0:00 Greeting's Trivia fans. I'm Mark Allison, and we're wrapping up the week with some fascinating general knowledge. Question one, What everyday item was invented by Swiss engineer George de Mestral after he examined burrs stuck to his dog's fur under a microscope. Question two? Which animal has the longest gestation period of any land mammal, carrying its young for up to twenty two months? Question three? What percentage of the world's oxygen is produced by the Amazon rainforest? Question four?
0:41 Which country consumes the most coffee per capita in the world? Question five? What is the only metal that's liquid at room temperature. We'll be right back with these fascinating answers after this break. Welcome back, trivia fans. Let's reveal today's answers. Question one. What item was inspired by? Burs on a dog? Answer? Velcrow. In nineteen forty one, George de Mastral returned from a hunting trip and noticed how tenaciously burs clung to his dog's fur. Under a microscope, he saw the burs had tiny hooks that caught on loops and fabric and fur, inspiring his invention of the hook and loop fastener we now call felcrow. Question two, which animal has the longest gestation period? Answer the African elephant. Female elephants carry their calves for approximately twenty two months before giving birth, the longest pregnancy of any land mammal. This extended development time allows elephant calves to be born with advanced brain development.
1:50 Question three. What percentage of oxygen comes from the Amazon? Answer twenty percent. The Amazon rainforest, often called the lungs of the planet, produces about twenty percent of Earth's oxygen through photosynthesis. This massive ecosystem covers about two point six million square miles across nine South American countries. Question four Which country consumes the most coffee per capita? Answer Finland. The average finn consumes about twenty six zero point five pounds of coffee per year, which equals approximately three to four cups per day. The harsh climate and long dark winters contribute to Finland's coffee culture. Question five. What metal is liquid at room temperature? Answer mercury. With a melting point of negative thirty eight point eighty three degrees celsius, mercury is liquid at normal room temperature. This unique property made it valuable for thermometers and barometers before its toxicity became better understood. That concludes today's five daily trivia questions.
