43 General Knowledge Questions [With Answers]

The capital of Australia is not Sydney. Octopuses have three hearts. The Great Wall is not visible from space.

Those three are warmups. The 43 general knowledge questions below run across seven categories, from science and history to food and mythology, each with an answer and a short breakdown of why it catches people. For this August 2026 update I re-verified all 43 answers, and two of them did not survive the check: the ant-biomass claim in question 7 and the Moon golf distance in question 32 are both corrected below, with sources.

One pattern is worth naming up front. In our own production answer data, the worst miss rates land not on obscure facts but on questions with a built-in decoy, where the famous answer arrives faster than the correct one: Russia over France, France over Belgium. That pattern runs all through this list. For single-subject sets instead, the trivia questions by topic page covers 22 categories.

What Are General Knowledge Questions?

General knowledge questions are quiz questions that test breadth across many unrelated subjects rather than depth in one. A round might jump from astronomy to the Hundred Years’ War to the origin of the word “salary,” so no single specialty carries you for long. Quiz hosts also call them knowledge questions or general information questions; the idea is the same either way: broad facts a curious adult could plausibly know, none requiring expert training.

Examples of knowledge questions in this style: Which country has the most time zones? What fruit is technically a berry? What was Nintendo’s original business before video games? All three are below, with answers and the reason each one fools people.

This list holds 43 of them across seven categories and three difficulty tiers: 11 easy, 18 medium, 14 hard. Easy questions exist for scoring rhythm; the medium and hard ones are what the room still argues about on the way home.

Category	Questions	Easy	Medium	Hard
Science & Nature	1-7	2	3	2
History	8-13	1	3	2
Geography & World	14-19	2	2	2
Pop Culture & Entertainment	20-25	2	2	2
Food & Drink	26-31	2	2	2
Sports	32-37	1	3	2
Language, Mythology & Philosophy	38-43	1	3	2
Total	43	11	18	14

43 general knowledge questions across seven categories, weighted toward medium and hard for maximum stump potential.

Science & Nature Questions (1-7)

Seven questions from biology, ecology, astronomy, and biochemistry. This is where confident guesses have the shortest life expectancy, starting with a tree census that embarrassed a lot of stargazers.

Science & Nature: 7 questions that make you rethink what you thought you knew.

1. Which has more: trees on Earth or stars in the Milky Way? (Easy)

Answer: Trees. Earth has roughly 3 trillion trees against an estimated 200 to 400 billion stars in the Milky Way.

Why it stumps people: Space feels infinite. Trees feel countable. Yet even the high-end star estimate leaves at least seven trees for every star in the galaxy. A 2015 study published in Nature used satellite imagery and ground surveys to arrive at the 3 trillion figure, eight times higher than previous estimates.

2. What percentage of the ocean floor has been mapped in high resolution? (Easy)

Answer: About a quarter. The Seabed 2030 mapping project put the figure at 26 percent in 2024.

Where it goes wrong: We have mapped 100 percent of the Moon’s surface, and nearly all of Mars. Our own ocean floor lags because sonar is slow and costly next to orbital imaging, and the deep ocean is enormous.

3. Which came first: sharks or trees? (Medium)

Answer: Sharks, by roughly 50 million years. Sharks appeared about 450 million years ago. The first trees evolved around 400 million years ago.

The trap: your gut says trees, because they feel ancient and fundamental. The first sharks swam Earth’s oceans when land was mostly barren rock and moss, and sharks predate dinosaurs by over 200 million years, surviving all five mass extinction events along the way. If you want more science surprises, our 37 science trivia questions go deeper into physics, biology, chemistry, and space. For a format that weaponizes common misconceptions directly, try our 53 true or false questions.

4. What planet rains diamonds? (Medium)

Answer: Neptune (and Uranus). Extreme pressure and heat deep in these planets’ atmospheres compress carbon atoms into diamond crystals that fall like rain.

