1. Honey stored in ancient Egyptian tombs was found to be edible after thousands of years. This is because honey never what?
- A.Freezes
- B.Spoils✓ Correct
- C.Changes colour
- D.Crystallises
Answer: Spoils. Honey never spoils due to its low moisture content, acidic pH, and the presence of hydrogen peroxide. Archaeologists have found 3,000-year-old honey in Egyptian tombs that was still perfectly edible. As long as it is stored sealed, honey can last indefinitely.
2. How many hearts does an octopus have?
- A.1
- B.2
- C.3✓ Correct
- D.4
Answer: 3. Octopuses have 3 hearts: one main heart (the systemic heart) pumps blood around the body, while two branchial hearts pump blood through each of the two gills. They also have blue blood because it uses copper-based haemocyanin instead of iron-based haemoglobin.
3. Botanically speaking, are bananas technically berries?
- A.True✓ Correct
- B.False
- C.Only yellow ones
- D.Only plantain varieties
Answer: True. Botanically, bananas are classified as berries — a fruit that develops from a single flower with one ovary. By the same definition, strawberries, raspberries and blackberries are NOT true berries. Other true berries include avocados, tomatoes, and kiwis.
4. What is the collective noun for a group of flamingos?
- A.A flock
- B.A flamboyance✓ Correct
- C.A pride
- D.A colony
Answer: A flamboyance. A group of flamingos is called a 'flamboyance' — perfectly fitting their vibrant pink plumage. Flamingos get their pink colour from the carotenoid pigments in the algae and crustaceans they eat. Without this diet, they would actually be white.
5. Sharks are older than trees. True or false?
- A.True✓ Correct
- B.False
- C.About the same age
- D.Trees are older
Answer: True. This is true! Sharks have existed for approximately 450 million years, while the first trees appeared only about 385 million years ago. Sharks have survived five mass extinction events that wiped out the majority of life on Earth, making them one of evolution's great success stories.
6. How many eyes does a bee have?
- A.2
- B.3
- C.4
- D.5✓ Correct
Answer: 5. Bees have 5 eyes: 2 large compound eyes on the sides of their head (giving wide-angle vision) and 3 tiny simple eyes (ocelli) on top of the head that detect light intensity. The compound eyes can also see ultraviolet light, helping bees navigate by the sun.
7. Which animal cannot stick out its tongue?
- A.Elephant
- B.Crocodile✓ Correct
- C.Giraffe
- D.Hippo
Answer: Crocodile. Crocodiles cannot stick out their tongues — their tongues are attached to the roof of their mouths by a membrane and cannot move freely. Despite this, crocodiles do have taste buds and are surprisingly sensitive to salt, which is why saltwater crocodiles can live in the sea.
8. A snail can sleep for how long during periods of drought?
- A.1 week
- B.1 month
- C.6 months
- D.Up to 3 years✓ Correct
Answer: Up to 3 years. Snails can enter a state of dormancy called estivation for up to 3 years if conditions are too hot or dry. They seal their shell with a layer of mucus to prevent water loss. Their metabolism slows dramatically during this period, allowing them to survive without food or water.
9. Which fruit has its seeds on the outside?
- A.Pomegranate
- B.Strawberry✓ Correct
- C.Kiwi
- D.Raspberry
Answer: Strawberry. The strawberry is the only fruit that has its seeds on the outside. What looks like seeds are actually achenes — each one is a tiny fruit in itself containing a seed inside. A single strawberry has about 200 of these achenes on its surface.
10. Which civilisation is widely credited with inventing chocolate?
- A.Ancient Egyptians
- B.Ancient Romans
- C.Mesoamerican civilisations (Aztec/Maya)✓ Correct
- D.Ancient Chinese
Answer: Mesoamerican civilisations (Aztec/Maya). Cacao was first cultivated and used by ancient Mesoamerican civilisations — particularly the Olmec, Maya and Aztecs — as far back as 1900 BCE. They drank it as a bitter, spiced beverage. The Aztec Emperor Moctezuma reportedly consumed up to 50 cups of cocoa drink per day.
11. Which is the only mammal capable of true, sustained flight?
- A.Flying squirrel
- B.Bat✓ Correct
- C.Sugar glider
- D.Colugo
Answer: Bat. Bats are the only mammals capable of true flight. Other so-called 'flying' mammals, such as flying squirrels, only glide. Bats' wings are formed from skin stretched between their elongated finger bones.
