premise: The European Organization for Nuclear Research (CERN) said on Monday that repairing the Large Hadron Collider (LHC) will cost up to €16.6 million or $21 million. The LHC, which is the world's largest and highest-energy particle accelerator, is located near the border of France and Switzerland and crosses the border four times. It has a diameter of 27 km (17 miles). It is designed to simulate the conditions shortly after the Big Bang, but it broke down on September 19 due to an electrical failure.
hypothesis: The final repair cost was $20 million.
reason: The statement is in the correct category because the value given in the excerpt is just an estimate of the cost before repairs began. There is no way to know the final cost because it is not given. The system may have had difficulty because it was not aware that the cost listed was not final.
