Reading tip (Find the key word): Pick the key word in the question (roots, honey, clouds). Find that word in the passage. Read that sentence carefully — it holds the answer.

1. 1.Frogs can live both in water and on land. A frog lays its eggs in water. Tadpoles come out of the eggs and swim with their tails, like tiny fish. Slowly, they grow legs and lose their tails. Then they hop out of the water as young frogs. Frogs catch insects with their long, sticky tongues. In the monsoon, you can hear them croaking loudly.
   
   Where does a frog lay its eggs? (a) on land (b) in water (c) in nests (d) in trees
2. 2.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 should we do after every meal? (a) brush our hair (b) eat sweets (c) rinse our mouth (d) sleep
3. 3.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) leaves (b) flowers (c) seeds (d) insects
4. 4.Honeybees live together in a home called a hive. A hive has one queen bee, who lays all the eggs. The worker bees collect nectar from flowers and turn it into honey. They also clean the hive and look after the young bees. When a bee finds flowers, it does a special dance to tell the others where to go. Bees also help plants by carrying pollen from flower to flower.
   
   What is the home of honeybees called? (a) a nest (b) a den (c) a burrow (d) a hive
5. 5.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) more milk teeth (b) no teeth (c) stronger teeth (d) soft teeth
6. 6.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) clouds (c) ice (d) steam
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.
   
   When does our heart beat faster? (a) when we sit (b) when we read (c) when we run or play (d) when we sleep
8. 8.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) sleeping early (c) reading in dim light (d) drinking water
9. 9.Ants are tiny insects, but they are very strong. An ant can carry things much heavier than its own body. Ants live together in large groups called colonies. Some ants build their homes under the ground, with many rooms and tunnels. When an ant finds food, it leaves a smell trail. Other ants follow this trail to reach the food.
   
   What are large groups of ants called? (a) colonies (b) hives (c) flocks (d) herds
10. 10.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.
    
    Where are butterfly eggs laid? (a) on leaves (b) under stones (c) in water (d) in nests
11. 11.Trees are very useful to us. They give us fruits, wood and shade. Trees take in the air we breathe out and give out oxygen, the gas we need to live. Their roots hold the soil together, so it is not washed away by rain. Birds build nests in trees, and many insects live on them. That is why we should plant more trees and not cut them down.
    
    What is the main idea of the passage? (a) Trees are very useful (b) Rain washes soil (c) Insects are small (d) Birds build nests
12. 12.Trees are very useful to us. They give us fruits, wood and shade. Trees take in the air we breathe out and give out oxygen, the gas we need to live. Their roots hold the soil together, so it is not washed away by rain. Birds build nests in trees, and many insects live on them. That is why we should plant more trees and not cut them down.
    
    Who builds nests in trees? (a) frogs (b) fish (c) birds (d) cows
