Question 1

In the original 'Ghostbusters' (1984), what was the name of the New York City library ghost — the first supernatural entity the team encountered — whose terrifying scream sent the trio fleeing down the steps?

Accepted Answer

Eleanor Twitty. Eleanor Twitty, known as 'the Grey Lady' or 'the Library Ghost,' was a quiet apparition surrounded by floating books who turned monstrous when disturbed. While 'Grey Lady' is a common real-world folklore trope, her specific character and backstory were created entirely for the Ghostbusters franchise rather than being based on an actual New York Public Library urban legend.

Question 2

The word 'assassin' traces back to an Arabic word — what does it literally mean, according to the most widely cited medieval origin story?

Accepted Answer

Hashish user. The word derives from 'hashshashin,' meaning hashish user, a term applied to the Nizari Ismaili order of medieval Syria and Persia whose members supposedly consumed the drug before missions. Modern historians debate whether this was a slur invented by their enemies rather than an actual practice.

Question 3

Which space mission, launched in 1989, was the first to map the entire surface of Venus using radar — revealing a young, volcanically active world resurfaced within the last 300–600 million years?

Accepted Answer

Magellan. NASA's Magellan spacecraft mapped 98% of Venus's surface with synthetic aperture radar before being deliberately plunged into the atmosphere in 1994. Its data revealed thousands of volcanoes alongside a sparse, pristine population of just over 900 impact craters, proving Venus was geologically resurfaced all at once in its recent past.

Question 4

Which insect communicates the direction and distance of a food source to its colony using a figure-eight dance — a discovery that won its researcher the Nobel Prize in Physiology in 1973?

Accepted Answer

Honeybee. Karl von Frisch decoded the honeybee's 'waggle dance' after decades of observation, showing that the angle of the dance encodes direction relative to the sun and the duration of the waggle run encodes distance. It remains one of the most sophisticated known animal communication systems.

Question 5

Which gemstone gets its deep blue color from trace amounts of iron and titanium — and was famously believed in medieval Europe to protect its wearer from envy and attract divine favor?

Accepted Answer

Sapphire. Sapphires are corundum crystals colored by iron and titanium impurities; rubies are the same mineral but colored by chromium. Medieval clergy favored sapphires in rings because they symbolized the heavens, and the British Crown Jewels feature several historically significant sapphires.
