I want to know the answer to the following question:
How many schools offer polytechnics?
All the background I'm provided with is that "The polytechnics of Thuringia are based in Erfurt (4,500 students), Jena (5,000 students), Nordhausen (2,500 students) and Schmalkalden (3,000 students).". Is that enough to answer the question?
Answer: yes
