Student A:In the early 1960s, the Nashville sound began to be challenged by the rival Bakersfield sound on the country side and by the British Invasion on the pop side; compounding these problems were the sudden deaths, in separate airplane crashes, of Patsy Cline and Jim Reeves, two of the Nashville Sound's biggest stars. Nashville's pop song structure became more pronounced and it morphed into what was called Countrypolitan-a smoother sound typified through the use of lush string arrangements with a real orchestra and often, background vocals provided by a choir. Countrypolitan was aimed straight at mainstream markets and it sold well throughout the later 1960s into the early 1970s. Among the architects of this sound were producers Billy Sherrill (who was instrumental in shaping Tammy Wynette's early career) and Glenn Sutton. Artists who typified the countrypolitan sound initially included Wynette, Glen Campbell (who recorded in Hollywood and not Nashville), Lynn Anderson, Charlie Rich, and Charley Pride, the latter being a rare example of a top-selling African-American country performer.

Student A:Armed conflict began in 1775. In 1776, the Second Continental Congress declared a new, independent nation: the United States of America. Led by General George Washington, it won the Revolutionary War with large support from France. The peace treaty of 1783 gave the new nation the land east of the Mississippi River (except Canada and Florida). The Articles of Confederation established a central government, but it was ineffectual at providing stability, as it could not collect taxes and had no executive officer. A convention in 1787 wrote a new Constitution that was adopted in 1789. In 1791, a Bill of Rights was added to guarantee inalienable rights. With Washington as the first president and Alexander Hamilton his chief adviser, a strong central government was created. Purchase of the Louisiana Territory from France in 1803 doubled the size of the United States. A second and final war with Britain was fought in 1812, which solidified national pride.
