Solutions

1:D - The Romans named the five planets they could see after gods and goddesses (Jupiter, Mars, Saturn, Mercury and Venus). Most cultures had names for these planets, but early astronomers in Europe wrote in Latin, the language of the Roman empire – so they used the Roman names., 2:A - It’s hard to know for sure which was the first musical instrument, but flutes made from animal bones have been found in Germany – they date back 30,000 to 40,000 years., 3:D - Noses are useful for breathing, smelling, filtering out bad stuff like dust and pollen, and warming the air we take in, because dry, cold air can irritate the lungs., 4:B - If you add together the islands recorded by each country, there are roughly 900,000 officially reported islands. Scientists believe that there are many more unrecorded., 5:C - Animals including some birds, reptiles and sea lions swallow rocks to help them grind their food – useful if they don’t have teeth. Once swallowed, these stones are called “gastroliths” – stomach stones! They’re used to help digest food.
