The term "high fidelity" was coined in the 1920s by some manufacturers of radio receivers and phonographs to differentiate their better-sounding products claimed as providing "perfect" sound reproduction. The term began to be used by some audio engineers and consumers through the 1930s and 1940s. After 1949 a variety of improvements in recording and playback technologies, especially stereo recordings, which became widely available in 1958, gave a boost to the "hi-fi" classification of products, leading to sales of individual components for the home such as amplifiers, loudspeakers, phonographs, and tape players. High Fidelity and Audio were two magazines that hi-fi consumers and engineers could read for reviews of playback equipment and recordings.

Like the Speaker of the House, the Minority Leaders are typically experienced lawmakers when they win election to this position. When Nancy Pelosi, D-CA, became Minority Leader in the 108th Congress, she had served in the House nearly 20 years and had served as minority whip in the 107th Congress. When her predecessor, Richard Gephardt, D-MO, became minority leader in the 104th House, he had been in the House for almost 20 years, had served as chairman of the Democratic Caucus for four years, had been a 1988 presidential candidate, and had been majority leader from June 1989 until Republicans captured control of the House in the November 1994 elections. Gephardt's predecessor in the minority leadership position was Robert Michel, R-IL, who became GOP Leader in 1981 after spending 24 years in the House. Michel's predecessor, Republican John Rhodes of Arizona, was elected Minority Leader in 1973 after 20 years of House service.

This apparatus may be made of hemp or a synthetic material which retains the qualities of lightness and suppleness. Its length is in proportion to the size of the gymnast. The rope should, when held down by the feet, reach both of the gymnasts' armpits. One or two knots at each end are for keeping hold of the rope while doing the routine. At the ends (to the exclusion of all other parts of the rope) an anti-slip material, either coloured or neutral may cover a maximum of 10 cm (3.94 in). The rope must be coloured, either all or partially and may either be of a uniform diameter or be progressively thicker in the center provided that this thickening is of the same material as the rope. The fundamental requirements of a rope routine include leaps and skipping. Other elements include swings, throws, circles, rotations and figures of eight. In 2011, the FIG decided to nullify the use of rope in rhythmic gymnastic competitions.

What other requirement is there for the rope?
Answer:
The rope must be coloured, either all or partially and may either be of a uniform diameter or be progressively thicker in the center
