Solutions

1:C - Sloths hang upside down mainly to conserve energy, and to help them reach the leaves that are easy to digest. Unlike humans, their bodies are adapted to work well upside down for 90% of the day., 2:B - Well, it was 11.44 when I was writing this answer, in France! A lot of time has passed since then. There are complex answers from physicists and philosophers but, put simply, time is a way for us to measure how long things take, using clocks and calendars., 3:D - Numbers go on infinitely, but in 2025 Favour Ogechi Ani from Nigeria broke a world record by counting aloud to 1,070,000 over 70 consecutive days., 4:A - The Earth orbits the sun and rotates, but it’s on a tilt of about 23.5 degrees. When the northern hemisphere, including the UK, is angled towards the sun, it’s our summer. When it’s tilted away from the sun, temperatures are colder., 5:D - A gamma ray is the highest-energy type of electromagnetic radiation. It is produced through the decay of an atomic nucleus (centre of an atom), or during solar flares in space.