12. A 'jiffy' is often used to mean 'a moment', but is it also a real, defined unit of time?
- A.Yes, it's a real unit✓ Correct
- B.No, it's just slang
- C.Only in cooking
- D.Only in sports
Answer: Yes, it's a real unit. A 'jiffy' really is a defined unit of time in physics and engineering, though its exact length varies by field — in electronics it can mean the period of one alternating-current cycle, and in physics it can refer to incredibly tiny fractions of a second.
13. Which animal has the largest eyes of any creature on Earth?
- A.Blue whale
- B.Giant squid✓ Correct
- C.Ostrich
- D.Elephant
Answer: Giant squid. The giant squid (and its relative the colossal squid) has the largest eyes of any animal, measuring up to about 27 cm across — roughly the size of a dinner plate. Such enormous eyes help it detect prey and predators in the deep, dark ocean.
14. What is the collective noun for a group of crows?
- A.A murder✓ Correct
- B.A pack
- C.A herd
- D.A swarm
Answer: A murder. A group of crows is famously called a 'murder'. English has many unusual collective nouns for birds, such as a 'parliament' of owls and an 'unkindness' of ravens.
15. Ironically, the fear of long words has a very long name. Roughly how long is it?
- A.Around 10 letters
- B.Around 20 letters
- C.Around 36 letters✓ Correct
- D.Around 5 letters
Answer: Around 36 letters. The fear of long words is humorously named 'hippopotomonstrosesquippedaliophobia', a word of around 36 letters. Its deliberately exhausting length makes it one of the most ironic terms in the English language.
16. What colour is a polar bear's skin underneath its fur?
- A.White
- B.Pink
- C.Black✓ Correct
- D.Grey
Answer: Black. A polar bear's skin is actually black, which helps it absorb heat from the sun. Its fur is not white but transparent and hollow, scattering light to appear white and camouflaging the bear in snow and ice.
17. How many bones does a shark have in its body?
- A.Over 200
- B.About 50
- C.Zero✓ Correct
- D.About 12
Answer: Zero. Sharks have no bones at all. Their skeletons are made entirely of cartilage — the same flexible tissue found in human ears and noses — which is lighter than bone and helps them stay buoyant and agile.
18. The Eiffel Tower can grow noticeably taller during which season?
- A.Winter
- B.Summer✓ Correct
- C.Autumn
- D.Spring
Answer: Summer. In summer, the Eiffel Tower can grow about 15 cm taller. This is because the iron structure expands as it heats up — a property of metals known as thermal expansion — and contracts again when it cools.
19. After water, which is the most consumed drink in the world?
- A.Coffee
- B.Tea✓ Correct
- C.Cola
- D.Beer
Answer: Tea. Tea is the most widely consumed beverage in the world after plain water. Originating in China thousands of years ago, it is enjoyed daily by billions of people in countless varieties and traditions.
20. Research suggests that cows form close bonds and can become stressed when separated from their what?
- A.Favourite field
- B.Best friends✓ Correct
- C.Feeding bucket
- D.Barn
Answer: Best friends. Studies have found that cows form close friendships and can become stressed, showing a higher heart rate, when separated from a preferred companion. Cows are social animals with surprisingly complex emotional lives.
21. Which is the only letter of the alphabet that does not appear in any US state name?
- A.Z
- B.Q✓ Correct
- C.X
- D.J
Answer: Q. The letter 'Q' is the only one that does not appear in the name of any US state. Even rare letters like Z (Arizona), X (Texas) and J (New Jersey) all show up somewhere.
22. Is a bolt of lightning hotter than the surface of the Sun?
- A.Yes✓ Correct
- B.No
- C.About the same
- D.Only in storms
Answer: Yes. Yes — a lightning bolt can reach about 30,000°C, roughly five times hotter than the surface of the Sun, which is around 5,500°C. The intense heat is what causes the surrounding air to expand explosively, creating thunder.
23. Which tiny creature is famous for being able to survive the vacuum of space?
- A.Ant
- B.Tardigrade (water bear)✓ Correct
- C.Mosquito
- D.Dust mite
Answer: Tardigrade (water bear). Tardigrades, also called water bears, are microscopic animals that can survive extreme conditions — including the vacuum and radiation of outer space. They do this by entering a dried-out, dormant state until conditions improve.
24. Approximately how many times does the average human heart beat in a single day?
- A.About 10,000
- B.About 100,000✓ Correct
- C.About 1 million
- D.About 5,000
Answer: About 100,000. The average human heart beats around 100,000 times a day, pumping roughly 7,500 litres of blood. Over a lifetime, that adds up to more than 2.5 billion beats.
