Input: Read this: GE has a history of some of its activities giving rise to large-scale air and water pollution. Based on year 2000 data, researchers at the Political Economy Research Institute listed the corporation as the fourth-largest corporate producer of air pollution in the United States, with more than 4.4 million pounds per year (2,000 tons) of toxic chemicals released into the air. GE has also been implicated in the creation of toxic waste. According to EPA documents, only the United States Government, Honeywell, and Chevron Corporation are responsible for producing more Superfund toxic waste sites.
Question: Which organization identified GE as the fourth largest corporate producer of air pollution in the US?

Output: Political Economy Research Institute

Input: Read this: Although there is some evidence of earlier inhabitation in the region of Utrecht, dating back to the Stone Age (app. 2200 BCE) and settling in the Bronze Age (app. 1800800 BCE), the founding date of the city is usually related to the construction of a Roman fortification (castellum), probably built in around 50 CE. A series of such fortresses was built after the Roman emperor Claudius decided the empire should not expand north. To consolidate the border the limes Germanicus defense line was constructed along the main branch of the river Rhine, which at that time flowed through a more northern bed compared to today (what is now the Kromme Rijn). These fortresses were designed to house a cohort of about 500 Roman soldiers. Near the fort settlements would grow housing artisans, traders and soldiers' wives and children.
Question: Who settled near the fort

Output: Near the fort settlements would grow housing artisans, traders and soldiers' wives and children

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: When uranium isotope is formed from the decay of neptunium-237?

Output: uranium-233

Input: Read this: The rapid development of religions in Zhejiang has driven the local committee of ethnic and religious affairs to enact measures to rationalise them in 2014, variously named "Three Rectifications and One Demolition" operations or "Special Treatment Work on Illegally Constructed Sites of Religious and Folk Religion Activities" according to the locality. These regulations have led to cases of demolition of churches and folk religion temples, or the removal of crosses from churches' roofs and spires. An exemplary case was that of the Sanjiang Church.
Question: What was not an exemplary case of all this?

Output:
unanswerable
