instruction:
In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
question:
Passage: Speedy and his friend Miguel visit a ghost town in the desert, followed by Daffy. There, Speedy unveils what appears to be gold and a map to the location of the mine where more can be found. Daffy notices, and attempts to take the map; he is foiled by getting caught in the piano tape.
Daffy's next attempt involves setting up a phone with explosives. Speedy answers it when it rings, but quickly hands it to Daffy, saying he has a call; his plan backfires as he is blown up. Speedy teases him, "What's the matter, epa loco? You got the wrong number?" He takes off, Daffy in hot pursuit. Daffy finds him in a barrel, and throws a grenade in; however, he accidentally throws the pin, and not the actual grenade.
He then sticks his head through a hole in the fence, catching Speedy by the tail, but Miguel drops a horseshoe on him. Further antics ensue, including Daffy having a taxidermy bull head fall on him like a mask and Speedy (taking advantage of Daffy's appearance) acting as a matador, and Speedy hiding behind different-shaped bottles, only to get catsup in his eye on the last. Speedy and Miguel head to the mine, where Daffy repeatedly tries to throw dynamite in, to blow them up; it eventually blows up right next to him.
Daffy then demands that Speedy give up the cart, which he does. However, it is not gold, but cheese! Daffy then really does go crazy, bouncing away and laughing hysterically. When Miguel asks "Gee whiz, Speedy, what's the matter with the loco duck?", Speedy shrugs, "I dunno. I guess maybe he don't like cheese.".
answer:
Where does Speedy unveil a map?


question:
Passage: Rebuilding was rapid and performed on a grand scale. Rejecting calls to completely remake the street grid, San Franciscans opted for speed. Amadeo Giannini's Bank of Italy, later to become Bank of America, provided loans for many of those whose livelihoods had been devastated. The influential San Francisco Planning and Urban Research Association or SPUR was founded in 1910 to address the quality of housing after the earthquake. The earthquake hastened development of western neighborhoods that survived the fire, including Pacific Heights, where many of the city's wealthy rebuilt their homes. In turn, the destroyed mansions of Nob Hill became grand hotels. City Hall rose again in splendid Beaux Arts style, and the city celebrated its rebirth at the Panama-Pacific International Exposition in 1915.It was during this period San Francisco built some of its most important infrastructure. Civil Engineer Michael O'Shaughnessy was hired by San Francisco Mayor James Rolph as chief engineer for the city in September 1912 to supervise the construction of the Twin Peaks Reservoir, the Stockton Street Tunnel, the Twin Peaks Tunnel, the San Francisco Municipal Railway, the Auxiliary Water Supply System, and new sewers. San Francisco's streetcar system, of which the J, K, L, M, and N lines survive today, was pushed to completion by O'Shaughnessy between 1915 and 1927. It was the O'Shaughnessy Dam, Hetch Hetchy Reservoir, and Hetch Hetchy Aqueduct that would have the largest effect on San Francisco. An abundant water supply enabled San Francisco to develop into the city it has become today.
In ensuing years, the city solidified its standing as a financial capital; in the wake of the 1929 stock market crash, not a single San Francisco-based bank failed. Indeed, it was at the height of the Great Depression that San Francisco undertook two great civil engineering projects, simultaneously constructing the San Francisco–Oakland Bay Bridge and the Golden Gate Bridge, completing them in 1936 and 1937, respectively. It was in this period that the island of Alcatraz, a former military stockade, began its service as a federal maximum security prison, housing notorious inmates such as Al Capone, and Robert Franklin Stroud, the Birdman of Alcatraz. San Francisco later celebrated its regained grandeur with a World's fair, the Golden Gate International Exposition in 1939–40, creating Treasure Island in the middle of the bay to house it.
answer:
What is the name of the city that celebrated its rebirth at the Panama-Pacific International Exposition in 1915?


question:
Passage: Roosevelt regarded this offer of a joint project as sufficiently important to have the letter personally delivered by Frederick L. Hovde, the head of the NDRC mission in London, but Churchill did not respond until December. He assured Roosevelt of his willingness to collaborate, and informed him that Hovde had discussed the matter with Sir John Anderson and Lord Cherwell, as Frederick Lindemann was now known. The MAUD Committee had considered the issue of collaboration with the United States, and had concluded that while pilot isotope separation plants could be established in the United Kingdom, full-scale production facilities would have to be built in the United States. The British expressed concerns about the security of the American project. Ironically, it was the British project that had already been penetrated by atomic spies. John Cairncross had given the Soviet Union a copy of the MAUD Committee report. Although not conveyed to the Americans, the British had other concerns about what might happen after the war if the Americans embraced isolationism, as had occurred after the First World War, and Britain had to fight the Soviet Union alone. The opportunity for a joint project was therefore missed. British and American exchange of information continued but their programmes remained separate.
The Tube Alloys Directorate considered whether Britain could produce a bomb without American help. A gaseous diffusion plant to produce 1 kg of weapons-grade uranium per day was estimated to cost up to £3 million in research and development, and anything up to £50 million to build in wartime Britain. A nuclear reactor to produce 1 kg of plutonium per day would have to be built in Canada. It would take up to five years to build and cost £5 million. The project would also require facilities for producing the required heavy water for the reactor costing between £5 million and £10 million, and for producing uranium metal, which would cost another £1.5 million. The project would need overwhelming priority, as it was estimated to require 20,000 workers, many of them highly skilled, 500,000 tons of steel, and 500,000 kW of electricity. Disruption to other wartime projects would be inevitable, and it was unlikely to be ready in time to affect the outcome of the war in Europe. The unanimous response was that before embarking on this, another effort should be made to obtain American co-operation.By March 1943 Bush and Conant had decided that British help would benefit some areas of the Manhattan Project. In particular, it could benefit enough from assistance from Chadwick and one or two other British scientists to warrant the risk of revealing weapon design secrets. Bush, Conant and Groves wanted Chadwick and Peierls to discuss bomb design with Robert Oppenheimer, and the construction company Kellogg wanted British comments on the design of the gaseous diffusion plant it was building.
answer:

What is the name of the person that Churchill did not respond to until December?