25. The fresh smell of newly cut grass is actually a sign of what?
- A.Healthy growth
- B.A plant distress signal✓ Correct
- C.Morning dew
- D.Pollination
Answer: A plant distress signal. That pleasant 'cut grass' smell is actually a chemical distress signal. When grass is damaged, it releases compounds called green leaf volatiles, partly as a defence mechanism and to warn nearby plants.
26. Why do apples float in water?
- A.They are hollow
- B.They are about 25% air✓ Correct
- C.Their skin repels water
- D.They contain oil
Answer: They are about 25% air. Apples float because around 25% of their volume is air, making them less dense than water. This is also what makes the game of 'apple bobbing' possible.
27. What is a baby kangaroo called?
- A.A cub
- B.A joey✓ Correct
- C.A kit
- D.A pup
Answer: A joey. A baby kangaroo is called a joey. Born tiny and underdeveloped, it crawls into its mother's pouch to continue growing, feeding and staying safe for several months.
28. Wombats are unique among animals for producing droppings of which shape?
- A.Spherical
- B.Cube-shaped✓ Correct
- C.Star-shaped
- D.Flat discs
Answer: Cube-shaped. Wombats produce cube-shaped poop, the only known animal to do so. Scientists believe the unusual shape stops the droppings from rolling away, helping wombats mark their territory on slopes and logs.
29. Roughly what percentage of their DNA do humans share with bananas?
- A.About 1%
- B.About 25%
- C.About 60%✓ Correct
- D.About 95%
Answer: About 60%. Humans share roughly 50–60% of their DNA with bananas. This is because all living things rely on many of the same basic genes for fundamental cellular processes, revealing the deep connections across all life.
30. How many hearts does an earthworm have?
- A.1
- B.2
- C.5✓ Correct
- D.10
Answer: 5. Earthworms have five pairs of heart-like structures called aortic arches, which are often described simply as 'five hearts'. These pump blood through the worm's simple but effective circulatory system.
31. What is the tallest animal in the world?
- A.Elephant
- B.Giraffe✓ Correct
- C.Ostrich
- D.Polar bear
Answer: Giraffe. The giraffe is the tallest living animal, reaching up to 5.5 metres. Despite its extremely long neck, a giraffe has the same number of neck bones as a human — just seven, each greatly elongated.
32. What is the name of the surprising effect where hot water can sometimes freeze faster than cold water?
- A.The Doppler effect
- B.The Mpemba effect✓ Correct
- C.The Coriolis effect
- D.The Bernoulli effect
Answer: The Mpemba effect. The Mpemba effect describes how, under certain conditions, hot water can freeze faster than cold water. Named after a Tanzanian student who observed it, the phenomenon is still not fully explained by scientists.
33. Thanks to its protective slime, a snail can crawl across the edge of a razor blade unharmed. True or false?
- A.True✓ Correct
- B.False
- C.Only baby snails
- D.Only sea snails
Answer: True. True — a snail's thick, protective mucus allows it to glide over sharp surfaces, including the edge of a razor blade, without being cut. The slime also helps it move and prevents it from drying out.
34. Roughly how long did the shortest war in recorded history last?
- A.About 40 minutes✓ Correct
- B.About 6 hours
- C.About 3 days
- D.About 2 weeks
Answer: About 40 minutes. The Anglo-Zanzibar War of 1896 is recognised as the shortest war in history, lasting roughly 38 to 45 minutes. It ended almost as soon as it began, with a swift British bombardment.
35. Dolphins have an unusual way of sleeping. How do they do it?
- A.They don't sleep at all
- B.One half of the brain sleeps at a time✓ Correct
- C.They sleep upside down
- D.They sleep for months
Answer: One half of the brain sleeps at a time. Dolphins sleep with only half of their brain at a time, keeping the other half awake. This lets them keep surfacing to breathe and stay alert to danger, since they must consciously come up for air.
36. Which is the only type of bird that can fly backwards?
- A.Sparrow
- B.Hummingbird✓ Correct
- C.Eagle
- D.Penguin
Answer: Hummingbird. The hummingbird is the only bird able to fly backwards. Its wings beat in a rapid figure-eight pattern — up to around 80 times per second — letting it hover and even fly upside down briefly.
37. Bananas are very slightly radioactive because they contain which element?
- A.Uranium
- B.Potassium✓ Correct
- C.Radon
- D.Carbon
Answer: Potassium. Bananas are slightly radioactive due to potassium, a small fraction of which is the naturally radioactive isotope potassium-40. The amount is completely harmless — you would need to eat millions at once to be at any risk.
