Ten questions, ten answers, all visible on the page. No quiz that hides the solution behind a button: here you read the answer right below, with a short explanation so you remember the “why”.
The questions span five fields — geography, history, art, science, nature — and rise steadily in difficulty. Four easy, four medium, two traps. To play solo, cover the line below with your hand. For a quiz night, read each question out loud and keep score.
Geography
1. What is the longest river in the world? (easy) Answer: the Nile, at roughly 6,650 km. It’s the classic dinner-table trap: some researchers credit the Amazon, whose length climbs past 6,900 km depending on where you place its source. In general knowledge, the Nile stays the expected answer.
2. What is the capital of Australia? (medium) Answer: Canberra, not Sydney or Melbourne. The two big cities fought over the title in the early 20th century. Rather than pick one, a brand-new capital was built between them. You’ll find the same logic on other continents in our capitals quiz by continent.
History
3. In what year did the Berlin Wall fall? (easy) Answer: 1989, on the night of 9 November. The fall of the Wall opened the way to German reunification and came to symbolise the end of the Cold War.
4. Who was the first Roman emperor? (hard) Answer: Augustus, born Octavian, from 27 BC. Many answer Julius Caesar, but Caesar never held the title of emperor: it was his adopted son who founded the Empire. To stop mixing up figures like these, see our roundup of major historical figures.
Already stuck? That’s actually a good sign. You remember an answer better once you’ve searched for it before reading it — which is exactly how a quiz app works: get it wrong, understand why, remember.
Art
5. Who painted the Mona Lisa? (easy) Answer: Leonardo da Vinci, between about 1503 and 1519. The painting hangs in the Louvre, behind glass, and remains the most visited artwork in the world.
6. Which museum holds the Venus de Milo? (medium) Answer: the Louvre, in Paris. This Greek statue was unearthed in 1820 on the island of Milos, without its arms. No one knows for certain what pose they formed. More on the Venus de Milo, and other must-knows in our essential artworks to know.
Science
7. Which metal is liquid at room temperature? (medium) Answer: mercury (symbol Hg). It’s the only metal that flows at 20 °C, which long earned it a place in thermometers before it was phased out for its toxicity.
8. Which is the hottest planet in the Solar System? (hard) Answer: Venus, at around 465 °C on its surface. The reflex is to say Mercury, closer to the Sun. But Venus’s thick atmosphere traps heat through the greenhouse effect, making it hotter still.
Nature
9. What is the largest animal alive on Earth? (easy) Answer: the blue whale, up to 30 metres long and nearly 150 tonnes. It’s also the largest animal that has ever lived, dinosaurs included.
10. How many hearts does an octopus have? (medium) Answer: three. Two pump blood to the gills, the third to the rest of the body. And its blood is blue, thanks to a copper-based pigment. Plenty more surprises in our strange and little-known animals.
Your score
Count one point per correct answer.
0 to 3 right: some foundations to firm up, no shame in it. The general knowledge guide lays out the fields to cover first.
4 to 7: solid general level. There’s still room on the trick questions, the ones that make the difference in exams and TV quizzes.
8 to 10: very strong. Move up a tier with our quiz by level, from easy to expert.
Want to go further
Ten questions is a warm-up. To go further, move on to our 20 or 50 general knowledge questions. And to really improve, what counts is consistency: a few minutes a day beat one long session a month.
That’s the idea behind SAPIRO. The app gathers hundreds of quizzes on geography (197 countries), history, art and nature, with an explanation behind every answer. Free, no ads. Perfect for a commute, a coffee break or a quiz night with friends. For a ready-made training plan, follow our method to revise general knowledge in 30 days.
Frequently asked questions
What are the most common general knowledge questions?
The classics revolve around capitals (Australia, Brazil, Kazakhstan), key dates (1789, 1945, 1989), geographic records (longest river, highest peak) and famous artworks like the Mona Lisa. They’re safe bets in quizzes and interviews alike.
How can I improve my general knowledge quickly?
Fifteen minutes a day is enough if it’s regular. Mix the formats — quizzes, podcasts, long reads — and look up the answer right away when a word or name escapes you. Active testing, like a quiz, sticks far better than simply re-reading.
What is the hardest general knowledge question?
Difficulty is personal: it all depends on your gaps. The questions that trip up the most people tend to be lesser-known capitals, the first emperors, or counter-intuitive scientific records like the hottest planet.
Where can I find free general knowledge quizzes?
The SAPIRO app offers hundreds of general knowledge questions, sorted by theme and level, free and ad-free. Every answer comes with an explanation, so you learn as you play.
