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.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 do worker bees collect from flowers? (a) nectar (b) water (c) seeds (d) leaves
2. 2.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) fish (b) cows (c) frogs (d) birds
3. 3.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.
   
   What is the national bird of India? (a) the crow (b) the peacock (c) the parrot (d) the sparrow
4. 4.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.
   
   What do doctors use to listen to the heartbeat? (a) a mirror (b) a torch (c) a thermometer (d) a stethoscope
5. 5.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 hatches from a butterfly egg? (a) a butterfly (b) a caterpillar (c) a bee (d) a worm
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 cools high up in the sky to form clouds? (a) smoke (b) dust (c) ice (d) water vapour
7. 7.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.
   
   True or false: The Moon makes its own light. (a) True (b) False
8. 8.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.
   
   What colour is a peahen? (a) green (b) blue (c) white (d) brown
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.
   
   Which word is the opposite of “rough”? (a) hot (b) cold (c) dim (d) smooth
10. 10.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 on fire (b) it has lamps (c) it is made of ice (d) sunlight bounces off it
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.
    
    What grows in place of the milk teeth? (a) more milk teeth (b) stronger teeth (c) no teeth (d) soft teeth
12. 12.Magnets can pull things made of iron and steel. This pull is called attraction. A magnet cannot pull wood, paper, plastic or glass. Every magnet has two ends called poles: a north pole and a south pole. Two north poles push each other away. A north pole and a south pole pull each other close. Magnets are used in toys, fridge doors and compasses.
    
    True or false: A magnet can pull a plastic ruler. (a) True (b) False
