I want to know the answer to the following question:
UCL Partners is the largest type of what facility in Europe?
All the background I'm provided with is that "London is home to five major medical schools – Barts and The London School of Medicine and Dentistry (part of Queen Mary), King's College London School of Medicine (the largest medical school in Europe), Imperial College School of Medicine, UCL Medical School and St George's, University of London – and has a large number of affiliated teaching hospitals.". Is that enough to answer the question?
