1. Q: How many officially recognised constellations are there in modern astronomy?
   A: 88. Together, the 88 constellations cover the entire celestial sphere, meaning every point in the sky belongs to one of them.
2. Q: How many eyeballs does a four-eyed fish have?
   A: Two eyes. A unique structure divides each eye into upper and lower halves. Furthermore, each half possesses its own pupil. Consequently, this unusual anatomy creates the illusion of four distinct eyes. Most importantly, it allows the creature to simultaneously see both above and below the water’s surface.
3. Q: How many “hearts” or aortic arches does an earthworm have?
   A: five pairs of hearts, totalling ten. These specialised structures are located near the mouth and operate together to circulate oxygenated blood, which the worm absorbs through its skin
4. Q: How many karats is pure unalloyed gold?
   A: 24 karats (24K). 24K gold contains 99.9% to 100% gold, establishing it as the highest standard of purity. However, this extreme purity also makes the metal very soft, malleable, and highly susceptible to scratches. Consequently, jewellers rarely craft everyday jewellery from it. Instead, investors and artisans prefer 24K gold for investment bars, coins, and high-value decorative pieces.
5. Q: In March 2025, NASA astronauts Butch Wilmore and Suni Williams finally returned to Earth after being “stranded” on the ISS. How long did their original 8-day mission last?
   A: 9 months/286 days. Launching on June 5, 2024, on Boeing’s Starliner, they remained on the International Space Station (ISS) until March 18, 2025, returning via a SpaceX Dragon capsule due to safety concerns with their original vessel.
6. Q: Leatherjackets are the larvae of which insect?
   A: Crane flies (family Tipulidae). Commonly known as “daddy long-legs”. These legless, greyish-brown, soil-dwelling grubs are well-known garden pests that feed on the roots and stems of grass and various plants, often causing significant damage to lawns.
7. Q: Lockjaw is another name for which disease?
   A: Tetanus. An early and common symptom is stiffening of the jaw muscles (trismus), making it difficult or impossible to open the mouth.
8. Q: Where on the human body is the area named “the glabella”?
   A: Between the eyebrows. This smooth, hairless area of skin is a highly expressive part of the face, and the underlying muscles are responsible for squinting and frowning.
9. Q: Which ocean-dwelling animal has the highest sense of smell?
   A: Sharks (particularly the Great White Shark) hold the title for the most powerful sense of smell. Often called “swimming noses,” they can detect certain chemicals, like blood, at concentrations as low as one part per 10 billion—the equivalent of a single drop in an Olympic-sized pool.
10. Q: How many naturally occurring magnetic elements are there at Room-Temperature?
    A: 3. Iron, Cobalt, Nickel. In their natural state, these metals lack intrinsic magnetism. However, objects producing magnetic fields readily attract them. Furthermore, once an external force magnetises them, they transform into actual magnets.