Why it stumps people: This reads like science fiction until you check the physics behind it. Researchers at SLAC National Accelerator Laboratory replicated the conditions and produced actual nanodiamonds in the lab. The diamonds on Neptune are thought to eventually sink to the core, forming a thick diamond layer. For more planetary surprises, see our 42 space trivia questions. For the full six-round UK format, jump to 97 pub quiz questions.

Now for one that trips up biology students specifically.

5. What is the most abundant protein on Earth? (Medium)

Answer: RuBisCO, the enzyme in plant leaves that drives photosynthesis.

The reflex answers are collagen (the biology student’s favorite), keratin, or gluten. All wrong. Plants produce RuBisCO in staggering quantities because it is the enzyme that converts CO2 into sugar, and an estimated 700 million tons exist on Earth at any given time, the most common protein by a wide margin.

6. What percentage of all species that ever lived are now extinct? (Hard)

Answer: Over 99%.

The blind spot: we think of extinction as rare and catastrophic, five events, each one a headline. In reality extinction is the background hum of evolution, and the vast majority of life that ever existed left no descendants. Every species alive today, including us, belongs to the surviving fraction of a fraction.

7. How does the total biomass of all ants on Earth compare to that of all humans? (Hard)

Answer: About one fifth of human biomass. The classic pub-quiz claim that ants and humans weigh roughly the same is wrong.

Full disclosure: an earlier version of this page gave the classic answer, “roughly comparable,” and cited a 2022 study in the Proceedings of the National Academy of Sciences as support. While re-checking every answer for this update I actually read the study, and it refutes the factoid it was supposed to support: Earth’s roughly 20 quadrillion ants add up to about 12 million tonnes of dry carbon, around 20 percent of human biomass measured the same way. The parity claim was popularized in the 1990s and did not survive the first rigorous census. The ants keep one title, though: they still outweigh all wild birds and wild mammals combined.

History Questions (8-13)

Six history questions, and not a date-memorization drill among them. The timelines here are for rearranging, not reciting. The full 43-question history set lives in our 43 history trivia questions.

History: 6 questions that rearrange your mental timeline.

8. How long did the Hundred Years’ War actually last? (Easy)

Answer: 116 years, from 1337 to 1453.

The catch: the name is a convenient label historians applied later. The conflict between England and France included long truces, regime changes, and flare-ups across more than a century, so the century label was always approximate. And Joan of Arc didn’t appear until year 92.

9. What was Cleopatra closer in time to: the building of the Great Pyramids or the Moon landing? (Medium)

Answer: The Moon landing. The Great Pyramids were built around 2560 BCE. Cleopatra lived around 30 BCE. The Moon landing was 1969 CE. That puts her roughly 2,530 years after the pyramids and only 1,999 years before the Moon landing.

The mental block: ancient Egypt ran for over 3,000 years, longer than the entire Common Era so far, and compressing that into a single era hides how late Cleopatra arrived in it. She reigned at the very end, nearer to us than to the pyramid builders.

10. Which country was the first to grant women the right to vote in national elections? (Medium)

Answer: New Zealand, in 1893.

Where the guesses go: nearly everyone reaches for a Scandinavian or European country. New Zealand was decades ahead of the United States (1920), the United Kingdom (1928), and France (1944). Kate Sheppard drove the campaign, and her petition carried the signatures of nearly one in four adult European women in the country.

11. How long did the shortest war in recorded history last? (Medium)

Answer: Between 38 and 45 minutes. The Anglo-Zanzibar War on August 27, 1896.

Why it stumps people: It barely qualifies as a battle. The British issued an ultimatum to the new Sultan of Zanzibar. He refused. The Royal Navy bombarded the palace, the sultan fled through a back door, and it was over before the morning was out.

12. What common household product was originally sold as a surgical antiseptic? (Hard)

Answer: Listerine mouthwash. Invented in 1879 as a surgical antiseptic, it was later marketed for floors, dandruff, and finally halitosis in the 1920s.

The twist: Listerine invented “bad breath” as a social crisis. The term halitosis existed in medical literature but was almost unknown to the public until Listerine’s ad campaigns turned it into a household fear. Sales increased 8,000% between 1922 and 1929.

