Questions 25-29. What paragraphs are the notes referring to? Write the letter of the correct paragraph. 

A 

Earth is our home, but it's possible that we will populate our moon one day. We first visited the moon in 1969, and now scientists are talking about going to live there. That will be a huge achievement because there are many difficulties for humans to deal with on the moon. 

B 

Obviously, we will need air to breathe. And air is also important because it protects us from radiation - a dangerous energy from the sun. Without air, radiation can kill. The moon has no atmosphere, so we will need to make our own air there before the moon is a suitable home. 

C 

Of course, we will also need food and water. Again, the moon doesn't have these things, and we won't want to bring them from Earth because space travel is very expensive. Did you know, for example, that sending a one-liter bottle of water into space costs over $20,000? So people will have to recycle water and grow food on the moon. 

D 

There is another problem that people on the moon might have. At first, homes and towns on the moon will be very small. People will have to live in these small spaces and it will be difficult for them to ever be alone. Like many animals, humans find it difficult to always be near others. 

Studies show that crowded places cause stress, and there is a greater chance of people there having physical or mental illnesses. 

E 

Although we will have to deal with problems on the moon, they are things that we will probably solve quite quickly. We will learn from the experience, and who knows, perhaps our great grandchildren will travel to other galaxies, or even live on distant stars.
