Input: Article: In early 1942, the governments of smaller powers began to push for an inter-governmental Asia-Pacific war council, based in Washington, D.C.. A council was established in London, with a subsidiary body in Washington. However, the smaller powers continued to push for an American-based body. The Pacific War Council was formed in Washington, on 1 April 1942, with President Franklin D. Roosevelt, his key advisor Harry Hopkins, and representatives from Britain, China, Australia, the Netherlands, New Zealand, and Canada. Representatives from India and the Philippines were later added. The council never had any direct operational control, and any decisions it made were referred to the U.S.-UK Combined Chiefs of Staff, which was also in Washington. Allied resistance, at first symbolic, gradually began to stiffen. Australian and Dutch forces led civilians in a prolonged guerilla campaign in Portuguese Timor.

Now answer this question: When was the Pacific War Council formed in Washingto D.C.?

Output: 1 April 1942

Input: Article: Several governments maintain permanent manned research stations on the continent. The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times. Many of the stations are staffed year-round, the winter-over personnel typically arriving from their home countries for a one-year assignment. An Orthodox churchTrinity Church, opened in 2004 at the Russian Bellingshausen Stationis manned year-round by one or two priests, who are similarly rotated every year.

Now answer this question: What is the span of population density per million square kilometers of researchers in Antarctica?

Output: between 70 and 350