13. Which ancient civilization had indoor plumbing first? (Hard)

Answer: The Indus Valley civilization (Mohenjo-daro and Harappa), around 2500 BCE. They had flush toilets, covered drains, and a city-wide sewage system.

Where the credit goes wrong: Greece and Rome own the reputation for ancient engineering. But the Indus Valley had sophisticated urban water management a full thousand years before Roman aqueducts, and nearly every house in Mohenjo-daro had a private bathroom connected to a municipal drainage network.

Geography & World Questions (14-19)

Your mental map is tidier than the planet. These six run from time zones to the letters of the alphabet, and the tidy version loses every time. The full set is in our 43 geography trivia questions that stump everyone.

Geography & World: 6 questions that redraw your mental map.

14. Which country has the most time zones? (Easy)

Answer: France, with 12 time zones (including overseas territories like French Polynesia, New Caledonia, Martinique, and Reunion).

Why it stumps people: Russia, with its 11 zones, is the answer everyone fires off first, and it’s wrong. France’s scattered overseas territories span the globe from the Caribbean to the South Pacific, giving it one more time zone than the largest country on Earth.

15. What is the driest place on Earth? (Easy)

Answer: The McMurdo Dry Valleys in Antarctica. Some areas haven’t seen rain or snow in roughly 2 million years.

The reflex: picture “driest place” and the Sahara or the Atacama comes to mind first. Yet Antarctica is technically a desert too (under 250 mm of precipitation per year across the continent), and the Dry Valleys are the extreme within the extreme: wind-scoured rock with nearly zero moisture.

16. In which direction does the Panama Canal run from the Atlantic to the Pacific? (Medium)

Answer: Southeast. The Pacific entrance is actually east of the Atlantic entrance.

The compass fails everyone here. Panama’s S-shaped curve bends so hard that a ship leaving the Atlantic side travels southeast to reach the Pacific, so “Atlantic east, Pacific west” falls apart here. You can watch the sun rise over the Pacific end of the canal.

17. What country has more pyramids than Egypt? (Medium)

Answer: Sudan. It has over 200 pyramids (the Nubian pyramids of Meroe and other sites) compared to Egypt’s roughly 130.

Where it goes wrong: Egypt defined the word “pyramid” in popular imagination. The Kingdom of Kush, centered in what is now Sudan, built smaller and steeper pyramids in far greater numbers over several centuries, and they receive a tiny fraction of the tourist attention.

18. What is the least densely populated country on Earth? (Hard)

Answer: Mongolia, with roughly 2 people per square kilometer.

Why Greenland doesn’t count: it would win easily, but it is a territory of Denmark, not an independent country. Mongolia’s vast steppe is home to more horses than people in some provinces. The capital, Ulaanbaatar, holds nearly half the country’s entire population.

19. What is the only letter of the alphabet that doesn’t appear in any US state name? (Hard)

Answer: Q.

The wrong letters: X and Z jump out first, but Texas covers X and Arizona covers Z. Every other letter appears at least once across the 50 states. Q never does.

Pop Culture & Entertainment Questions (20-25)

Pop culture is the one category where the room’s age decides the miss: a 20-year-old and a 50-year-old will get the same question wrong in two different directions. These six cover film, music, gaming, and television. For film-only rounds, our 43 movie trivia questions go deeper.

Pop Culture & Entertainment: 6 questions that cross generations.

20. What was Nintendo’s original business before video games? (Easy)

Answer: Playing cards. Nintendo was founded in 1889 in Kyoto, Japan, making handmade hanafuda (flower cards).

The company behind Mario, Zelda, and the Switch spent its first 80 years far from screens. Before finding video games in the 1970s, Nintendo also experimented with taxi services, instant rice, and short-stay hotels.

21. What is the highest-grossing film of all time (not adjusted for inflation)? (Easy)

Answer: Avatar (2009), with about $2.9 billion in worldwide box office.

