Context and question: Because of his stammer, Albert dreaded public speaking. After his closing speech at the British Empire Exhibition at Wembley on 31 October 1925, one which was an ordeal for both him and his listeners, he began to see Lionel Logue, an Australian-born speech therapist. The Duke and Logue practised breathing exercises, and the Duchess rehearsed with him patiently. Subsequently, he was able to speak with less hesitation. With his delivery improved, the Duke opened the new Parliament House in Canberra, Australia, during a tour of the empire in 1927. His journey by sea to Australia, New Zealand and Fiji took him via Jamaica, where Albert played doubles tennis partnered with a black man, which was unusual at the time and taken locally as a display of equality between races.

Answer: Lionel Logue

Problem: Namibia:

South West Africa became known as Namibia by the UN when the General Assembly changed the territory's name by Resolution 2372 (XXII) of 12 June 1968.
