QUES: The mandolin orchestras never completely went away, however. In fact, along with all the other musical forms the mandolin is involved with, the mandolin ensemble (groups usually arranged like the string section of a modern symphony orchestra, with first mandolins, second mandolins, mandolas, mandocellos, mando-basses, and guitars, and sometimes supplemented by other instruments) continues to grow in popularity. Since the mid-nineties, several public-school mandolin-based guitar programs have blossomed around the country, including Fretworks Mandolin and Guitar Orchestra, the first of its kind. The national organization, Classical Mandolin Society of America, founded by Norman Levine, represents these groups. Prominent modern mandolinists and composers for mandolin in the classical music tradition include Samuel Firstman, Howard Fry, Rudy Cipolla, Dave Apollon, Neil Gladd, Evan Marshall, Marilynn Mair and Mark Davis (the Mair-Davis Duo), Brian Israel, David Evans, Emanuil Shynkman, Radim Zenkl, David Del Tredici and Ernst Krenek.
Who are modern mandolinists and composers?

ANS: Samuel Firstman, Howard Fry, Rudy Cipolla

QUES: According to the United States Census Bureau, the city has a total area of 656.3 square miles (1,700 km2); this comprises 634.0 square miles (1,642 km2) of land and 22.3 square miles (58 km2) of water. The Piney Woods is north of Houston. Most of Houston is located on the gulf coastal plain, and its vegetation is classified as temperate grassland and forest. Much of the city was built on forested land, marshes, swamp, or prairie which resembles the Deep South, and are all still visible in surrounding areas. Flatness of the local terrain, when combined with urban sprawl, has made flooding a recurring problem for the city. Downtown stands about 50 feet (15 m) above sea level, and the highest point in far northwest Houston is about 125 feet (38 m) in elevation. The city once relied on groundwater for its needs, but land subsidence forced the city to turn to ground-level water sources such as Lake Houston, Lake Conroe and Lake Livingston. The city owns surface water rights for 1.20 billion gallons of water a day in addition to 150 million gallons a day worth of groundwater.
 What kind of weather event is a not recurring problem for Houston?

ANS: unanswerable

QUES: A ballot initiative in Colorado, known as Amendment 36, would have changed the way in which the state apportions its electoral votes. Rather than assigning all 9 of the state's electors to the candidate with a plurality of popular votes, under the amendment Colorado would have assigned presidential electors proportionally to the statewide vote count, which would be a unique system (Nebraska and Maine assign electoral votes based on vote totals within each congressional district). Detractors claimed that this splitting would diminish Colorado's influence in the Electoral College, and the amendment ultimately failed, receiving only 34% of the vote.
What did Amendment 36 change in Nebraska?

ANS: unanswerable

QUES: There are many non-incandescent light sources, such as the fluorescent lamp, high-intensity discharge lamps and LED lamps, which have higher luminous efficiency, and some have been designed to be retrofitted in fixtures for incandescent lights. These devices produce light by luminescence. These lamps produce discrete spectral lines and do not have the broad "tail" of invisible infrared emissions. By careful selection of which electron energy level transitions are used, and fluorescent coatings which modify the spectral distribution, the spectrum emitted can be tuned to mimic the appearance of incandescent sources, or other different color temperatures of white light. Due to the discrete spectral lines rather than a continuous spectrum, the light is not ideal for applications such as photography and cinematography.
Which lights have lower luminous efficiency?

unanswerable