The reflex answer is Avengers: Endgame, because Marvel dominates the conversation. Endgame came close at $2.8 billion but fell short, and Avatar reclaimed the top spot after a 2022 re-release. Adjusted for inflation, Gone with the Wind (1939) still leads. For franchise-specific film trivia, our 37 Harry Potter trivia questions push even devoted Potterheads past what the movies show.

22. Which band has sold the most records worldwide? (Medium)

Answer: The Beatles, with estimated sales exceeding 600 million units.

Two names trip people up: Elvis Presley and Michael Jackson. Both are close competitors with massive sales numbers, and both fall short. The Beatles’ combined album and singles sales outpace every other act in recording history, and their catalog continues to sell decades after the breakup.

23. What is the best-selling video game of all time? (Medium)

Answer: Minecraft, with over 300 million copies sold across all platforms.

Why it stumps people: Tetris held this record for decades. Minecraft overtook it and continues to sell. For perspective, 300 million copies means roughly 1 in 25 people on Earth has purchased the game. Grand Theft Auto V (over 200 million) is a distant second.

24. What was the first toy advertised on television? (Hard)

Answer: Mr. Potato Head, in 1952.

Before 1952, toys were pitched to parents, not children. Print catalogs were the channel, and the buyer was an adult. Mr. Potato Head broke that wall by advertising straight to kids through the screen, and sales hit over $4 million in the first year.

25. What is the longest-running animated TV show in American history? (Hard)

Answer: The Simpsons, on the air since December 17, 1989 (35+ seasons and counting).

Why it stumps people: South Park and Family Guy are also long-running, but neither approaches The Simpsons’ tenure. The show has been on air longer than many of its current viewers have been alive. It overtook Gunsmoke as the longest-running American primetime scripted series in 2018.

Food & Drink Questions (26-31)

Everyone has food opinions. Food facts are rarer, which is why this category starts more table arguments than any other. Six questions on origins, biology, and consumption, with 43 more in the complete food trivia guide.

Food & Drink: 6 questions where confidence gets you burned.

26. Where were French fries invented? (Easy)

Answer: Belgium, not France. Belgian villagers along the Meuse River were frying thin cuts of potato by the late 1600s.

The name says French. The potatoes say otherwise. American soldiers stationed in French-speaking Belgium during World War I encountered the dish, assumed they were in France, and brought the misnomer back home.

27. What is the most consumed beverage in the world after water? (Easy)

Answer: Tea.

The go-to guess is coffee, because coffee runs Western media and social feeds. The world drinks more tea. China, India, Turkey, Japan, and the United Kingdom collectively down enough of it to leave coffee in a distant second place.

28. What fruit is technically a berry: a strawberry, a banana, or a raspberry? (Medium)

Answer: A banana. Botanically, a berry develops from a single ovary and contains seeds within the flesh. Bananas qualify. Strawberries and raspberries do not.

The mix-up: botanical definitions ignore everyday language completely. Grapes, tomatoes, eggplants, and avocados are also true berries, while strawberries are accessory fruits and raspberries are aggregate drupes. The words mean something very different in a botany lab than in a grocery store.

29. What is the most stolen food in the world? (Medium)

Answer: Cheese. An estimated 4% of all cheese produced globally is stolen each year.

Why it stumps people: The number sounds made up. It’s from a 2011 report by the UK’s Centre for Retail Research. Cheese is expensive, easy to conceal, hard to trace, and in high demand for resale; the black market for premium cheese is a documented problem, particularly in Europe, with Parmigiano-Reggiano and aged Gouda as favorite targets.

30. Which country drinks the most coffee per capita? (Hard)

Answer: Finland, at roughly 12 kilograms per person per year.

Where the guesses go: Italy, Brazil, or Colombia. Finland’s consumption is nearly double Italy’s. Long, dark winters and a deep cultural tradition of kahvitauko (coffee break, sometimes taken three or four times daily) drive the numbers. Norway and Iceland rank second and third.

31. What is the most expensive spice in the world by weight? (Hard)

Answer: Saffron. It takes roughly 75,000 crocus flowers to produce a single pound, and most of the harvesting is done by hand.

