Input: Article: While royal assent has not been withheld in the United Kingdom since 1708, it has often been withheld in British colonies and former colonies by governors acting on royal instructions. In the United States Declaration of Independence, colonists complained that George III "has refused his Assent to Laws, the most wholesome and necessary for the public good [and] has forbidden his Governors to pass Laws of immediate and pressing importance, unless suspended in their operation till his Assent should be obtained; and when so suspended, he has utterly neglected to attend to them." Even after colonies such as Canada, Australia, New Zealand, the Union of South Africa, and Newfoundland were granted responsible government, the British government continued to sometimes advise governors-general on the granting of assent; assent was also occasionally reserved to allow the British government to examine a bill before advising the governor-general.

Now answer this question: In what year was royal assent last witheld in the UK?

Output: 1708

Input: Article: Oakland County in Metro Detroit, once rated amongst the wealthiest US counties per household, is no longer shown in the top 25 listing of Forbes magazine. But internal county statistical methods – based on measuring per capita income for counties with more than one million residents – show that Oakland is still within the top 12, slipping from the 4th-most affluent such county in the U.S. in 2004 to 11th-most affluent in 2009. Detroit dominates Wayne County, which has an average household income of about $38,000, compared to Oakland County's $62,000.

Now answer this question: What city dominates Wayne County?

Output: Detroit

Input: Article: Since the early history of the United States, Amerindians, African–Americans, and European Americans have been classified as belonging to different races. Efforts to track mixing between groups led to a proliferation of categories, such as mulatto and octoroon. The criteria for membership in these races diverged in the late 19th century. During Reconstruction, increasing numbers of Americans began to consider anyone with "one drop" of known "Black blood" to be Black, regardless of appearance.3 By the early 20th century, this notion was made statutory in many states.4 Amerindians continue to be defined by a certain percentage of "Indian blood" (called blood quantum). To be White one had to have perceived "pure" White ancestry. The one-drop rule or hypodescent rule refers to the convention of defining a person as racially black if he or she has any known African ancestry. This rule meant that those that were mixed race but with some discernible African ancestry were defined as black. The one-drop rule is specific to not only those with African ancestry but to the United States, making it a particularly African-American experience.

Now answer this question: What did efforts to track mixing between different groups lead to?

Output:
a proliferation of categories
