Task: Question Answering
Input (English): Passage: A speedy drafting process was required because Roosevelt, Churchill and their political and military advisors converged for the Quadrant Conference at the Citadelle of Quebec on 17 August, hosted by the Prime Minister of Canada, Mackenzie King. Most of the discussions were about the invasion of France. Although the Quebec Agreement was a bilateral one to which Canada was not a signatory, the British felt that Canada's contribution to Tube Alloys was significant enough that high-level representation was appropriate. King was therefore asked to nominate a Canadian member of the Combined Policy Committee, and he selected C. D. Howe, the Canadian Minister of Munitions and Supply. Stimson, Bush and Conant would be the American members, while Field Marshal Sir John Dill and Colonel J. J. Llewellin would be the British members.On 19 August Roosevelt and Churchill signed the Quebec Agreement, which was typed on four pages of Citadelle notepaper, and formally titled "Articles of Agreement governing collaboration between the authorities of the USA and UK in the matter of Tube Alloys". The United Kingdom and the United States agreed that "it is vital to our common safety in the present War to bring the Tube Alloys project to fruition at the earliest moment", and that this was best accomplished by pooling their resources. The Quebec Agreement stipulated that:
The US and UK would pool their resources to develop nuclear weapons with a free exchange of information;
Neither country would use them against the other;
Neither country would use them against other countries without consent;
Neither country would pass information about them to other countries without consent;. 
Question: What is the first name of the person who was asked to nominate a Canadian member of the Combined Policy Committee?
Output (English): Mackenzie.
