Read the following passage carefully and answer the question that follows. Have you ever played with your shadow on a sunny day? It’s one of the most interesting things around us! A shadow is made when something blocks the light. When you stand in sunlight, your body blocks the light and makes a dark shape on the ground. That’s your shadow! What makes it so fun is how it moves with you. Try jumping—your shadow jumps too! Wave your hand, and your shadow waves back. But shadows can be sneaky too. In the morning, they are long. At noon, they become short. In the evening, they stretch again. Some children make shadow puppets using a torch and their hands. You can make birds, dogs, and even dragons! Shadows are like silent friends who copy everything you do. Isn’t that fun and amazing? Next time you go outside, don’t forget to say hello to your shadow! Question: Why does the passage call shadows ‘silent friends’?

1. They change their colour depending on light.
2. They copy our actions without making a sound.
3. They are always visible during the day.
4. They never move away from us.
