Solutions

1:C - Skyscrapers, the tall, modern buildings you see in cities, came about in the 1880s. “Skyscraper” was first used to describe buildings that had 10 to 20 platforms or “storeys”, but now it means they have more than 40 floors. The Burj Khalifa in Dubai has 163! , 2:B - The Earth is always orbiting (moving around) the sun, but its average distance to the sun is about 150 million kilometres. , 3:A - Humans take about 20,000-25,000 breaths each day, about 7.5 million- 9 million breaths a year. , 4:B - Lightning is an electrical release caused by imbalances between the storm clouds and the ground, or within clouds themselves. During a storm particles of rain, ice or snow inside clouds give them a negative charge, and objects on the ground such as trees gain a positive charge. The difference between these charges causes lightning to be released to bring things back into balance., 5:B - Grazing the skin causes a little bit of the top skin layer to be removed and exposes the many fine nerve endings in the skin. Even hot water can make them hurt.
