Re: General Quiz

Hi bobbym,

The Answer #5695 (Maginot Line) is correct! Excellent!

#5697. Name the term / phrase - Definition given by Oxford Dictionary - Energy fueled into ways that do not use up natural resources or harm the environment.

#5698. Name a type of waste which can be broken down, in a matter of weeks or few months, into its base compounds by micro-organisms and other living things, regardless of what those compounds may be. These can be commonly found in municipal solid waste  as green waste, food waste, paper waste, and these plastics. Other such include human waste, manure, sewage, sewage sludge and slaughterhouse waste. In the absence of oxygen, much of this waste will decay to methane by anaerobic digestion.

Re: General Quiz

Hi bobbym,

Both the Answers, #5699 and #5700, are correct! Stupendous!

#5701. Name the element  produced entirely by cosmic ray spallation and not by stellar nucleosynthesis it is a low-abundance element in both the Solar system and the Earth's crust. It is concentrated on Earth by the water-solubility of its more common naturally occurring compounds. The largest proven deposits of this element are in Turkey, which is also the largest producer of these minerals. The primary use of this element is to make these filaments, which are used in a similar way to carbon fibers in some high-strength materials.


#5702.  Name the chemical element with atomic number 48. This soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it prefers oxidation state +2 in most of its compounds and like mercury it shows a low melting point compared to transition metals. The metal and its congeners (congeners are related chemical substances "related to each other by origin, structure, or function") are not always considered transition metals, in that they do not have partly filled d or f electron shells in the elemental or common oxidation states. The average concentration of the metal in Earth's crust is between 0.1 and 0.5 parts per million (ppm).

#5703. Name the  American lawyer and author  (July 17, 1889 – March 11, 1970). Though best known for the Perry Mason series of detective stories, he wrote numerous other novels and shorter pieces, as well as a series of non-fiction books, mostly narrations of his travels through Baja California and other regions in Mexico. The best-selling American author of the 20th century at the time of his death, he also published under numerous pseudonyms, including A.A. Fair, Kyle Corning, Charles M. Green, Carleton Kendrake, Charles J. Kenny, Les Tillray and Robert Parr.

#5704.  Name the short story by American author Washington Irving published in 1819 as well as the name of the story's fictional protagonist. Written while he was living in Birmingham, England, it was part of a collection entitled 'The Sketch Book of Geoffrey Crayon, Gent'. Although the story is set in New York's Catskill Mountains, he later admitted, "When I wrote the story, I had never been on the Catskills'.

At 397,929 square miles (1,030,631 square kilometers),90% of which is desert, Mauritania is the world's 29th-largest country (after Bolivia). It is comparable in size to Egypt. It lies mostly between latitudes 14° and 26°N, and longitudes 5° and 17°W (small areas are east of 5° and west of 17°).

#5711.  Name the compound of two elements. It is a III-V direct bandgap semiconductor with a zinc blende crystal structure. It is used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells and optical windows. Some electronic properties of it are superior to those of silicon. It has a higher saturated electron velocity and higher electron mobility, allowing these transistors to function at frequencies in excess of 250 GHz.

#5712.  Name the chemical element  atomic number 77. A very hard, brittle, silvery-white transition metal of the platinum group, it is generally credited with being the second densest element (after osmium) based on measured density, although calculations involving the space lattices of the elements show that it is denser. It is also the most corrosion-resistant metal, even at temperatures as high as 2000 °C. It is the most corrosion-resistant metal known: it is not attacked by almost any acid, aqua regia, molten metals, or silicates at high temperatures.

It is the world's second largest freshwater lake by surface area; only Lake Superior in North America is larger. In terms of its volume, it is the world's ninth largest continental lake, and it contains about 2,750 cubic kilometers (2.2 billion acre-feet) of water.

#5714.  Name an African Great Lake. It is estimated to be the second largest freshwater lake in the world by volume, and the second deepest, in both cases, after only Lake Baikal in Siberia; it is also the world's longest freshwater lake. The lake is divided among four countries – Tanzania, Democratic Republic of the Congo, Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. The water flows into the Congo River system and ultimately into the Atlantic Ocean.  is situated within the Albertine Rift, the western branch of the East African Rift, and is confined by the mountainous walls of the valley. It is the largest rift lake in Africa and the second largest lake by volume in the world. It is the deepest lake in Africa and holds the greatest volume of fresh water, accounting for 18% of the world's available fresh water.
