Suppose Mount Everest is the world's highest mountain, with a peak at 8,848 meters above sea level. It is located in the Himalayas on the border between Nepal and China. The first successful ascent to the summit was made by Sir Edmund Hillary and Tenzing Norgay in 1953.
Can we infer that "Mount Everest is the second tallest mountain in the world."? Yes, no, or maybe?
