I want to know the answer to the following question:
What was the world's first artificial nuclear reactor?
All the background I'm provided with is that "The X-10 Graphite Reactor at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X-10 Pile, was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile) and was the first reactor designed and built for continuous operation.". Is that enough to answer the question?
Answer: yes
