Input: Consider Input: Passage: Britain's declaration of war against Nazi Germany in September 1939 included the Crown colonies and India but did not automatically commit the Dominions of Australia, Canada, New Zealand, Newfoundland and South Africa. All soon declared war on Germany, but Ireland chose to remain legally neutral throughout the war.After the Fall of France in June 1940, Britain and the empire stood alone against Germany, until the German invasion of Greece on 7 April 1941. British Prime Minister Winston Churchill successfully lobbied President Franklin D. Roosevelt for military aid from the United States, but Roosevelt was not yet ready to ask Congress to commit the country to war. In August 1941, Churchill and Roosevelt met and signed the Atlantic Charter, which included the statement that "the rights of all peoples to choose the form of government under which they live" should be respected. This wording was ambiguous as to whether it referred to European countries invaded by Germany and Italy, or the peoples colonised by European nations, and would later be interpreted differently by the British, Americans, and nationalist movements.In December 1941, Japan launched, in quick succession, attacks on British Malaya, the United States naval base at Pearl Harbor, and Hong Kong. Churchill's reaction to the entry of the United States into the war was that Britain was now assured of victory and the future of the empire was safe, but the manner in which British forces were rapidly defeated in the Far East irreversibly harmed Britain's standing and prestige as an imperial power. Most damaging of all was the Fall of Singapore, which had previously been hailed as an impregnable fortress and the eastern equivalent of Gibraltar. The realisation that Britain could not defend its entire empire pushed Australia and New Zealand, which now appeared threatened by Japanese forces, into closer ties with the United States. This resulted in the 1951 ANZUS Pact between Australia, New Zealand and the United States of America.
Question: What location was the city that was seen as impregnable fortress considered to be the eastern equivalent of?

Output: Gibraltar.

Input: Consider Input: Passage: In 1938 Egypt, a team of archaeologists discover the tomb of pharaoh Ahkmenrah, including a young Cecil Fredericks, finding the magical Tablet of Ahkmenrah. The locals warn the group that removing the tablet will end its magic. In present-day New York City, Larry Daley remains the night guard of the American Museum of Natural History. He, Theodore Roosevelt, Sacagawea, Attila the Hun, Jedediah, Octavius, Rexy the Tyrannosaurus rex skeleton and Dexter the capuchin monkey help re-open the Hayden Planetarium. A new wax Neanderthal resembling Larry named Laaa is introduced, identifying Larry as his father. Ahkmenrah shows Larry that the tablet is corroding, which later causes the exhibits to act erratically, causing mayhem at the planetarium's reopening. Afterwards, Larry catches his son Nick, who plans on taking a gap year to sort out his life, throwing a house party.
Larry reunites with Cecil, now in retirement, who realizes the end of the tablet's magic will cause the exhibits to become lifeless. Cecil explains that Ahkmenrah's parents, Merenkahre and Shepseheret, may be able to restore the tablet's power but that they are located in the British Museum. Larry convinces the museum's curator, Dr. McPhee, to let him ship Ahkmenrah to London to restore the tablet, convinced that McPhee knows its secrets. Larry and Nick travel to the British Museum, bypassing the night guard Tilly. To Larry's surprise, Roosevelt, Sacagawea, Attila, Jed, Octavius, Dexter and Laaa have come as well, and Laaa is left to stand guard while the others search the museum, the tablet bringing its own exhibits to life.
Question: What is the last name of the person who is helped by the museum exhibits to re-open the planetarium?

Output: Daley.
