Input: Read this: Later, von Neumann suggested a new method of linear programming, using the homogeneous linear system of Gordan (1873), which was later popularized by Karmarkar's algorithm. Von Neumann's method used a pivoting algorithm between simplices, with the pivoting decision determined by a nonnegative least squares subproblem with a convexity constraint (projecting the zero-vector onto the convex hull of the active simplex). Von Neumann's algorithm was the first interior point method of linear programming.
Question: What was the new method of linear programming that von Neumann suggested?

Output: homogeneous linear system of Gordan

Input: Read this: During the Nimrod Expedition led by Ernest Shackleton in 1907, parties led by Edgeworth David became the first to climb Mount Erebus and to reach the South Magnetic Pole. Douglas Mawson, who assumed the leadership of the Magnetic Pole party on their perilous return, went on to lead several expeditions until retiring in 1931. In addition, Shackleton himself and three other members of his expedition made several firsts in December 1908 February 1909: they were the first humans to traverse the Ross Ice Shelf, the first to traverse the Transantarctic Mountains (via the Beardmore Glacier), and the first to set foot on the South Polar Plateau. An expedition led by Norwegian polar explorer Roald Amundsen from the ship Fram became the first to reach the geographic South Pole on 14 December 1911, using a route from the Bay of Whales and up the Axel Heiberg Glacier. One month later, the doomed Scott Expedition reached the pole.
Question: Who led the party to first climb Mount Erebus?

Output: Edgeworth David

Input: Read this: The "yo yo" in the opinion polls continued into 1992, though after November 1990 any Labour lead in the polls was rarely sufficient for a majority. Major resisted Kinnock's calls for a general election throughout 1991. Kinnock campaigned on the theme "It's Time for a Change", urging voters to elect a new government after more than a decade of unbroken Conservative rule. However, the Conservatives themselves had undergone a dramatic change in the change of leader from Thatcher to Major, at least in terms of style if not substance. From the outset, it was clearly a well-received change, as Labour's 14-point lead in the November 1990 "Poll of Polls" was replaced by an 8% Tory lead a month later.
Question: When was any Conservative lead in the polls sufficient for a majority?

Output: unanswerable

Input: Read this: Ongoing political tensions between Great Britain and the thirteen colonies reached a crisis in 1774 when the British placed the province of Massachusetts under martial law after the Patriots protested taxes they regarded as a violation of their constitutional rights as Englishmen. When shooting began at Lexington and Concord in April 1775, militia units from across New England rushed to Boston and bottled up the British in the city. The Continental Congress appointed George Washington as commander-in-chief of the newly created Continental Army, which was augmented throughout the war by colonial militia. He drove the British out of Boston but in late summer 1776 they returned to New York and nearly captured Washington's army. Meanwhile, the revolutionaries expelled British officials from the 13 states, and declared themselves an independent nation on July 4, 1776.
Question: When did Britain declare martial law in a South American colony?

Output:
unanswerable
