Suppose Mount Everest, also known in Nepal as Sagarmatha and in Tibet as Chomolungma, is Earth's highest mountain. It is located in the Mahalangur Himal sub-range of the Himalayas. The international border between Nepal and China runs across its summit point. Its elevation of 8,848.86 meters (29,031.7 ft) was most recently established in 2020 by China and Nepal.
Can we infer that "Mount Everest is the tallest mountain on Earth."? Yes, no, or maybe?
