About This Quiz

The world is indeed a strange place.

Sometimes, you cannot actually believe some of the true facts that pertain to our world, its people and the fauna and flora that we find on our beautiful planet. 

For instance, did you know that earth is the only planet not named after a god? What about the fact that "hello" wasn't a greeting used until the telephone came along. And who introduced it? Thomas Edison. Although, the inventor of the telephone wanted the greeting to be "Ahoy!" Let's all just agree that "Ahoy" is infinitely cooler!

Or did you know that elephants can't jump (which let's be honest, seems pretty logical)? Sticking with the animal world, a tarantula (shudder!) can live without food for 24 months and the tongue of a blue whale is heavier than an African elephant. 

Interesting facts, right? And you will find many more in our quiz. Except you have to answer them. Do you think you can do it? Some are extremely difficult, so a score of 21 out of 35 will be excellent. 

So what you waiting for! Jump right in and show us what you are made of! You got this!

Good luck, and enjoy it!
