There are 11 pdf files in all, all printed using dopdf - http://www.dopdf.com
The pdfs are based on a Mix and Gap file containing the text of the article, which is also included (mtx3). This file provides a wide variety of interactive exercises for use with PCs or with an interactive whiteboard. It requires TaskMagic3. If you haven't got TaskMagic3, you can download a 30-day trial from the TaskMagic website (doesn't require registration or anything - just download and install it).
The screenshot shows the student front page for the file in TaskMagicPlay. In TaskMagic, each of the little thumbnails links to a different interactive exercise.
It takes a matter of minutes to convert any news article like this one into a load of worksheets and interactive resources which recycle the same content in lots of different ways.
