23. TapescriptTapescript 1. Well, that’s very interesting question. It is already possible to make artificial organs and parts of the body-but it won’t be possible for a very long time to make artificial humans, known as androids, that can think or feel in the same way as we do.

24. 2. We know that the planet’s climate is changing. The Earth’s atmosphere is gradually getting warmer. There is a real danger that the sea level will go up and there will be flooding in different countries in the world. This is already happening in countries like Bangladesh and some parts of Europe, for example, Britain.

25. 3. Well, it may sound surprising. Imagine the situation of two twins-a brother and sister. The sister goes into space and travels at the speed of light for ten years-when she comes back to Earth she is thirty years older than her twin brother!

26. 4. Unfortunately, this is a very real danger for the planet. A new virus could develop that we have no power to stop. It is something we really should be worried about.
