1. 1.The Sun is a star, the closest one to Earth. It is a huge ball of very hot gases. The Sun gives us light and heat. Without the Sun, there would be no plants, animals or people on Earth. The Sun looks small only because it is very far away. We must never look straight at the Sun, because it can hurt our eyes.
   
   Which two things does the Sun give us? (a) wind and clouds (b) rain and snow (c) food and water (d) light and heat
2. 2.The Moon is Earth’s closest neighbour in space. It does not make its own light. The Moon shines because sunlight falls on it and bounces off. As the Moon goes around Earth, we see different shapes of it. On a full moon night, we see the whole round Moon. On a new moon night, we cannot see the Moon at all. It takes about a month for the Moon to go around Earth.
   
   How long does the Moon take to go around Earth? (a) about a day (b) about a month (c) about a year (d) about a week
3. 3.Water can be found in three forms. When water freezes, it becomes solid ice. When ice melts, it turns back into liquid water. When water is heated, it turns into steam, which is a gas. We use ice to keep drinks cold on hot days. Clouds are formed when water vapour cools high up in the sky.
   
   What does water become when it freezes? (a) rain (b) steam (c) clouds (d) ice
4. 4.The peacock is the national bird of India. The male peacock has a long tail with shining blue and green feathers. Each feather has a pattern that looks like an eye. When it rains, the peacock often spreads its tail and dances. The female, called a peahen, is brown and has no long tail. Peacocks eat seeds, insects and even small snakes.
   
   True or false: The peahen has a long tail. (a) False (b) True
5. 5.Winds are moving air. A gentle wind is called a breeze, and it feels pleasant on a hot day. A very strong wind with heavy rain is called a storm. A cyclone is a huge storm that forms over the sea and can damage houses and trees. Before a cyclone, the weather office warns people near the coast. People then move to safe places until the cyclone passes.
   
   What does “gentle” mean in the passage? (a) very cold (b) soft and mild (c) very strong (d) very loud
6. 6.A seed has a baby plant inside it. When a seed gets water, air and warmth, it starts to grow. This is called germination. First, a tiny root grows down into the soil. Then a small shoot grows up towards the light. Soon the first green leaves open. You can watch this happen by keeping a few moong seeds on wet cotton.
   
   What grows first from the seed? (a) a flower (b) a leaf (c) a shoot (d) a tiny root
7. 7.Our teeth help us bite and chew food. Children have twenty milk teeth, which fall out one by one. New, stronger teeth grow in their place. Sugary food and sticky sweets can cause holes in our teeth. So we should brush our teeth twice a day, in the morning and at night. We should also rinse our mouth with water after every meal.
   
   What grows in place of the milk teeth? (a) soft teeth (b) no teeth (c) stronger teeth (d) more milk teeth
8. 8.Elephants are the largest animals that live on land. An elephant uses its long trunk to breathe, smell, drink and pick up food. It sucks water into its trunk and then sprays it into its mouth.

   Who leads a group of elephants? (a) a tiger (b) the youngest calf (c) the biggest male (d) the oldest female
9. 9.Our eyes help us see colours, shapes and light. Our ears help us hear sounds. We smell with our nose and taste with our tongue. Our skin helps us feel if something is hot, cold, rough or smooth. These five are called our sense organs. We must take care of them, for example, by not reading in dim light.
   
   What should we not do, according to the passage? (a) washing hands (b) drinking water (c) sleeping early (d) reading in dim light
