Imagine that you are doing a project on how much teenagers sleep on weekdays in Zetland. You have found some data on the subject - the results of the opinion polls (see the table below).

8-9	7

Write 200-250 words.

Use the following plan:

— make an opening statement on the subject of the project;

— select and report 2–3 facts;

— make 1–2 comparisons where relevant and give your comments;

— outline a problem that can arise with teenagers' health and suggest a way of solving it;
