I want to know the answer to the following question:
Pedro II was the Emperor of what Country?
All the background I'm provided with is that "Later Bell had the opportunity to demonstrate the invention personally to Sir William Thomson (later, Lord Kelvin), a renowned Scottish scientist, as well as to Queen Victoria, who had requested a private audience at Osborne House, her Isle of Wight home.". Is that enough to answer the question?
Answer: no
