I meant FCE- I'm a bad typist.
You can ignore addresses in letters, but reports should look like reports, so headings are appropriate. Given the definition in your book, you have carried out the task well. When they ask, say, for a brochure, it should not just have a body text, but should have headings, etc. As I understand it,the reason they dropped addresses was to stop students writing huge addresses and taking up too many words. In a true report, there would be no call for 'God bless, Mr Corey', but in a newspaper report, this would be fine.
