Suppose Mount Everest is the highest mountain in the world, located in the Himalayas on the border between Nepal and China. The first recorded successful ascent of Mount Everest was in 1953 by Sir Edmund Hillary of New Zealand and Sherpa Tenzing Norgay. Since then, thousands of people have attempted to reach the summit, with varying degrees of success and tragedy.
Can we infer that "Sir Edmund Hillary was the first person to climb Mount Everest alone?"
