Suppose Mount Everest is Earth's highest mountain above sea level, located in the Mahalangur Himal sub-range of the Himalayas. The China–Nepal border runs across its summit point. The current official height of 8,848.86 metres (29,031.7 ft), recognized by China and Nepal, was established by a 2020 Chinese survey.
Can we infer that "Mount Everest is the tallest mountain in the United States."? Yes, no, or maybe?
