Input: Read this: During a panel discussion at Harvard University's reunion for African American alumni during the 200304 academic year, two prominent black professors at the institutionLani Guinier and Henry Louis Gatespointed out an unintended effect of affirmative action policies at Harvard. They stated that only about a third of black Harvard undergraduates were from families in which all four grandparents were born into the African American community. The majority of black students at Harvard were Caribbean and African immigrants or their children, with some others the mixed-race children of biracial couples. One Harvard student, born in the South Bronx to a black family whose ancestors have been in the United States for multiple generations, said that there were so few Harvard students from the historic African American community that they took to calling themselves "the descendants" (i.e., descendants of American slaves). The reasons for this underrepresentation of historic African Americans, and possible remedies, remain a subject of debate.
Question: What portion of black Harvard undergraduates came from families in which all four grandparents were born into the Asian American community?

Output: unanswerable

Input: Read this: On October 25, 1836, construction began on the Wilmington and Raleigh Railroad to connect the port city of Wilmington with the state capital of Raleigh. In 1849 the North Carolina Railroad was created by act of the legislature to extend that railroad west to Greensboro, High Point, and Charlotte. During the Civil War, the Wilmington-to-Raleigh stretch of the railroad would be vital to the Confederate war effort; supplies shipped into Wilmington would be moved by rail through Raleigh to the Confederate capital of Richmond, Virginia.
Question: The Wilmington and Raleigh Railroad was going to connect Wilmington to what city?

Output: Raleigh

Input: Read this: During the Republic, any person who wished to hold public office had to conform to the Reformed Church and take an oath to this effect. The extent to which different religions or denominations were persecuted depended much on the time period and regional or city leaders. In the beginning, this was especially focused on Roman Catholics, being the religion of the enemy. In 17th-century Leiden, for instance, people opening their homes to services could be fined 200 guilders (a year's wage for a skilled tradesman) and banned from the city. Throughout this, however, personal freedom of religion existed and was one factor along with economic reasons in causing large immigration of religious refugees from other parts of Europe.
Question: What was one reason for the large amounts of immigration of religious refugees from other parts of Europe?

Output: personal freedom of religion

Input: Read this: In their attempt to ensure white supremacy decades after emancipation, in the early 20th century, most southern states created laws based on the one-drop rule, defining as black, persons with any known African ancestry. This was a stricter interpretation than what had prevailed in the 19th century; it ignored the many mixed families in the state and went against commonly accepted social rules of judging a person by appearance and association. Some courts called it "the traceable amount rule." Anthropologists called it an example of a hypodescent rule, meaning that racially mixed persons were assigned the status of the socially subordinate group.
Question: What is the one-drop rule?

Output:
defining as black, persons with any known African ancestry
