I want to know the answer to the following question:
On what date was the first self-sustained nuclear chain reaction created artificially?
All the background I'm provided with is that "On 2 December 1942, as part of the Manhattan Project, another team led by Enrico Fermi was able to initiate the first artificial self-sustained nuclear chain reaction, Chicago Pile-1.". Is that enough to answer the question?
Answer: yes
