Question: Which mountain is Earth's highest peak, Ghent Kangri, or Mount Everest?

full_context: Document 1: Baltoro Kangri: Baltoro Kangri (Urdu: بلتورو کنگری‎ ; also known as the Golden Throne) is a mountain of the Karakoram mountain range in Gilgit-Baltistan, Pakistan. Baltoro Kangri is the 82nd highest mountain in the world with an elevation of 7312 m . It lies to the south of the Gasherbrums and east of Chogolisa Peak (7,665 m). The huge Baltoro Glacier (which is one of the largest glaciers outside polar regions) rises from the foot of Baltoro Kangri. In the north of Baltoro Kangri is the Abruzzi Glacier.
Document 2: Rimo Muztagh: The Rimo Muztagh is one of the most remote subranges of the Karakoram range. The southern part of Rimo Muztagh is in the Kashmir portion of far northwestern India, also claimed by Pakistan. The northern half, including the Rimo massif, is in the Siachen area (territory controlled by India). It is far from major towns, and close to the militarily sensitive Siachen Glacier, so it has seen little exploration or climbing activity compared to, for example, the nearby Baltoro Muztagh. The highest peak is Mamostong Kangri, 7,516 metres (24,659 feet).
Document 3: Gasherbrum: Gasherbrum (Urdu: گاشر برم‎ ) is a remote group of peaks located at the northeastern end of the Baltoro Glacier in the Karakoram range of the Himalaya on the border of the Chinese-administered Shaksgam Valley and the Gilgit-Baltistan territory of Pakistan. The massif contains three of the world's 8,000 metre peaks (if Broad Peak is included). Although the word "Gasherbrum" is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of Gasherbrum IV, it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain".
Document 4: Saltoro Kangri: Saltoro Kangri (Urdu: ‎ ) is the highest peak of the Saltoro Mountains, better known as the Saltoro Range, which is a part of the Karakoram. It is the 31st highest mountain in the world, but it is in a very remote location deep in the Karakoram. It is located on the Actual Ground Position Line between Indian controlled territory in the Siachen region and Pakistani-controlled territory west of the Saltoro Range.
Document 5: Mount Everest: Mount Everest, known in Nepali as Sagarmāthā and in Tibetan as Chomolungma, is Earth's highest mountain, located in the Mahalangur Himal sub-range of the Himalayas. The international border between China (Tibet Autonomous Region) and Nepal runs across its summit point.
Document 6: South Summit (Mount Everest): The South Summit of Mount Everest in the Himalayas is the second-highest peak on Earth, and is a subsidiary peak to the primary peak of Mount Everest. Although its elevation above sea level of 8749 m is higher than the second-highest mountain on Earth, K2 (whose summit is 8611 m above sea level), it is only considered a separate peak and not a separate mountain as its prominence is only 11 meters.
Document 7: Sherpi Kangri: Sherpi Kangri is a mountain peak in the Karakoram Range. It lies five km south of Ghent Kangri (7,380 m) and ten km northwest of Saltoro Kangri (7,742 m).
Document 8: Ghent Kangri: Ghent Kangri (or Mount Ghent, Ghaint I) is a high peak near the north end of the Saltoro Mountains, a subrange of the Karakoram range. It is located west of the Siachen Glacier in an area under Pakistan control, but very close to the Actual Ground Position Line with India.
Document 9: K12 (mountain): Surveyed as K12, this mountain is in the Saltoro Muztagh which is a subrange of the Karakoram range in the Siachen region, near Jammu and Kashmir. It lies near the Line of Control. Its name comes from its designation given during the original survey of the Karakoram range.
Document 10: Makalu: Makalu is the fifth highest mountain in the world at 8485 m . It is located in the Mahalangur Himalayas 19 km southeast of Mount Everest, on the border between Nepal and China. One of the eight-thousanders, Makalu is an isolated peak whose shape is a four-sided pyramid.
Document 11: Kangchenjunga: Kangchenjunga (Nepali: कञ्चनजङ्घा , "Kañcanajaṅghā"), also spelled Kanchenjunga, is the third highest mountain in the world, and lies partly in Nepal and partly in Sikkim, India. It rises with an elevation of 8586 m in a section of the Himalayas called "Kangchenjunga Himal" that is limited in the west by the Tamur River, in the north by the Lhonak Chu and Jongsang La, and in the east by the Teesta River.
Document 12: Gyachung Kang: Gyachung Kang (Nepali: ग्याचुङ्काङ , "Gyāchung Kāng"; ) is a mountain in the Mahalangur Himal section of the Himalaya, and is the highest peak between Cho Oyu (8,201 m) and Mount Everest (8,848 m). It lies on the border between Nepal and China. As the fifteenth-highest peak in the world, it is also the highest peak that is not eight thousand metres tall; hence it is far less well-known than the lowest of the eight-thousanders, which are only about 100 m (328 ft) higher. The peak's lack of significant prominence (700 m) also contributes to its relative obscurity.
Document 13: Sia Kangri: Sia Kangri (7,442 m, 24,370 ft) is a mountain in the Baltoro Muztagh in the Karakoram. Its summit is the tripoint of territory controlled by India, China and Pakistan where the Actual Ground Position Line between Indian and Pakistani forces meets Chinese-controlled territory. Territories on all sides are disputed. The land immediately to the southwest of the peak is claimed by both Pakistan and India and controlled by Pakistan. The land to the northeast is part of the Trans Karakoram Tract, controlled by China under a 1963 border agreement with Pakistan but claimed by India. The land to the southeast is claimed by Pakistan and India, but controlled by India, as a part of its Siachen glacier territory.
Document 14: Everest Base Camp: Everest Base Camp is either of two base camps on opposite sides of Mount Everest (It could also be any Everest base camp on given route, but this is less common since the two main routes became standardized). South Base Camp is in Nepal at an altitude of 5364 m ( ), and North Base Camp is in Tibet at 5150 m ( ). These camps are rudimentary campsites on Mount Everest that are used by mountain climbers during their ascent and descent. South Base Camp is used when climbing via the southeast ridge, while North Base Camp is used when climbing via the northeast ridge.
Document 15: Shishapangma: Shishapangma, also called Gosainthān, is the 14th highest mountain in the world at 8027 m above sea level. It was the last 8,000 metre peak to be climbed, due to its location entirely within Tibet and the restrictions on visits by foreign travelers to the region imposed by authorities of the Government of China and of the Tibet Autonomous Region.
