General Knowledge Quiz: Saturday 30th January 2021

#1. Who wrote the novel Jaws, later turned into a blockbuster movie by Steven Spielberg?

Jaws is a 1974 novel by American writer Peter Benchley. It tells the story of a great white shark that preys upon a small resort town and the voyage of three men trying to kill it. The novel grew out of Benchley’s interest in shark attacks after he learned about the exploits of Montauk, New York shark fisherman Frank Mundus in 1964. Doubleday commissioned him to write the novel in 1971, a period when Benchley worked as a freelance journalist.

#2. Rubies are a red variety of corundum. What name is given to corundum gemstones of any other colour?

Corundum is a crystalline form of aluminium oxide typically containing traces of iron, titanium, vanadium and chromium. It is a rock-forming mineral. It is also a naturally transparent material, but can have different colors depending on the presence of transition metal impurities in its crystalline structure. Corundum has two primary gem varieties: ruby and sapphire. Rubies are red due to the presence of chromium, and sapphires exhibit a range of colors depending on what transition metal is present. A rare type of sapphire, padparadscha sapphire, is pink-orange.

#3. What is the only planet in our solar system which rotates clockwise around the sun?

Current theory holds that Venus initially spun in the same direction as most other planets and, in a way, still does: it simply flipped its axis 180 degrees at some point. In other words, it spins in the same direction it always has, just upside down, so that looking at it from other planets makes the spin seem backward. Scientists have argued that the sun’s gravitational pull on the planet’s very dense atmosphere could have caused strong atmospheric tides. Such tides, combined with friction between Venus’s mantle and core, could have caused the flip in the first place.

#4. Which branch of mathematics, using letters to represent numbers, comes from the Arabic 'reunion of broken parts'?

Algebra (from Arabic: الجبر‎ al-jabr, meaning “reunion of broken parts” and “bonesetting”) is one of the broad parts of mathematics, together with number theory, geometry and analysis. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics.It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields.

#5. What do you call substances that will not let thermal heat pass through them?

Metals are good conductors of thermal energy. Substances that do not allow thermal energy to move through them easily are called insulators. Air and plastics are insulators.

#6. What ocean was Amelia Earhart flying over when she disappeared?

During an attempt at becoming the first female to complete a circumnavigational flight of the globe in 1937 in a Purdue-funded Lockheed Model 10-E Electra, Earhart and navigator Fred Noonan disappeared over the central Pacific Ocean near Howland Island.

#7. What common flavouring is an extract of fermented and dried orchid pods?

Vanilla is a spice derived from orchids of the genus Vanilla, primarily obtained from pods of the Mexican species, flat-leaved vanilla (V. planifolia). The word vanilla, derived from vainilla, the diminutive of the Spanish word vaina (vaina itself meaning a sheath or a pod), is translated simply as “little pod”.

#8. Blur Crow, Brimstone, Owl and Ringlet are all types of what creature?

Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily “Hesperioidea”), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily “Hedyloidea”). Butterfly fossils date to the Paleocene, about 56 million years ago.

#9. Because metal was scarce, the oscars given out during WWII were made out of what?

The statuettes are solid bronze and plated in 24-karat gold. Due to a metal shortage during World War II, Oscars were made of painted plaster for three years. Following the war, the Academy invited recipients to redeem the plaster figures for gold-plated metal ones.

#10. What is a triangle whose sides are all of different lengths?

A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene.
