Wrong!

It was Alexander Fleming!

The first true antibiotic was discovered accidentally by Fleming in 1928 when he returned from a holiday to find mould growing in a petri dish of bacteria. The mould had inhibited bacterial growth surrounding it, suggesting it might be capable of fighting a range of harmful bacterial infections like pneumonia, gonorrhoea, and rheumatic fever!

Wrong!

It's vibrate!

Verbs are most often defined as "doing words" which describe an action, like "running" or "singing", but they can also be used to describe a state of being or an occurrence. Words like "is" and "became" are also verbs, for instance. Confusing, right?

3. Where is the kidney in the human body?

Wrong!

It's A!

Your kidneys sit on either side of your spine, below your ribs, and behind your stomach. They are about the size of a fist and are shaped like a bean. Their job is to filter blood by removing waste and monitoring levels of electrolytes, salt, water, and minerals in the bloodstream.

4. What is an integer?

Correct!
Wrong!

It's a whole number!

An integer is a whole number, not decimal or fraction.

5. Which of these is NOT a prime number?

Getty
Correct!
Wrong!

It's 42!

Prime numbers are actually super simple â€“ they are integers that can only be divided into other integers by themselves and by 1! E.g. 19 cannot divided by any number that isn't itself or 1, whereas 42 can be divided by 2 to get 21.

6. What is a normal human heart rate?

Getty
Correct!
Wrong!

It's between 60 and 100 beats per minute!

Most adults have a heart rate the falls in between this range, but the fitter among us may have a slower heart rate as low as 40 bpm.

7. Which of these countries is NOT in Asia?

Getty
Correct!
Wrong!

It's Burundi!

There are 48 countries in Asia, but Burundi is not one of them. You will find this country in East Africa, south of the Equator.

8. Where is Stonehenge?

Getty
Correct!
Wrong!

It's Wiltshire!

Stonehenge is a prehistoric stone circle monument and UNESCO World Heritage site located about 8 miles north of Salisbury, Wiltshire, England. It's believed to have taken Neolithic builders over 1,500 years to erect and is made up of around 100 huge upright stone slabs.

9. How many oceans are there on Earth?

Getty
Correct!
Wrong!

It's five!

There is technically one "world ocean", since every ocean is connected to at least two others; however, most modern-day scientists have come to understand the vast body of water that covers our planet in terms of five regions, or ocean basins. These basins are known as The Pacific, Atlantic, Indian, Arctic, and Southern (Antarctic) oceans.

10. Which of these is a compound word?

Getty
Correct!
Wrong!

It's starfish!

Again, compound words are super easy to understand â€“ they are literally just two words joined together to make a new word with a new meaning! They can either be written as two words (an open compound), one word (a closed compound), or as two words which are hypenated (hyphenated compounds).

11. Click on pi to five decimal places:

Getty
Correct!
Wrong!

It's 3.14159.

Pi, or Ï€, is the most famous mathematical constant in the world. In basic maths, it is used to calculate the area and circumference of a circle. It is an irrational number, meaning that after the decimal point, the digits go on forever. Pi has been around for nearly 4,000 years and is even referenced in The Bible!

12. How many people have walked on the moon?

Getty
Correct!
Wrong!

It's 12!

Between the years of 1969 to 1972, twelve men stepped foot on the moon aboard lunar landing missions Apollo 11, 12, 14, 15, 16, and 17. No manned mission to the moon has taken place since, and thus far, no women have ever set foot on the moon.

13. During which years was Queen Victoria alive?

Getty
Correct!
Wrong!

It's 1819â€“1901!

Until recently, Queen Victoria was our longest-ruling monarch (1837â€“1901). She was born in 1819 and coronated at the age of 18. Her reign, known as the Victorian era, is often taught in British schools due to the vital changes in industry, culture, science, and the British Empire that occurred during this time.

14. What is a factor?

Getty
Correct!
Wrong!

In mathematics, a factor is any number that will divide exactly into another number. For instance, take the number 12 for example â€“ its factors are 1, 2, 3, 4, 6 and 12. These numbers all divide into 12 without any remainders. 5 is not a factor of 12 because it cannot be divided into 12 exactly.

15. Which of these is a preposition?

Getty
Correct!
Wrong!

It's behind!

Prepositions set up the relationship between other words â€“ usually nouns â€“ in a sentence in terms of where and when things exist. Words like "behind", "at", "in", and "under" are prepositions.

16. Where did the Vikings come from?

Getty
Correct!
Wrong!

The Vikings originated in southern Scandinavia. In modern day terms, this region roughly covers the three kingdoms of Denmark, Norway, and Sweden.

17. Click on the proper use of a semicolon:

Getty
Correct!
Wrong!

A semicolon is somewhere in between a comma and a full stop. They are used to join two related yet independent clauses without using a conjunction like "but", and they are also used in complicated lists where commas just won't cut it. You shouldn't use a semicolon AND a conjunction, and you don't need to capitalise the word after a semicolon unless it's a proper noun or an acronym.

18. What does GDP stand for?

Getty
Correct!
Wrong!

In economic terms, GDP is a measure used to assess a country's overall economic health. There are three ways to calculate GDP, and these include either the total monetary value of all finished goods and services that a country has produced; the income of the total population of a country; or the total expenditure of an entire population over a specific period of time.

19. Click on the polygon:

Getty
Correct!
Wrong!

It's B!

A polygon is simply a two-dimension shape with straight sides, including triangles, rectangles, and pentagons. A circle, for example, is not a polygon because it has one curved side.

20. What is this fraction as a decimal?
4/5.

Getty
Correct!
Wrong!

It's 0.8 !

An easy way to convert fractions into decimals is to divide the numerator (the top figure) by the denominator (the bottom figure). This is because the line in a fraction basically represents division.
