This question was phrased by the source as follows:"On these cards you can see a number of different internet activities, things one can do in the internet. Please organize the cards on this sheet depending on how often you engage in these activities on the internet: writing comments on articles by journalists, for example on the homepage of a newspaper or a magazine, or on the blog of a journalist."

Bitte verteilen Sie die Karten entsprechend auf das Blatt, je nachdem, wie häufig Sie das im Internet machen. - Kommentare zu Artikeln von Journalisten schreiben, z.B. auf der Internetseite einer Zeitung oder Zeitschrift oder im Blog eines Journalisten.")