38. Roughly how many different scents can the human nose detect?
- A.About 100
- B.About 10,000
- C.Over 1 trillion✓ Correct
- D.About 1 million
Answer: Over 1 trillion. Research suggests the human nose can distinguish well over a trillion different smells, far more than once believed. Our sense of smell is closely linked to memory and emotion.
39. What is the collective noun for a group of lions?
- A.A pack
- B.A pride✓ Correct
- C.A herd
- D.A troop
Answer: A pride. A group of lions is called a 'pride'. Lions are the only big cats that live in social groups, with prides typically made up of related females, their cubs and a few males.
40. Octopuses have a remarkable ability to taste using which part of their body?
- A.Their eyes
- B.Their suckers (arms)✓ Correct
- C.Their fins
- D.Their tail
Answer: Their suckers (arms). Octopuses can taste with the suckers on their arms, which are packed with sensory receptors. This lets them sample their surroundings by touch, identifying food and objects without needing to see them.
41. What is the hardest substance produced by the human body?
- A.Bone
- B.Tooth enamel✓ Correct
- C.Fingernail
- D.Cartilage
Answer: Tooth enamel. Tooth enamel is the hardest substance the human body produces, even harder than bone. It protects the teeth, but unlike bone it cannot repair or regrow itself once it is damaged.
42. Is the length of a day on Earth gradually getting longer over time?
- A.Yes, very slowly✓ Correct
- B.No, it stays exactly the same
- C.No, it's getting shorter
- D.Only in winter
Answer: Yes, very slowly. Yes — Earth's rotation is gradually slowing due to tidal friction caused by the Moon, making each day very slightly longer over time. The change is tiny, on the order of milliseconds per century.
43. Which animal has fingerprints so similar to humans' that they can be confused at a crime scene?
- A.Chimpanzee
- B.Koala✓ Correct
- C.Gorilla
- D.Raccoon
Answer: Koala. Koalas have fingerprints almost indistinguishable from human ones, even under a microscope. This is a striking example of convergent evolution, as koalas and humans are only very distantly related.
44. What is the name for the small dot that appears above a lowercase 'i' or 'j'?
- A.A serif
- B.A tittle✓ Correct
- C.An umlaut
- D.A caret
Answer: A tittle. The dot above a lowercase 'i' or 'j' is called a 'tittle'. The word comes from the same root as 'title' and originally meant a small mark used in writing.
45. Which amphibian is famous for its remarkable ability to regrow lost limbs?
- A.Frog
- B.Axolotl✓ Correct
- C.Toad
- D.Newt
Answer: Axolotl. The axolotl, a type of salamander, can regrow entire lost limbs, parts of its heart and even sections of its brain. Scientists study it closely in the hope of unlocking secrets of tissue regeneration.
46. Which animal is considered the loudest on Earth?
- A.Lion
- B.Blue whale✓ Correct
- C.Howler monkey
- D.Elephant
Answer: Blue whale. The blue whale is among the loudest animals on Earth, producing calls that can exceed 180 decibels — louder than a jet engine. These low-frequency sounds can travel hundreds of kilometres through the ocean.
47. What is the common name for frozen carbon dioxide?
- A.Black ice
- B.Dry ice✓ Correct
- C.Glacier ice
- D.Hard water
Answer: Dry ice. Frozen carbon dioxide is called 'dry ice'. Instead of melting into a liquid, it sublimates — turning directly into a gas — which is why it produces a dramatic fog and leaves no puddle behind.
48. What is one of the collective nouns for a group of jellyfish?
- A.A smack✓ Correct
- B.A clutch
- C.A gaggle
- D.A pod
Answer: A smack. A group of jellyfish can be called a 'smack' (they are also referred to as a 'bloom' or 'swarm'). Large blooms can contain thousands of jellyfish drifting together on ocean currents.
49. Which is the only continent with no native species of snake?
- A.Australia
- B.Antarctica✓ Correct
- C.Europe
- D.South America
Answer: Antarctica. Antarctica has no native snakes — the continent is far too cold for these cold-blooded reptiles to survive. Snakes are found on every other continent on Earth.
50. Is it true that goldfish have a memory of only a few seconds?
- A.True
- B.False — they can remember for months✓ Correct
- C.True, exactly 3 seconds
- D.Only as adults
Answer: False — they can remember for months. It's false — the idea that goldfish have a three-second memory is a myth. Studies show goldfish can actually remember things for weeks or even months, and they can be trained to respond to signals and routines.
