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.

Passage: The only nation to deploy female combat troops in substantial numbers was Russia. From the onset, female recruits either joined the military in disguise or were tacitly accepted by their units. The most prominent were a contingent of front-line light cavalry in a Cossack regiment commanded by a female colonel, Alexandra Kudasheva. Others included Maria Bochkareva, who was decorated three times and promoted to senior NCO rank, while The New York Times reported that a group of twelve schoolgirls from Moscow had enlisted together disguised as young men. In 1917, the Provisional Government raised a number of "Women's Battalions", with Bochkareva given an officer's commission in command. They were disbanded before the end of the year. In the later Russian Civil War, they fought both for the Bolsheviks (infantry) and the White Guard.
