Input: Read this: The development of the Bronx is directly connected to its strategic location between New England and New York (Manhattan). Control over the bridges across the Harlem River plagued the period of British colonial rule. Kingsbridge, built in 1693 where Broadway reached the Spuyten Duyvil Creek, was a possession of Frederick Philipse, lord of Philipse Manor. The tolls were resented by local farmers on both sides of the creek. In 1759, the farmers led by Jacobus Dyckman and Benjamin Palmer built a "free bridge" across the Harlem River which led to the abandonment of tolls altogether.
Question: Why did farmers build a bridge over the Harlem River?

Output: tolls were resented

Input: Read this: This Act clearly demarcated borders between the Crown and the Company. After this point, the Company functioned as a regularised subsidiary of the Crown, with greater accountability for its actions and reached a stable stage of expansion and consolidation. Having temporarily achieved a state of truce with the Crown, the Company continued to expand its influence to nearby territories through threats and coercive actions. By the middle of the 19th century, the Company's rule extended across most of India, Burma, Malaya, Singapore, and British Hong Kong, and a fifth of the world's population was under its trading influence. In addition, Penang, one of the states in Malaya, became the fourth most important settlement, a presidency, of the Company's Indian territories.
Question: When EIC became more like a regularised subsidiary did they have greater or less accountability to Japan?

Output: unanswerable

Input: Read this: BeiDou-1 is an experimental regional navigation system, which consists of four satellites (three working satellites and one backup satellite). The satellites themselves were based on the Chinese DFH-3 geostationary communications satellite and had a launch weight of 1,000 kilograms (2,200 pounds) each.
Question: Which navigational system is regional and consists of five satellites?

Output: unanswerable

Input: Read this: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Question: How high is the continent of Antarctica above sea level?

Output:
3,000 m
