input: Please answer the following: Extract the answer to the question from the following context. Question: Which of the following is not a landscape architect: Roberto Burle Marx or Buriti Palace? Context: A series of low-lying annexes (largely hidden) flank both ends. Also in the square are the glass-faced Planalto Palace housing the presidential offices, and the Palace of the Supreme Court. Farther east, on a triangle of land jutting into the lake, is the Palace of the Dawn (Palacio da Alvorada; the presidential residence). Between the federal and civic buildings on the Monumental Axis is the city's cathedral, considered by many to be Niemeyer's finest achievement (see photographs of the interior). The parabolically shaped structure is characterized by its 16 gracefully curving supports, which join in a circle 115 feet (35 meters) above the floor of the nave; stretched between the supports are translucent walls of tinted glass. The nave is entered via a subterranean passage rather than conventional doorways. Other notable buildings are Buriti Palace, Itamaraty Palace, the National Theater, and several foreign embassies that creatively embody features of their national architecture. The Brazilian landscape architect Roberto Burle Marx designed landmark modernist gardens for some of the principal buildings.

Please answer this: Extract the answer to the question from the following context. Question: Above where was Powers flying when he was shot down? Context: On May 1, 1960, a U.S. one-man U-2 spy plane was reportedly shot down at high altitude over Soviet Union airspace. The flight was made to gain photo intelligence before the scheduled opening of an EastWest summit conference, which had been scheduled in Paris, 15 days later. Captain Francis Gary Powers had bailed out of his aircraft and was captured after parachuting down onto Russian soil. Four days after Powers disappeared, the Eisenhower Administration had NASA issue a very detailed press release noting that an aircraft had "gone missing" north of Turkey. It speculated that the pilot might have fallen unconscious while the autopilot was still engaged, and falsely claimed that "the pilot reported over the emergency frequency that he was experiencing oxygen difficulties."

Answer: Soviet Union airspace

Problem: Extract the answer to the question from the following context. Question: What was the purpose of Hayek's creation? Context: Hayek had made contact with many at the U. of Chicago in the 1940s, with Hayek's The Road to Serfdom playing a seminal role in transforming how Milton Friedman and others understood how society works. Hayek conducted a number in influential faculty seminars while at the U. of Chicago, and a number of academics worked on research projects sympathetic to some of Hayek's own, such as Aaron Director, who was active in the Chicago School in helping to fund and establish what became the "Law and Society" program in the University of Chicago Law School. Hayek, Frank Knight, Friedman and George Stigler worked together in forming the Mont Pelerin Society, an international forum for libertarian economists. Hayek and Friedman cooperated in support of the Intercollegiate Society of Individualists, later renamed the Intercollegiate Studies Institute, an American student organisation devoted to libertarian ideas.

A: international forum for libertarian economists

Problem: Given the question: Extract the answer to the question from the following context. Question: Why would someone prefer to operate a DC motor using DC power? Context: Operating at normal power line frequencies, universal motors are often found in a range less than 1000 watts. Universal motors also formed the basis of the traditional railway traction motor in electric railways. In this application, the use of AC to power a motor originally designed to run on DC would lead to efficiency losses due to eddy current heating of their magnetic components, particularly the motor field pole-pieces that, for DC, would have used solid (un-laminated) iron and they are now rarely used.
++++++++++++++++++++++++++++++++
The answer is:
efficiency losses

input question: Extract the answer to the question from the following context. Question: What is the growth goal for public transport set by Melbourne's government? Context: Melbourne has an integrated public transport system based around extensive train, tram, bus and taxi systems. Flinders Street Station was the world's busiest passenger station in 1927 and Melbourne's tram network overtook Sydney's to become the world's largest in the 1940s, at which time 25% of travellers used public transport but by 2003 it had declined to just 7.6%. The public transport system was privatised in 1999, symbolising the peak of the decline. Despite privatisation and successive governments persisting with auto-centric urban development into the 21st century, there have since been large increases in public transport patronage, with the mode share for commuters increasing to 14.8% and 8.4% of all trips. A target of 20% public transport mode share for Melbourne by 2020 was set by the state government in 2006. Since 2006 public transport patronage has grown by over 20%.???
output answer: 20% public transport mode share for Melbourne by 2020

input question: Extract the answer to the question from the following context. Question: In addition to astronomy and mathematics, what is one other accomplishment achieved by American civilizations? Context: According to both indigenous American and European accounts and documents, American civilizations at the time of European encounter had achieved many accomplishments. For instance, the Aztecs built one of the largest cities in the world, Tenochtitlan, the ancient site of Mexico City, with an estimated population of 200,000. American civilizations also displayed impressive accomplishments in astronomy and mathematics. The domestication of maize or corn required thousands of years of selective breeding.???
output answer:
domestication of maize or corn
