Suppose Mount Everest, located in the Himalayas, is the highest mountain in the world, with a peak at 8,848 meters. It was first successfully climbed by Sir Edmund Hillary and Tenzing Norgay in 1953. The mountain is a popular destination for experienced climbers looking to conquer the highest peak on Earth.
Can we infer that "Mount Everest has never been climbed before 1953."?
