Input: Read this: When Cowan Powers and his family recorded their old-time music from 1924-1926, his daughter Orpha Powers was one of the earliest known southern-music artists to record with the mandolin. By the 1930s, single mandolins were becoming more commonly used in southern string band music, most notably by brother duets such as the sedate Blue Sky Boys (Bill Bolick and Earl Bolick) and the more hard-driving Monroe Brothers (Bill Monroe and Charlie Monroe). However, the mandolin's modern popularity in country music can be directly traced to one man: Bill Monroe, the father of bluegrass music. After the Monroe Brothers broke up in 1939, Bill Monroe formed his own group, after a brief time called the Blue Grass Boys, and completed the transition of mandolin styles from a "parlor" sound typical of brother duets to the modern "bluegrass" style. He joined the Grand Ole Opry in 1939 and its powerful clear-channel broadcast signal on WSM-AM spread his style throughout the South, directly inspiring many musicians to take up the mandolin. Monroe famously played Gibson F-5 mandolin, signed and dated July 9, 1923, by Lloyd Loar, chief acoustic engineer at Gibson. The F-5 has since become the most imitated tonally and aesthetically by modern builders.

Input: Read this: Cotton is used to make a number of textile products. These include terrycloth for highly absorbent bath towels and robes; denim for blue jeans; cambric, popularly used in the manufacture of blue work shirts (from which we get the term "blue-collar"); and corduroy, seersucker, and cotton twill. Socks, underwear, and most T-shirts are made from cotton. Bed sheets often are made from cotton. Cotton also is used to make yarn used in crochet and knitting. Fabric also can be made from recycled or recovered cotton that otherwise would be thrown away during the spinning, weaving, or cutting process. While many fabrics are made completely of cotton, some materials blend cotton with other fibers, including rayon and synthetic fibers such as polyester. It can either be used in knitted or woven fabrics, as it can be blended with elastine to make a stretchier thread for knitted fabrics, and apparel such as stretch jeans.
Question: For what are jeans used to make?

Output: unanswerable

Input: Read this: People with long-term pain frequently display psychological disturbance, with elevated scores on the Minnesota Multiphasic Personality Inventory scales of hysteria, depression and hypochondriasis (the "neurotic triad"). Some investigators have argued that it is this neuroticism that causes acute pain to turn chronic, but clinical evidence points the other way, to chronic pain causing neuroticism. When long-term pain is relieved by therapeutic intervention, scores on the neurotic triad and anxiety fall, often to normal levels. Self-esteem, often low in chronic pain patients, also shows improvement once pain has resolved.
Question: What shows improvement in many patients once their pain has been resolved?

Output: Self-esteem

Input: Read this: Opposition to the union mounted among some of Syria's key elements, namely the socioeconomic, political, and military elites. In response to Syria's worsening economy, which Nasser attributed to its control by the bourgeoisie, in July 1961, Nasser decreed socialist measures that nationalized wide-ranging sectors of the Syrian economy. He also dismissed Sarraj in September to curb the growing political crisis. Aburish states that Nasser was not fully capable of addressing Syrian problems because they were "foreign to him". In Egypt, the economic situation was more positive, with a GNP growth of 4.5 percent and a rapid growth of industry. In 1960, Nasser nationalized the Egyptian press, which had already been cooperating with his government, in order to steer coverage towards the country's socioeconomic issues and galvanize public support for his socialist measures.
Question: What Syrian social group opposed the UAR?

Output:
elites
