In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Input: Consider Input: What feature of airports was significantly increased in length to deal with the increase in jet aircraft traffic?, Context: Airport construction boomed during the 1960s with the increase in jet aircraft traffic. Runways were extended out to 3,000 m (9,800 ft). The fields were constructed out of reinforced concrete using a slip-form machine that produces a continual slab with no disruptions along the length. The early 1960s also saw the introduction of jet bridge systems to modern airport terminals, an innovation which eliminated outdoor passenger boarding. These systems became commonplace in the United States by the 1970s.

Output: Runways


Input: Consider Input: Who helped prepare?, Context: The Apollo astronauts were chosen from the Project Mercury and Gemini veterans, plus from two later astronaut groups. All missions were commanded by Gemini or Mercury veterans. Crews on all development flights (except the Earth orbit CSM development flights) through the first two landings on Apollo 11 and Apollo 12, included at least two (sometimes three) Gemini veterans. Dr. Harrison Schmitt, a geologist, was the first NASA scientist astronaut to fly in space, and landed on the Moon on the last mission, Apollo 17. Schmitt participated in the lunar geology training of all of the Apollo landing crews.

Output: Schmitt


Input: Consider Input: One of the Canadian MLB teams is the Toronto Blue Jays - what is the other Canadian MLB team?, Context: Several MLB teams used to play regular exhibition games during the year against nearby teams in the other major league, but regular-season interleague play has made such games unnecessary. The two Canadian MLB teams, the Toronto Blue Jays of the American League and the Montreal Expos of the National League, met annually to play the Pearson Cup exhibition game; this tradition ended when the Expos moved to Washington DC for the 2005 season. Similarly, the New York Yankees played in the Mayor's Trophy Game against various local rivals from 1946 to 1983.


Output: Montreal Expos
