This is a short-and-sweet 10 sentence "check" to ensure that students understand the difference between pero, sino, and sino que. There are two sets per page (to save paper). The key is included. Would make for a great warm-up activity, or a ticket out the door. Could even be used as a quick quiz!
The vocab used in the sentences is pretty general and non-specific, such that I think this would work with virtually any textbook.
