Problem: Military history of the United States:

After the Civil War, population expansion, railroad construction, and the disappearance of the buffalo herds heightened military tensions on the Great Plains. Several tribes, especially the Sioux and Comanche, fiercely resisted confinement to reservations. The main role of the Army was to keep indigenous peoples on reservations and to end their wars against settlers and each other, William Tecumseh Sherman and Philip Sheridan were in charge. A famous victory for the Plains Nations was the Battle of the Little Big Horn in 1876, when Col. George Armstrong Custer and two hundred plus members of the 7th Cavalry were killed by a force consisting of Native Americans from the Lakota, Northern Cheyenne, and Arapaho nations. The last significant conflict came in 1891.

Problem: In 1940, Jeannette Rankin had once again been elected to Congress, and in 1941, as she did in 1917, she voted against the United States' declaration of war. This time she was the only vote against the war, and in the wake of public outcry over her vote, she required police protection for a time. Other pacifists tended to be those from "peace churches" who generally opposed war. Many individuals from throughout the U.S. who claimed conscientious objector status were sent to Montana during the war as smokejumpers and for other forest fire-fighting duties.
When did she vote a second time against war?

Answer: 1941

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
During the 1988 presidential election, George H. W. Bush (Yale '48) derided Michael Dukakis for having "foreign-policy views born in Harvard Yard's boutique". When challenged on the distinction between Dukakis's Harvard connection and his own Yale background, he said that, unlike Harvard, Yale's reputation was "so diffuse, there isn't a symbol, I don't think, in the Yale situation, any symbolism in it" and said Yale did not share Harvard's reputation for "liberalism and elitism". In 2004 Howard Dean stated, "In some ways, I consider myself separate from the other three (Yale) candidates of 2004. Yale changed so much between the class of '68 and the class of '71. My class was the first class to have women in it; it was the first class to have a significant effort to recruit African Americans. It was an extraordinary time, and in that span of time is the change of an entire generation".
How did George H. W. Bush describe Harvard's reputation?
A: liberalism and elitism

Context and question: Throughout most of his career, Athanasius had many detractors. Classical scholar Timothy Barnes relates contemporary allegations against Athanasius: from defiling an altar, to selling Church grain that had been meant to feed the poor for his own personal gain, and even violence and murder to suppress dissent. Athanasius used "Arian" to describe both followers of Arius, and as a derogatory polemical term for Christians who disagreed with his formulation of the Trinity. Athanasius called many of his opponents "Arian", except for Miletus.
He was accused of selling grain for what reason?
Answer: his own personal gain

Problem: Premier League:

The TV rights agreement between the Premier League and Sky has faced accusations of being a cartel, and a number of court cases have arisen as a result. An investigation by the Office of Fair Trading in 2002 found BSkyB to be dominant within the pay TV sports market, but concluded that there were insufficient grounds for the claim that BSkyB had abused its dominant position. In July 1999 the Premier League's method of selling rights collectively for all member clubs was investigated by the UK Restrictive Practices Court, who concluded that the agreement was not contrary to the public interest.

Who investigated the agreement between the Premier League and Sky in 2002?

the Office of Fair Trading
