Case File #0066

Aug 26, 2026 — 10 rounds, declassified. The fabrication in each is marked; the truth of all three follows. Play today's case →

  1. Round 1 FOOD
    • ✓ TRUE

      Carrots were originally cultivated in colors like purple and yellow, with orange becoming common only later.

      TRUE. Early domesticated carrots were purple and yellow; the familiar orange carrot rose to prominence centuries afterward.

    • ✗ FABRICATION

      Wild carrots were first domesticated for their sweet roots in ancient Egypt around the same time as wheat.

      FALSE. Carrot domestication is centered on Central Asia far more recently, and early carrots were grown for leaves and seeds, not sweet roots.

    • ✓ TRUE

      Early carrot growing valued the plant's aromatic leaves and seeds before its root became the prize.

      TRUE. Like related plants, the carrot was first useful for its foliage and seeds before selective breeding fattened the root.

  2. Round 2 GEOGRAPHY
    • ✗ FABRICATION

      Australia's capital is Sydney, its most populous city and the home of the famous harbourside Opera House.

      FALSE. Australia's capital is Canberra. Sydney is the biggest city, but it has never been the capital.

    • ✓ TRUE

      Canberra was purpose-built as Australia's capital, a compromise to settle the rivalry between Sydney and Melbourne.

      TRUE. Neither big city would yield, so a brand-new capital was planned between them.

    • ✓ TRUE

      Sydney is Australia's most populous city, with a population well above four million people.

      TRUE. Sydney is Australia's largest city by population, even though it isn't the capital.

  3. Round 3 FOOD
    • ✓ TRUE

      Early forms of sushi used fermented rice to preserve fish, and that rice was often thrown away rather than eaten.

      TRUE. In early 'narezushi,' rice fermentation preserved the fish and the rice was frequently discarded before eating.

    • ✗ FABRICATION

      The fast, hand-pressed vinegared-rice 'nigiri' style was invented in Kyoto's imperial court in the 1600s.

      FALSE. Nigiri arose in Edo (old Tokyo) in the early 1800s as fast street food, not in Kyoto's court in the 1600s.

    • ✓ TRUE

      Adding vinegar to sushi rice both seasons it and echoes the sourness that fermentation once provided.

      TRUE. Vinegared rice mimics the tang of older fermented sushi while letting the dish be made quickly.

  4. Round 4 GEOGRAPHY
    • ✓ TRUE

      The Nile is one of the world's longest rivers and flows generally northward, emptying into the Mediterranean Sea.

      TRUE. Unusually, the Nile flows north and drains into the Mediterranean via its Egyptian delta.

    • ✓ TRUE

      The Amazon discharges more water into the ocean than any other river on Earth.

      TRUE. By sheer volume of water discharged, the Amazon dwarfs every other river.

    • ✗ FABRICATION

      The Nile lies entirely within Egypt, running from its source to its mouth without leaving the country.

      FALSE. The Nile crosses many countries; its waters gather from the Great Lakes region and Ethiopia before reaching Egypt.

  5. Round 5 NATURE
    • ✓ TRUE

      Glaciers hold most of the world's fresh water, far more than all the rivers and lakes combined.

      TRUE. Ice sheets and glaciers lock up the majority of Earth's fresh water.

    • ✓ TRUE

      Glaciers are slow rivers of ice that flow downhill under their own weight, carving and reshaping valleys as they move.

      TRUE. Despite looking solid, glacial ice deforms and creeps downhill over years.

    • ✗ FABRICATION

      A glacier is a solid, motionless sheet of ice that never moves or changes within a human lifetime.

      FALSE. Glaciers flow continuously, and many advance or retreat measurably within years.

  6. Round 6 SPACE
    • ✓ TRUE

      Jupiter's Great Red Spot is a colossal storm that has been observed raging for at least a couple of centuries.

      TRUE. This anticyclone is wide enough to swallow Earth and has persisted through generations of observation.

    • ✗ FABRICATION

      Jupiter has exactly four moons, all of them discovered by Galileo Galilei in 1610.

      FALSE. Galileo found the four largest moons, but Jupiter is now known to have dozens more, over ninety in total.

    • ✓ TRUE

      Jupiter is so massive that the balance point it shares with the Sun lies just outside the Sun's surface.

      TRUE. The Sun and Jupiter orbit a common center of mass that sits slightly above the Sun's visible edge.

  7. Round 7 HISTORY
    • ✗ FABRICATION

      Albert Einstein failed mathematics as a schoolboy and very nearly abandoned his studies before switching to physics.

      FALSE — Einstein excelled at mathematics from a young age; he himself dismissed the failing-math story as nonsense.

    • ✓ TRUE

      In 1905, his so-called miracle year, Einstein published four papers that reshaped modern physics.

      TRUE — the 1905 papers covered the photoelectric effect, Brownian motion, special relativity, and mass-energy equivalence.

    • ✓ TRUE

      Einstein was offered the presidency of the state of Israel in 1952 but politely turned it down.

      TRUE — he declined, saying he lacked the aptitude for dealing with people and official duties.

  8. Round 8 GEOGRAPHY
    • ✗ FABRICATION

      The capital of Switzerland is Zurich, its largest city and leading financial centre.

      FALSE. Switzerland's seat of government is Bern; Zurich is the largest city but not the capital.

    • ✓ TRUE

      Zurich is Switzerland's largest city and a major hub of global banking and finance.

      TRUE. Zurich is the biggest Swiss city and a world financial centre.

    • ✓ TRUE

      Bern serves as the seat of Switzerland's federal government.

      TRUE. Bern hosts the Swiss federal government, functioning as the capital.

  9. Round 9 LANGUAGE
    • ✗ FABRICATION

      The use of 'bug' for a computer fault began entirely with a real moth found jamming a machine in 1947, the first time the word ever meant a technical fault.

      FALSE. The 1947 moth was a fun real incident, but 'bug' for a technical defect was already in use decades earlier, so it was not the first such use.

    • ✓ TRUE

      The word 'spam', for unwanted bulk messages, is widely traced to a Monty Python sketch built around the canned meat of the same name.

      TRUE. The sketch's endless repetition of 'spam' inspired the term for flooding inboxes with repetitive junk.

    • ✓ TRUE

      The word 'byte' was spelled deliberately with a 'y' to keep it from being confused with the smaller unit 'bit' in writing.

      TRUE. The respelling avoided accidental clipping to 'bit' and gave the eight-bit unit a distinct look.

  10. Round 10 GEOGRAPHY
    • ✓ TRUE

      Greenland is the world's largest island that is not classified as a continent.

      TRUE. Greenland is the biggest island on Earth that isn't a continent.

    • ✓ TRUE

      Indonesia is an archipelago made up of many thousands of separate islands.

      TRUE. Indonesia consists of thousands of islands spread across the equator.

    • ✗ FABRICATION

      Australia is officially classified as the world's largest island rather than as a continent.

      FALSE. Australia is considered a continent, not an island; Greenland is the largest island.
