Input: Question: What is the current population of the town in North Carolina with Ervin calls home? Passage 1: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.
 Passage 2:Gorham's Rangers was one of the most famous and effective ranger units raised in the colonial North America. Formed by John Gorham, the unit served as the prototype for many subsequent ranger forces, including the better known Rogers' Rangers. The unit started out as a Massachusetts provincial auxiliary company, which means it was not part of the province's normal militia system. Recruited in the summer of 1744 at the start of King George's War, Governor William Shirley ordered the unit raised as reinforcements for the then-besieged British garrison at Fort Anne in Annapolis Royal. Over the next eight years the unit proved remarkably effective at suppressing Acadian and Mi'kmaq resistance to British rule in Nova Scotia and helped to both expand and secure the British sphere of influence in the region. Initially a sixty-man all-Indian company led by British colonial officers, the original Native American members of the unit were gradually replaced by Anglo-Americans and recent Scots and Irish immigrants and were a minority in the unit by the mid-1750s. The company were reconnaissance experts as well as renowned for their expertise at both water-borne operations and frontier guerrilla warfare. They were known for surprise amphibious raids on Acadian and Mi'kmaq coastal or riverine settlements, using large whaleboats, which carried between ten and fifteen rangers each. This small unit was the main British military force defending Nova Scotia from 1744 to 1749. The company became part of the British army and was expanded during the Seven Years' War and went on to play an important role in fighting in Nova Scotia as well as participating in many of the important campaigns of the war, particularly distinguishing itself at the Siege of Quebec in 1759.
 Passage 3:He tied the UT freshman record for rebounds in a game (LaSalle Thompson, 1979–80) with 17 boards at Texas Tech. He recorded a team-high of eight double-doubles, and pulled down 10 or more rebounds in a game 10 times. His put-back of a Kris Clack miss with 15 seconds left proved to be the game-winner in UT's 81-80 Big Monday victory at Texas A&M. Mihm got a piece of Rayford Young's last-second shot to preserve an 82-80 win at Texas Tech, he has hit a pair of free throws with eight seconds left to provide the final margin in an 86-83 UT win over Texas Tech in the first round of the Big 12 Tournament. He blocked at least one shot in 29 of 31 games, Mihm would miss the first month of practice (his foot was in a plastic boot for three weeks) while recovering from a mild stress injury in his right foot. He was limited to four practices prior to the season opener.
