Reading - missing paragraphs

This is another reading passage to practise this part of the exam.

Read the whole text first to have a general idea of its content.  Then pay attention to the last sentence before a gap and to the first sentence after a gap, and try to establish a connection with the missing paragraphs at the bottom of the text.  Remember that a text is a unit and that every paragraph has a connection with both, the previous and the following one.
