Since this IS a foreign language textbook, the situation is different than it would be for your other question, which involves only the translated glossary in what is a textbook in English. Furthermore, this print layout is not something I have seen before. I am going to ask others about it. In the meantime, I am considering your other question about the translated glossary in the English textbook.
Thank you for the extra effort of sending the print pages. I would not be able to answer this without them.
I appreciate your patience.
