Question 1 — Science

🎯 What is the speed of light in a vacuum, to the nearest thousand km/s?

200,000 km/s

300,000 km/s

400,000 km/s

150,000 km/s

Light travels at approximately 299,792 km/s in a vacuum — commonly rounded to 300,000 km/s. Einstein's special relativity establishes this as the universal speed limit.

Question 2 — History

🎯 In which year did the Berlin Wall fall?

1987

1991

1989

1993

The Berlin Wall fell on 9 November 1989, after 28 years of dividing East and West Berlin. It is widely considered one of the defining moments of the end of the Cold War.

Question 3 — Technology

🎯 Which company developed the Python programming language?

MIT

Bell Labs

Sun Microsystems

No company — created by Guido van Rossum independently

Python was created by Guido van Rossum and first released in 1991. He developed it independently while working at Centrum Wiskunde & Informatica in the Netherlands. It was not a corporate project.

Question 4 — Geography

🎯 Which country has the longest coastline in the world?

Russia

Australia

Canada

Norway

Canada has the world's longest coastline at approximately 202,080 km — including its mainland and offshore islands. Its coastline is so long it would wrap around the Earth more than five times.

Question 5 — Science

🎯 What is the most abundant gas in Earth's atmosphere?

Oxygen (O₂)

Carbon dioxide (CO₂)

Argon (Ar)

Nitrogen (N₂)

Nitrogen makes up about 78% of Earth's atmosphere. Oxygen accounts for roughly 21%, with argon at 0.93% and carbon dioxide at only 0.04%. Many people assume oxygen is the most abundant because we breathe it.

Question 6 — Technology

🎯 What does 'HTTP' stand for?

Hypertext Transfer Protocol

Hybrid Text Transmission Program

Hyperlink and Text Transport Process

High-level Text Transfer Protocol

HTTP stands for HyperText Transfer Protocol. It is the foundation of data communication on the World Wide Web, defining how messages are formatted and transmitted between web browsers and servers.

Question 7 — History

🎯 Who was the first person to walk on the Moon?

Buzz Aldrin

Yuri Gagarin

Neil Armstrong

Michael Collins

Neil Armstrong became the first human to walk on the Moon on 20 July 1969 during the Apollo 11 mission. His words — 'one small step for man, one giant leap for mankind' — are among the most quoted in history.

Question 8 — Mathematics

🎯 What is the value of π (pi) to four decimal places?

3.1416

3.1514

3.1428

3.1592

Pi (π) is approximately 3.14159265… — rounded to four decimal places it is 3.1416. It represents the ratio of a circle's circumference to its diameter and is one of the most important constants in mathematics.

Question 9 — Science

🎯 How many bones does an adult human body have?

306

206

186

256

An adult human body has 206 bones. Babies are born with around 270–300 bones, but many fuse together during childhood and adolescence, resulting in the adult count of 206.

Question 10 — Technology

🎯 Which data structure operates on a 'first in, first out' (FIFO) principle?

Stack

Tree

Queue

Heap

A Queue is a FIFO (First In, First Out) data structure — elements are added at the rear and removed from the front, like a queue at a checkout. A Stack is the opposite: LIFO (Last In, First Out).
