Solutions

1:B - First the tree gets chopped up into little chips, then these chips are softened into a mushy pulp by using chemicals that break down the fibres or by grinding them with machinery. This pulp is then washed, bleached, spread out flat and dried, making paper., 2:D - Plants can’t run away from potential predators, so some have become poisonous for self-defence. This puts animals off munching them!, 3:C - The moon doesn’t create its own light, but reflects light from the sun off its surface, which is why we’re able to see it. The moon is bright enough that you can see it during the day or night, as long as it’s in the right part of the sky., 4:B - The deepest hole humans have managed to dig is the Kola Superdeep Borehole in Russia, which is 12,262 metres deep – deeper than Mount Everest is tall., 5:A - According to the US Department of Agriculture, there were about 1 billion cows in 2022, but the Food and Agriculture Organisation estimates there are closer to 1.5 billion cows worldwide! That’s a lot of cowpats.