Vanilla gets the headlines during price spikes, but saffron consistently costs $5,000 to $10,000+ per kilogram. Each crocus flower produces only three tiny stigma threads. The harvest window is a few weeks per year, and the threads must be picked at dawn before the flowers open fully.

Sports Questions (32-37)

Sports trivia keeps wandering off the scoreboard: golf on the Moon, a marathon distance set by royal seating preferences, a playing field the size of nine football fields. These six reward whoever reads past the box score, and so do our 43 sports trivia questions if you want a deeper bench.

Sports: 6 questions that go beyond scoreboards.

32. What sport was the first played on the Moon? (Easy)

Answer: Golf. Alan Shepard hit two golf balls during the Apollo 14 mission in February 1971.

The correction: the Moon and athletics don’t overlap in anyone’s mental model, so the story invites exaggeration. Shepard smuggled a makeshift 6-iron head onto the mission, attached it to a sample-collection tool, and swung one-handed in a pressurized suit. He claimed the second ball went “miles and miles,” and until this update the page repeated a 200-yard estimate. Both were wrong: in a 2021 analysis published by the USGA, imaging specialist Andy Saunders digitally enhanced the Apollo 14 photographs, located both balls, and measured the second shot at about 40 yards.

33. What does “BMX” in BMX racing stand for? (Medium)

Answer: Bicycle motocross.

Riders compete in BMX for years without wondering about the name. The sport started in the early 1970s when kids in Southern California began racing bicycles on dirt tracks, copying motocross motorcycle riders. The abbreviation stuck, the sport professionalized, and by 2008 it was an Olympic event.

34. How long is a marathon, and why that exact distance? (Medium)

Answer: 26.2 miles (42.195 km), the length of the 1908 London Olympics course, laid out so the race could start at Windsor Castle and finish in front of the royal box at the Olympic stadium.

Why it stumps people: Everyone assumes the distance traces back to Pheidippides running from Marathon to Athens in 490 BCE. That legend inspired the event, but the actual distance shifted with every early Olympics until the 1908 London course length was adopted as the official standard in 1921. A royal family’s seating preference became the most-run distance in the world.

35. Which sport uses the largest playing field? (Medium)

Answer: Polo. A full-size polo field is 300 yards long by 160 yards wide (about 10 acres), roughly nine times the playing area of an American football field.

The trap here is familiarity. Cricket, golf, and horse racing all seem plausible because we’ve seen them on TV. But polo fields have to be enormous: horses gallop at 35+ mph, players swing mallets at full speed, and the ball travels hundreds of yards per hit, with fast direction changes eating up a staggering amount of open ground.

36. What Olympic sport awards the most gold medals in a single Games? (Hard)

Answer: Athletics (track and field). At the 2024 Paris Olympics, athletics offered 48 gold-medal events, more than any other sport.

Swimming gets the primetime spotlight with 35 events at Paris 2024, while athletics quietly awards 48 golds across sprints, distance races, jumps, throws, walks, decathlon, and heptathlon.

37. What country invented basketball? (Hard)

Answer: The United States, but the inventor was Canadian. James Naismith, born in Almonte, Ontario, created basketball in 1891 while teaching at a YMCA training school in Springfield, Massachusetts.

Why it stumps people: This catches even die-hard fans. Basketball is synonymous with American culture, but its inventor was Canadian. Naismith needed an indoor game to keep his students active during harsh New England winters, so he nailed a peach basket to a 10-foot elevated track and wrote 13 rules. Within a decade, the sport had spread globally.

Language, Mythology & Philosophy Questions (38-43)

The last six come from the margins: word origins, dead gods, and one very translated document. They tend to change how you read the other 37. Greek myth gets a deeper cut in LearnClash’s Greek mythology topic.

Language, Mythology & Philosophy: 6 questions that change how you read everything else.

38. What does “OK” originally stand for? (Easy)

Answer: “Oll Korrect,” a humorous misspelling of “all correct.” It first appeared in a Boston newspaper on March 23, 1839.

