Example Input: In early August 2008, who was not working for the AFL, Ed Policy or David Baker?, Context: After 12 years as commissioner of the AFL, David Baker retired unexpectedly on July 25, 2008, just two days before ArenaBowl XXII; deputy commissioner Ed Policy was named interim commissioner until Baker's replacement was found. Baker explained, "When I took over as commissioner, I thought it would be for one year. It turned into 12. But now it's time."
Example Output: David Baker

Example Input: What is an exception to their role?, Context: During the ceremony of initiation, the candidate is expected to swear (usually on a volume of sacred text appropriate to his personal religious faith) to fulfil certain obligations as a Mason. In the course of three degrees, new masons will promise to keep the secrets of their degree from lower degrees and outsiders, and to support a fellow Mason in distress (as far as practicality and the law permit). There is instruction as to the duties of a Freemason, but on the whole, Freemasons are left to explore the craft in the manner they find most satisfying. Some will further explore the ritual and symbolism of the craft, others will focus their involvement on the social side of the Lodge, while still others will concentrate on the charitable functions of the lodge.
Example Output: as far as practicality and the law permit

Example Input: What did Indigenous Americans find in Africans that made them want to encourage marriage between each other?, Context: European colonists created treaties with Indigenous American tribes requesting the return of any runaway slaves. For example, in 1726, the British governor of New York exacted a promise from the Iroquois to return all runaway slaves who had joined them. This same promise was extracted from the Huron Nation in 1764, and from the Delaware Nation in 1765, though there is no record of slaves ever being returned. Numerous advertisements requested the return of African Americans who had married Indigenous Americans or who spoke an Indigenous American language. The primary exposure that Africans and Indigenous Americans had to each other came through the institution of slavery. Indigenous Americans learned that Africans had what Indigenous Americans considered 'Great Medicine' in their bodies because Africans were virtually immune to the Old-World diseases that were decimating most native populations. Because of this, many tribes encouraged marriage between the two groups, to create stronger, healthier children from the unions.
Example Output:
Africans were virtually immune to the Old-World diseases
