Input: Read this: A watt balance is an instrument for comparing two powers, one of which is measured in SI watts and the other of which is measured in conventional electrical units. From the definition of the conventional watt W90, this gives a measure of the product KJ2RK in SI units, where RK is the von Klitzing constant which appears in the quantum Hall effect. If the theoretical treatments of the Josephson effect and the quantum Hall effect are valid, and in particular assuming that RK = h/e2, the measurement of KJ2RK is a direct determination of the Planck constant.
Question: What value does RM represent?

Output: unanswerable


Input: Read this: When World War II started, tonnage levels at the port decreased and shipping activities were suspended; however, the war did provide economic benefits for the city. Petrochemical refineries and manufacturing plants were constructed along the ship channel because of the demand for petroleum and synthetic rubber products by the defense industry during the war. Ellington Field, initially built during World War I, was revitalized as an advanced training center for bombardiers and navigators. The Brown Shipbuilding Company was founded in 1942 to build ships for the U.S. Navy during World War II. Due to the boom in defense jobs, thousands of new workers migrated to the city, both blacks and whites competing for the higher-paying jobs. President Roosevelt had established a policy of non-discrimination for defense contractors, and blacks gained some opportunities, especially in shipbuilding, although not without resistance from whites and increasing social tensions that erupted into occasional violence. Economic gains of blacks who entered defense industries continued in the postwar years.
Question: hat was the policy created by the Vice-President due to the boom in defense jobs?

Output: unanswerable


Input: Read this: Since 1973 Plymouth has been supplied water by South West Water. Prior to the 1973 take over it was supplied by Plymouth County Borough Corporation. Before the 19th century two leats were built in order to provide drinking water for the town. They carried water from Dartmoor to Plymouth. A watercourse, known as Plymouth or Drake's Leat, was opened on 24 April 1591 to tap the River Meavy. The Devonport Leat was constructed to carry fresh drinking water to the expanding town of Devonport and its ever growing dockyard. It was fed by three Dartmoor rivers: The West Dart, Cowsic and Blackabrook. It seems to have been carrying water since 1797, but it was officially completed in 1801. It was originally designed to carry water to Devonport town, but has since been shortened and now carries water to Burrator Reservoir, which feeds most of the water supply of Plymouth. Burrator Reservoir is located about 5 miles (8 km) north of the city and was constructed in 1898 and expanded in 1928.
Question: When did Drake's Leat open?

Output: 24 April 1591


Input: Read this: Participation in the Premier League by some Scottish or Irish clubs has sometimes been discussed, but without result. The idea came closest to reality in 1998, when Wimbledon received Premier League approval to relocate to Dublin, Ireland, but the move was blocked by the Football Association of Ireland. Additionally, the media occasionally discusses the idea that Scotland's two biggest teams, Celtic and Rangers, should or will take part in the Premier League, but nothing has come of these discussions.
Question: In which year did a Premier League team consider relocating to Ireland?

Output:
1998
