In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

[Q]: Question: How long is the fault that lies to the east of Ice Mountain? Passage:Ice Mountain is an arc-shaped forested ridge of the Allegheny Mountains, part of the Ridge-and-valley Appalachians. It is above mean sea level at its summit. Ice Mountain is a large mass of Devonian Oriskany (Ridgeley) sandstone and Marcellus shale with numerous bare rock slopes and vertical cliffs. Ice Mountain lies on the west side of the Timber Mountain anticline and to the west of North Mountain fault, which places it on the Martinsburg allochthonous sheet. Ice Mountain is situated along North River and is known for the several hundred yards of ice that form at its base all year long. At its southern end overlooking the community of North River Mills is located Raven Rocks, a set of stone chimney outcrops. Raven Rocks is in height above mean sea level with vertical cliffs measuring nearly in height. Raven Rocks were named because of the presence of ravens during pioneer days. The present Raven Rocks is the remaining vestige of a once towering cliff that overlooked the North River. Geologically, Ice Mountain is a northern extension of North River Mountain.

[Q]: Question: In what year was CIA pilot Francis Gary Powers born? Passage:Strategic Air Command was formed by the United States Air Force after World War II to provide an active defense against any surprise attack by the Soviet Union. Though it had been an ally against Germany and Japan during World War II, by 1948 the Soviet Union showed a propensity to instigate problems with Britain, France and the United States. In August 1949, the Soviet Union detonated its first nuclear weapon and by the early 1950s had detonated a hydrogen bomb. The war of words between the two superpowers escalated during 1950s and 1960s into a nuclear arms race. By 1970 the United States was using a "Triad Defense System" composed of nuclear submarines armed with nuclear missiles, land based intercontinental ballistic missiles with nuclear warheads and bombers capable of delivering hydrogen bombs on enemy targets. The Boeing B-52 Stratofortress bomber had been designed in the early 1950s by Boeing Aircraft Company to give the United States Air Force the capability of delivering nuclear weapons far inside the territory of Soviet Russia. The planes were to fly at high altitude with enough fuel to hit their target. In May 1960, the Soviet Union made known its capability to shoot such high altitude planes out of the sky by using a surface to air missile to strike CIA pilot Francis Gary Powers' U-2 spy plane over Russian territory. From that point on, the high-altitude B-52 had to be modified to conduct missions at low level, something it was not intended to be.

[Q]: Question: Who founded the club that issued many of Booth's pamphlets? Passage:During the American Civil War (1861–1865), Booth translated the works of eminent French writers in favor of the cause of the Union. In rapid succession appeared translations of: Agénor Gasparin's Uprising of a Great People and America before Europe (New York, 1861), Édouard René de Laboulaye's Paris in America (New York, 1865), and Augustin Cochin's Results of Emancipation and Results of Slavery (Boston, 1862). For this work she received praise and encouragement from U.S. President Abraham Lincoln, U.S. Senator Charles Sumner, and other statesmen. During the entire war she maintained a correspondence with Cochin, Gasparin, Laboulaye, Henri Martin, Charles Forbes René de Montalembert, and other European sympathizers with the Union. At that time, she also translated the Countess de Gasparin's Vesper, Camille, and Human Sorrows, and Count Gasparin's Happiness. Documents forwarded to her by French friends of the Union were translated and published in pamphlets, issued by the Union League Club, or printed in the New York journals. Booth translated Henri Martin's History of France. The two volumes treating of The Age of Louis XIV were issued in 1864, and two others, the last of the seventeen volumes of the original work, in 1866 under the title of The Decline of the French Monarchy. It was intended to follow these with the other volumes from the beginning, but, although she translated two others, the enterprise was abandoned for lack of success, and no more were printed. Her translation of Martin's abridgment of his History of France appeared in 1880. She also translated Laboulaye's Fairy Book, Jean Macé's Fairy Tales and Blaise Pascal's Lettres provinciales (Provincial Letters). The "Uprising of a Great People", was followed rapidly by Gasparin's "America Before Europe," by Laboulaye's "Paris in America," and two volumes by Augustin Cochin, " Results of Emancipation" and "Results of Slavery." Cochin's work attracted even more attention than Gasparin's had done. She received hundreds of appreciative letters from the leading Republican statesman — Henry Winter Davis, Senator Doolittle, Galusha A. Grow, Dr. Lieber, Dr. Bell, the president of the Sanitary Commission, and a host of others, among them George Sumner, Cassius M. Clay, and Attorney-General Speed, Charles Sumner writing her that Cochin's work had been of more value to the cause "than the Numidian cavalry to Hannibal." In the meantime, she pursued her translations as before, adding to her list Laboulaye's "Fairy Tales," and Jean Mace's " Fairy Book," and several of the religious works of the Count and Countess do Gasparin, "Happiness" by the former, and "Camille," " Vesper," and " Human Sorrows " by the latter. Her translations in all number nearly forty volumes. She had thought of adding to this number, at the request of Mr. James T. Fields, an abridgment of George Sand's voluminous "Histoire de ma Vie". Circumstances, however, prevented the completion of the work.
