False! While massive, its sister ship, the RMS Olympic, was slightly heavier. The Titanic was the largest *during its maiden voyage* due to last-minute modifications.
Question 6:
Kangaroos can walk backward.
False! Their tail and leg structure make it biomechanically impossible for kangaroos to walk or hop backward.

The capital of Australia is Sydney.
False! Canberra is the capital, chosen as a compromise between rivals Sydney and Melbourne in 1908.
Question 8:
Honey never spoils.

Question 10:
The Amazon Rainforest produces 20% of the world’s oxygen.
False! While vital for biodiversity, most of Earth’s oxygen comes from marine phytoplankton. The Amazon’s net oxygen output is near zero due to respiration by plants and animals.
Question 11:
Einstein failed math in school.
False! This myth persists, but Einstein excelled in math from a young age. He did struggle with the rigid structure of schooling early on.
Question 12:
Polar bears have black skin.
True! Their fur is translucent (appearing white due to light reflection), but their skin is black to better absorb heat from sunlight.

True! This term also applies to the dot on 'j' and diacritical marks in other languages.
Question 15:
The first computer virus was created in the 1980s.
False! The first self-replicating program, 'Creeper,' appeared in 1971. The term 'virus' was coined later.
Question 16:
Cleopatra lived closer to the invention of the iPhone than to the building of the Great Pyramid.
True! Cleopatra (69–30 BCE) lived ~2,500 years after the Great Pyramid (~2560 BCE) but only ~2,000 years before the iPhone (2007).
Question 17:
The tongue is the strongest muscle in the human body.
False! The tongue is a group of muscles, but the masseter (jaw muscle) is the strongest relative to size. The uterus is arguably the most powerful overall.