Why it stumps people: “OK” is one of the most recognized words on the planet, used in almost every language. Its origin is weirdly mundane: an 1839 newspaper joke during a trend of playful abbreviations (KY for “know yuse,” KG for “know go”). Most of the abbreviations died. OK never stopped.

39. What language has the most native speakers worldwide? (Medium)

Answer: Mandarin Chinese, with about 920 million native speakers.

English runs the internet, global business, and the entertainment industry, so most people assume it leads in native speakers too. English has roughly 380 million native speakers, less than half of Mandarin’s total. It wins as a second language, not by birth.

40. In Norse mythology, what happens at Ragnarok? (Medium)

Answer: The end of the world. Gods including Odin and Thor die in a final battle against giants and cosmic monsters. The world is consumed by fire and water, then reborn.

Marvel framed it as one battle. The films flattened it, but the myth is bigger. The actual myth is a complete cosmological cycle: destruction followed by renewal, with a green, peaceful, empty world emerging and two surviving humans, Lif and Lifthrasir, repopulating it. The story is about rebirth, not just destruction. Tolkien drew heavily from Norse mythology when building Middle-earth, and our 37 Lord of the Rings trivia questions test whether you know the world he constructed from these roots.

41. What is the most translated document in the world? (Medium)

Answer: The Universal Declaration of Human Rights, available in over 500 languages and dialects.

The Bible is the reflexive answer, and it is translated into more languages overall. But the UDHR holds the Guinness World Record for the most translations of a single, continuous document; it was deliberately translated into as many languages as possible to emphasize its universal applicability. Speaking of the Bible, our bible trivia questions collection covers 67 questions across Old Testament, New Testament, and the misconceptions almost everyone repeats.

42. What is the origin of the word “salary”? (Hard)

Answer: The Latin word salarium, connected to salt. Roman soldiers may have received an allowance to purchase salt, or were compensated partly in salt.

Why it stumps people: Historians still argue over the exact link. What nobody argues is that salt mattered: before refrigeration it preserved food, which made it a valuable trade good, and the phrase “worth your salt” comes from the same root. Whether soldiers got actual salt crystals or money set aside for salt, that part stays open.

43. What is the oldest known written story in the world? (Hard)

Answer: The Epic of Gilgamesh, written on clay tablets in ancient Sumer (modern Iraq) around 2100 BCE.

Why it stumps people: Homer already feels like the beginning of literature, and the Iliad is from around 800 BCE. By then Gilgamesh had been on clay for some 1,300 years: a king hunting immortality after losing his closest friend, complete with a flood account that is centuries older than the story of Noah and strikingly similar to it.

Keeping the Ones You Missed

Run the 43 once and note your misses. Then come back to exactly those in a few days. Pulling an answer out of your own head does more for retention than rereading it ever will, which is the well-replicated testing effect, and it works best on the questions that stung:

“Practicing retrieval produces greater gains in meaningful learning than elaborative studying with concept mapping.” Karpicke & Blunt, Science (2011)

General knowledge is the hardest category to fake precisely because the facts refuse to cluster. A banana, a 38-minute war, and Mongolia’s empty steppe will never share a mental shelf, so each one has to be fetched cold, the way it shows up at trivia night. That breadth problem is also why a standard LearnClash duel deals 18 questions across six topics, three per topic: when we tested formats during development, six topics per duel turned out to be the number that kept one-trick specialists from dominating. Ranked matches run on an ELO-style rating, and every miss feeds a spaced repetition queue with exactly two checkpoints. Get one wrong and it resurfaces after 7 days; get one right and the next look is 90 days out; two correct answers in a row retire it for good; miss again and it drops one stage, not back to zero. See how that setup compares with Kahoot or Trivia Crack.

Hosting a quiz night instead? Deal one category per round and score hard questions double, so the mythology specialists and the sports fans each get their inning. We also published a free open-source trivia database with 100 questions across 8 categories, downloadable as JSON and licensed under CC BY 4.0. And when the general round runs dry, our 53 TV trivia questions cover everything from M*A*S*H records to the real sounds behind Law & Order’s famous “chung-chung.”
