Other major bluegrass mandolinists who emerged in the early 1950s and are still active include Jesse McReynolds (of Jim and Jesse) who invented a syncopated banjo-roll-like style called crosspicking—and Bobby Osborne of the Osborne Brothers, who is a master of clarity and sparkling single-note runs. Highly respected and influential modern bluegrass players include Herschel Sizemore, Doyle Lawson, and the multi-genre Sam Bush, who is equally at home with old-time fiddle tunes, rock, reggae, and jazz. Ronnie McCoury of the Del McCoury Band has won numerous awards for his Monroe-influenced playing. The late John Duffey of the original Country Gentlemen and later the Seldom Scene did much to popularize the bluegrass mandolin among folk and urban audiences, especially on the east coast and in the Washington, D.C. area.
 Who won no awards for his Monroe influenced music?

That said, the score does not provide complete and exact instructions on how to perform a historical work. Even if the tempo is written with an Italian instruction (e.g., Allegro), we do not know exactly how fast the piece should be played. As well, in the Baroque era, many works that were designed for basso continuo accompaniment do not specify which instruments should play the accompaniment or exactly how the chordal instrument (harpsichord, lute, etc.) should play the chords, which are not notated in the part (only a figured bass symbol beneath the bass part is used to guide the chord-playing performer). The performer and/or the conductor have a range of options for musical expression and interpretation of a scored piece, including the phrasing of melodies, the time taken during fermatas (held notes) or pauses, and the use (or choice not to use) of effects such as vibrato or glissando (these effects are possible on various stringed, brass and woodwind instruments and with the human voice).
Vibrato and glissando are possible on stringed, brass, woodwind and what other style instrument?
A: the human voice

The goalkeepers are the only players allowed to touch the ball with their hands or arms while it is in play and only in their penalty area. Outfield players mostly use their feet to strike or pass the ball, but may also use their head or torso to do so instead. The team that scores the most goals by the end of the match wins. If the score is level at the end of the game, either a draw is declared or the game goes into extra time and/or a penalty shootout depending on the format of the competition. The Laws of the Game were originally codified in England by The Football Association in 1863. Association football is governed internationally by the International Federation of Association Football (FIFA; French: Fédération Internationale de Football Association), which organises World Cups for both men and women every four years.
What year did the Football Association remove The Laws of the Game?

The geologic record of the Proterozoic (2,500 to 541 million years ago) is more complete than that for the preceding Archean. In contrast to the deep-water deposits of the Archean, the Proterozoic features many strata that were laid down in extensive shallow epicontinental seas; furthermore, many of these rocks are less metamorphosed than Archean-age ones, and plenty are unaltered. Study of these rocks show that the eon featured massive, rapid continental accretion (unique to the Proterozoic), supercontinent cycles, and wholly modern orogenic activity. Roughly 750 million years ago, the earliest-known supercontinent Rodinia, began to break apart. The continents later recombined to form Pannotia, 600–540 Ma.
What era came before the Proterozoic era?
A:
Archean
