Suppose Mount Everest is the highest mountain in the world, with a peak that reaches an elevation of 8,848 meters above sea level. It is located in the Himalayas on the border between Nepal and China. The first successful summit of Mount Everest was achieved by Sir Edmund Hillary and Tenzing Norgay in 1953.
Can we infer that "Mount Everest has never been successfully climbed."? Yes, no, or maybe?
