• Paragraph 2: Of course, the tortoises in Austria aren't the first animals to use this technology. More than thirty years ago, a male bonobo monkey called Kanzi learned how to use a large touch-screen to communicate... -> E Say it with pictures
• Paragraph 3: Scientist Jennifer Vonk also uses touch-screens with the animals she studies. A few years ago, she did an experiment with three young black bears... she found that the bears could count just like animals in groups... -> A Knowing their numbers
• Paragraph 4: But animals don't only use touch-screens in experiments. The penguins at a zoo near Los Angeles have a tablet that they use for entertainment... The game exercises their minds and helps to make their lives in the zoo more interesting. -> D Passing the time
