question:
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.

Question: Who was the leader of Solidarity in 1991? Passage:The 1991 Polish parliamentary election was held on 27 October 1991 to elect deputies to both houses of the National Assembly. The 1991 election was notable on several counts. It was the first parliamentary election to be held since the formation of the Third Republic, the first entirely free and competitive legislative election since the fall of communism, the first completely free legislative election of any sort since 1928, and only the fifth completely free election in all of Polish history. Due to the collapse of the Solidarity movement's political wing, the 1991 election saw deep political fragmentation, with a multitude of new parties and alliances emerging in its wake. Low voting thresholds within individual constituencies, along with a five percent national threshold allocated to a small portion of the Sejm, additionally contributed to party fragmentation. As a result, 29 political parties gained entry into the Sejm and 22 in the Senate, with no party holding a decisive majority. Two months of intense coalition negotiations followed, with Jan Olszewski of the Centre Agreement forming a minority government along with the Christian National Union, remnants of the broader Center Civic Alliance, and the Peasants' Agreement, with conditional support from Polish People's Party, Solidarity and other minor parties.
