1. 1.The camel is called the ship of the desert. It can walk for many days on hot sand without drinking water. Its long eyelashes protect its eyes from blowing sand. Its wide, flat feet do not sink into the sand. The hump on its back stores fat, not water. In India, camels are found in the deserts of Rajasthan.
   
   Why don’t a camel’s feet sink into the sand? (a) They have claws (b) They are wide and flat (c) They are wet (d) They are very small
2. 2.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) drinking water (b) reading in dim light (c) sleeping early (d) washing hands
3. 3.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.
   
   Why does the Moon shine? (a) it is made of ice (b) it has lamps (c) sunlight bounces off it (d) it is on fire
4. 4.Butterflies begin their life as tiny eggs on leaves. A caterpillar hatches from each egg. The caterpillar eats leaves all day and grows bigger and bigger. Then it makes a hard case around itself called a pupa. Inside the pupa, the caterpillar slowly changes. After some days, a beautiful butterfly comes out and flies away.
   
   What does the caterpillar eat? (a) insects (b) leaves (c) flowers (d) seeds
5. 5.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. Elephants have big ears that flap to keep them cool. They live in groups led by the oldest female. In India, elephants live in forests in Kerala, Karnataka, Assam and other states.
   
   Who leads a group of elephants? (a) the youngest calf (b) the biggest male (c) the oldest female (d) a tiger
6. 6.Plants make their own food in their leaves. To do this, they need sunlight, water and air. The roots take in water from the soil. The green colour in the leaves helps them catch sunlight. Animals cannot make their own food like plants do. That is why plants are very important for all living things.
   
   What helps leaves catch sunlight? (a) the green colour (b) the roots (c) the soil (d) the rain
7. 7.Our heart is a strong muscle about the size of our fist. It works like a pump and pushes blood all around the body. The heart never stops, even when we are asleep. Blood carries food and oxygen to every part of the body. When we run or play, our heart beats faster. Doctors listen to the heartbeat with a stethoscope.
   
   How big is our heart? (a) the size of a ball (b) the size of our fist (c) the size of a pea (d) the size of our head
8. 8.Plants make their own food in their leaves. To do this, they need sunlight, water and air. The roots take in water from the soil. The green colour in the leaves helps them catch sunlight. Animals cannot make their own food like plants do. That is why plants are very important for all living things.
   
   Which of these do plants need to make food? (a) salt (b) sunlight (c) sand (d) darkness
9. 9.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 year (b) about a day (c) about a month (d) about a week
10. 10.Rain begins with the Sun heating water in seas, rivers and lakes. The warm water turns into water vapour and rises into the sky. High up, the air is cold, so the vapour cools and forms tiny drops. Many drops join together to make clouds. When the drops become too heavy, they fall as rain. This journey of water is called the water cycle.
    
    Why do the drops fall as rain? (a) The wind pushes them (b) They become too cold (c) The Sun pulls them (d) They become too heavy
11. 11.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.
    
    How many milk teeth do children have? (a) ten (b) thirty (c) sixteen (d) twenty
