uncle, John Martin, and Lon Dillon, who flirts with her. Lawyer Henry Nolan reads Martin's will, revealing that the deceased left John $5,000 and the remainder of the estate to Joan.
