Does anyone know this book?

Hi!! I'm learning German (starting B1 right now) and our teacher uses a book for us to practice but he has never / doesn' want to tell us what's its name. So if anyone knows which one it is, I'd appreciate it very much because I want to do some exercices before our exam. Thank you! I'm adding some pictures of the exercises and the answers. I hope someone can recognize it haha Example of the book answers Example of some exercises submitted by /u/Mrs_Nesbittt [link] [comments]
