Question: Which mountain is taller, Istor-o-Nal or Siguang Ri?

full_context: Document 1: 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.
Document 2: Gasherbrum I: Gasherbrum I (Urdu: ‎ ; ), surveyed as K5 and also known as Hidden Peak, is the 11th highest mountain in the world at 8080 m above sea level. It is located on the Pakistani–Chinese border in Gilgit–Baltistan region of Pakistan and Xinjiang region of China. Gasherbrum I is part of the Gasherbrum massif, located in the Karakoram region of the Himalaya. Gasherbrum is often claimed to mean "Shining Wall", presumably a reference to the highly visible face of the neighboring peak Gasherbrum IV; but in fact it comes from "rgasha" (beautiful) + "brum" (mountain) in Balti, hence it actually means "beautiful mountain."
Document 3: Langtang Ri: Langtang Ri is a mountain in the Langtang Himal of the Himalayas. At an elevation of 7205 m it is the 106th highest mountain in the world. Located on the border between the Bagmati Zone of Nepal and Tibet, China, it is part of a group of high peaks that include Shishapangma (8,013 m) and Porong Ri (7,292 m).
Document 4: Siguang Ri: Siguang Ri is a mountain in the Mahalangur Himalayas of Tibet, China. At an elevation of 7308 m it is the 83rd highest peak on Earth. It is located approximately 6 kilometers NNE of Cho Oyu, the world's 6th highest mountain.
Document 5: K6 (mountain): Surveyed as K6 (Urdu: کے 6‎ ), but also known as Baltistan Peak. This is a notable peak of the Masherbrum Mountains, a subrange of the Karakoram mountain range in Gilgit Baltistan region of Pakistan. Despite being much lower than its sister mountains, the Eight-thousanders and high 7000m peaks such as Masherbrum, it has huge, steep faces, and great relief above the nearby valleys.
Document 6: 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 7: Tirich Mir: Tirich Mir (Khowar/Urdu: ‎ ) (alternatively Terich Mir, Terichmir and Turch Mir) is the highest mountain of the Hindu Kush range, and the highest mountain in the world outside of the Himalayas-Karakoram range, located in Chitral District of Pakistan. The mountain was first climbed in 1950 by a Norwegian expedition consisting of Arne Næss, P. Kvernberg, H. Berg, and Tony Streather. Tirich Mir overlooks Chitral town, and can be easily seen from the main bazaar.
Document 8: Momhil Sar: Momhil Sar, or Mumhail Sar as pronounced in Wakhi is at 7343 m above sea level, is the 64th highest mountain peak in the world. Mumhail Sar in Wakhi means the mountain that overlooks or is above Grandmother's cattle pen or paddock. It is situated in the Hispar Muztagh subrange of the Karakoram range, a few kilometres to the north-west of its parent peak Trivor.
Document 9: Istor-o-Nal: Istor-o-Nal or इस्तोर-ओ-नल is the third highest mountain in the Hindu Kush, in the Chitral District of the North-West Frontier Province of Pakistan. It is the 68th highest independent peak in the world. It crowns a massif with eleven peaks of elevation more than 7000 m . The peak is located a few kilometres northeast of Tirich Mir (the highest mountain in the Hindu Kush), across the Tirich Glacier. Because Istor-o-Nal is behind the higher peak of Tirich Mir from many viewpoints, it is not easily visible and therefore not well known.
Document 10: Rush Peak: Rush Peak is a mountain in the Karakoram mountain range of Central Asia. It is located in the Nagar District of Gilgit-Baltistan, Pakistan. While not a high peak by local standards, it is noteworthy as a remote trekking destination. It can be reached via Nagar Valley and Hoper Village. The peak can be accessed via Hoper Glacier (Bualtar Glacier) and Barpu Glacier. The peak is relatively easy to climb in the summer months and ascents have been made by amateur climbers without proper mountaineering gear. In winter, access to the mountain is made difficult by heavy snows. The top of the peak provides stunning views of Miar Peak (6,824 m), Miar Glacier and Phuparash Peak (6,574 m). On a clear day, one can look east and see some of the world's highest mountains, including K2 and Broad Peak. At the mountain's base lies one of the world's highest alpine lakes, Rush Lake (4,694m).
Document 11: Noshaq: Noshaq (also called Nowshak or Nōshākh; Urdu/Persian/Pashto: نوشاخ‎ ) is the highest peak in Afghanistan and the second highest peak in the Hindu Kush Range (after Tirich Mir) at 7492 m . It lies on the border between Badakhshan Province in Afghanistan and Chitral District, Khyber Pakhtunkhwa, Pakistan, and is the world's westernmost 7,000 meter massif.
Document 12: 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 13: Siniolchu: Siniolchu is one of the tallest mountains of the Indian state of Sikkim. The 6888 m mountain is considered to be particularly aesthetically attractive, having been described by Douglas Freshfield as "the most superb triumph of mountain architecture and the most beautiful snow mountain in the world". It is situated near the green lake adjacent to Kangchenjunga, the highest peak in the state and third highest in the world.
Document 14: Jongsong Peak: Jongsong Peak is a mountain in the "Janak" section of the Himalayas. At 7462 m it is the 57th highest peak in the world, although it is dominated by 3rd highest, Kangchenjunga, 20 km to the south. Jongsong's summit is on tri-junction of India, Nepal and China.
Document 15: 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.
