Input: Consider Input: Question: In what year was the royal house's name change? Passage:The programme explores the lives of King George V and Queen Mary, and their attempts at modernising the British Monarchy in response to the massive social changes during and following World War I. The first episode recalls how, fearing anti-German sentiment, the royal house name was changed by King George from the House of Saxe-Coburg and Gotha to the House of Windsor. The series also examines the personal lives of the couple, delving into their relationships with their children, and with each other. The marriage between George and Mary was an arranged marriage, occurring only because Prince Albert Victor, George's brother and Mary's original fiancé, died from influenza. George V is presented in the series as a disciplinarian, who strictly punished his children, but was known to be much more loving to his granddaughter, Queen Elizabeth II.

Input: Consider Input: Question: In what country is The Poole Harbour? Passage:The Poole Harbour area has been inhabited for at least 2,500 years. During the Iron Age, Celtic people known as the Durotriges lived in Dorset, particularly around Wareham, five miles (8 km) to the west. In the 3rd century BC, these Celtic people moved from hilltop settlements, such as Maiden Castle and Badbury Rings on the chalk downs to the north, to the lower vales and heathland around the River Frome and Poole Harbour. This marshy area may have lent its name to the Durotriges, which means "water dwellers". The Durotriges engaged in cross-channel trading at Poole with the Veneti, a seafaring tribe from Brittany. The earliest significant archaeological find in the harbour is the Poole Logboat, a boat made from a single oak tree and dating to 295 BC. During that time, the harbour was shallower than it is today and any settlement would now be under water.
