Input: Read this: Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally.
Question: What isotope of uranium is formed when 239U experiences spontaneous fission?

Output: unanswerable

Input: Read this: As a result of these initiatives northeastern Florida prospered economically in a way it never did under Spanish rule. Furthermore, the British governors were directed to call general assemblies as soon as possible in order to make laws for the Floridas and in the meantime they were, with the advice of councils, to establish courts. This would be the first introduction of much of the English-derived legal system which Florida still has today including trial by jury, habeas corpus and county-based government. Neither East Florida nor West Florida would send any representatives to Philadelphia to draft the Declaration of Independence. Florida would remain a Loyalist stronghold for the duration of the American Revolution.
Question: What did representatives draft in Florida?

Output: unanswerable

Input: Read this: A pub /pb/, or public house is, despite its name, a private house, but is called a public house because it is licensed to sell alcohol to the general public. It is a drinking establishment in Britain, Ireland, New Zealand, Australia, Canada, Denmark and New England. In many places, especially in villages, a pub can be the focal point of the community. The writings of Samuel Pepys describe the pub as the heart of England.
Question: Other than the United States, where in North America are pubs located?

Output: Canada

Input: Read this: The FBI often works in conjunction with other Federal agencies, including the U.S. Coast Guard (USCG) and U.S. Customs and Border Protection (CBP) in seaport and airport security, and the National Transportation Safety Board in investigating airplane crashes and other critical incidents. Immigration and Customs Enforcement Homeland Security Investigations (ICE-HSI) has nearly the same amount of investigative man power as the FBI, and investigates the largest range of crimes. In the wake of the September 11 attacks, then-Attorney General Ashcroft assigned the FBI as the designated lead organization in terrorism investigations after the creation of the U.S. Department of Homeland Security. ICE-HSI and the FBI are both integral members of the Joint Terrorism Task Force.
Question: When does the FBI work with the US Coast Guard and US Customs and Board Protection?

Output:
seaport and airport security
