Question
Read the text again and answer the questions.
Answer
It is very hot, there is little water and the soil is no good for growing crops. There are also lots of insects.
They live day to day and do not have permanent homes. Also, I think that their way of living must be quite dangerous and that is why they don't become attached to people or things.
Life is very difficult for them and they may not be able to survive this way for much longer.
