The dangers of cross-cultural plagiarism

I'm doing a bit of textbook editing on the side. As is usual here, the material is mostly cribbed from elsewhere with the questions sometimes done by the "writer" and sometimes themselves cribbed from elsewhere.

This can lead to disaster as it would have been in this case had they not asked me to do some editing for them.

In one section of the book there's an activity to make a restaurant menu. They have a sample menu at the top of the page as a model. Here's what the model menu says:
