Input: Consider Input: Question: How many year does the person who appoints governors in India serve per term? Passage:In the Republic of India, a governor is the constitutional head of each of the twenty-eight states. The governor is appointed by the President of India for a term of five years, and holds office at the President's pleasure. The governor is de jure head of the state government; all its executive actions are taken in the governor's name. However, the governor must act on the advice of the popularly elected council of ministers, headed by the chief minister, which thus holds de facto executive authority at the state-level. The Constitution of India also empowers the governor to act upon his or her own discretion, such as the ability to appoint or dismiss a ministry, recommend President's rule, or reserve bills for the President's assent. Over the years, the exercise of these discretionary powers have given rise to conflict between the elected chief minister and the union governmentappointed governor.
Links: a. Government of India b. President of India c. Ministry (collective executive) d. Constitution of India

Output: b

Input: Consider Input: Question: How many days did the battle the Baron was killed in last? Passage:While they were travelling to Europe in 1914, the First World War broke out and the ship carrying Von Wolf and his wife was diverted to Rio de Janeiro. Jayta Humphreys had retained her American citizenship and found passage to Europe on a Dutch ship; legend has it the Baron had to travel disguised as a woman. On arrival in Europe the Baron rejoined the German army, and was killed at the Battle of the Somme in 1916, just two weeks after signing up. His wife could not bring herself to return to Namibia alone and never again laid claim to the majestic castle. She stayed on the coast of the Tegernmeer in Bavaria (since her stepfather had been appointed consul general in Munich), before settling in the late 1930s in Zurich, where she met and married Erich Schlemmer, the consul general of Siam. After the Von Wolfs left South Africa, their friend Max Count von Luttichau was given executorship of the farm, but it declared bankruptcy shortly after World War I, and since the South African government paid no compensation for this or several wartime raids, the house was sold for 7,500 to the Swedish Murrmann family. The new owner died shortly after his arrival and his son was killed in World War II, following which the castle was sold for 25,000 pounds to the private company Duwisib Pty Ltd and the rest of the land was divided and sold off. Jayta returned to the US to stay with her parents in Summit, New Jersey. Several changes in ownership later, the castle was acquired by the government in 1979 and extensively refurbished in 1991.

Input: Consider Input: Question: Which of the nearby counties of the "Tennessee Valley" has the largest population? Passage:According to the United States Census 2013 estimate, the combined statistical area has a population of 1,313,105. It is the 42nd largest population sub-region in the United States, and the largest population region in Alabama, constituting roughly 1/4 of the state's population. It is the largest population region in Central Alabama. The northern counties of the metropolitan area overlap North Alabama known locally as the "Tennessee Valley" making it the largest metropolitan area in that region as well. Nearby counties Tuscaloosa, Etowah, and Calhoun, while not officially a part of Greater Birmingham, contribute significantly to the region's economy. The Birmingham media market covers these counties as well. Birmingham is part of the Piedmont Atlantic Megaregion containing an estimated 19 million people, while many residents also consider themselves part of the Deep South. It is classified as Southeast by the U.S. Census and also falls in the geographic area of the Upland South due to its location at the southern terminus of the Appalachian foothills. The entire MSA and CSA are within the congressional Appalachian Regional Commission's definition of Appalachia.
Links: a. Tuscaloosa County, Alabama b. Appalachia c. Southeastern United States d. Piedmont Atlantic Megaregion
Output: a
