Question: 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.

Question: Passage: Samuel James "Sam" Ervin Jr. (September 27, 1896April 23, 1985) was an American politician. A Democrat, he served as a U.S. Senator from North Carolina from 1954 to 1974. A native of Morganton, he liked to call himself a "country lawyer," and often told humorous stories in his Southern drawl. During his Senate career, Ervin was a legal defender of the Jim Crow laws and racial segregation, as the South's constitutional expert during the congressional debates on civil rights. Unexpectedly, he became a liberal hero for his support of civil liberties. He is remembered for his work in the investigation committees that brought down Senator Joseph McCarthy in 1954 and especially for his investigation of the Watergate scandal in 1972 that led to the resignation of Richard Nixon.

Question: Passage: When the Countess von Gleichen's brother, Francis, inherited his cousin's Marquessate of Hertford in 1870, the Queen granted her the rank and style of the daughter of a marquess by Royal Warrant of Precedence, entitling her to prefix Lady to her name. However, she continued to use her comital title until 15 December 1885, when it was gazetted in the Court Circular that the Queen had granted her permission to share, within the British Empire, her husband's princely title. Henceforth she was known as HSH Princess Victor of Hohenlohe-Langenburg, although this changed neither her legal rank nor her title in the German Empire. In accordance with the original Coburg grant, her children were also Count/Countess von Gleichen and, although granted unique precedence before the daughters and younger sons of English dukes in 1913, they never received authorisation to share their parents' princely style at the Court of St. James's, and were known by their comital title (dropping, however, the von) until George V Anglicised their style in 1917, along with the styles of members of his own family who bore German titles. Princess Victor did not live to undergo that demotion in titulature.
