Solutions

1:C - The biggest coin that you can legally use in shops is the Kangaroo One Tonne Gold Coin from Australia. It’s 80 centimetres across and weighs more than 1,000 kilograms. It has a face value of 1 million Australian dollars, but the gold itself is worth much more., 2:C - Oval blood cells help camels cope with extreme dehydration by keeping blood flowing when water is scarce, but the speed of bleeding depends on blood pressure and the size of the cut, not cell shape., 3:B - Tickling triggers your brain to make you laugh – but some people don’t if they’re expecting it, or if their brain reacts differently., 4:D - Measured on bite force, all these could be considered the strongest prehistoric animal. T rex wins for land bite force, Deinosuchus may have had an even more powerful bite in water, and Dunkleosteus was the bite champion of the fish world., 5:C - About 30,000–45,000 lions. There are 20,000-25,000 lions in the wild, according to World Wide Fund for Nature, plus an estimated 10,000–20,000 living in captivity in zoos, sanctuaries and lion farms.
