Question: Which mountain is found in Pakistan, either Trivor or Muztagh Ata?
Context: Muztagh Tower (also: Mustagh Tower; "Muztagh": ice tower), is a mountain in the Baltoro Muztagh, part of the Karakoram range in Baltistan on the border of the Gilgit–Baltistan region of Pakistan and the Xinjiang Uyghur Autonomous Region of China.  It stands between the basins of the Baltoro and Sarpo Laggo glaciers. Passu Sar (Urdu: ‎ ; or Passu Sar, Passu I) is a mountain peak in the Batura Muztagh, a sub-range of the Karakoram mountain range, located in the Gilgit District of Gilgit-Baltistan, Pakistan, west of the Hunza Valley.  It is the high point of the Passu massif, which also includes Passu Diar (or "Passu East", "Pasu II").  The peak lies on the main ridge of the Batura Muztagh, about 7 km (4 mi) east of Batura Sar. Hispar Muztagh is a sub-range of the Karakoram mountain range.  It is located in the Gojal region of Gilgit-Baltistan, Pakistan, north of Hispar Glacier, south of Shimshal Valley, and east of the Hunza Valley.  It is the second highest sub-range of the Karakoram, the highest being the Baltoro Muztagh.  The highest mountain in the range is Distaghil Sar (7,885m/25,869 ft). 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. Muztagh Ata, or Muztagata (Uyghur: مۇز تاغ ئاتا, Музтаң Ата, literally "ice-mountain-father"; ), is the second highest (7509 metres) of the mountains which form the northern edge of the Tibetan Plateau (not the second highest of the mountains of the Tibetan Plateau).  It is sometimes regarded as being part of the Kunlun Shan, although physically it is more closely connected to the Pamirs.  It is also one of the relatively easier 7,000 m peaks in the world to climb, due to its gentle western slope and the comparatively drier weather of Xinjiang, though a thorough acclimatization period and a very strong physical condition are crucial for success. Lenin Peak (Kyrgyz: Ленин Чокусу , "Lenin Çoqusu", لەنىن چوقۇسۇ; Russian: Пик Ленина , "Pik Lenina"; Tajik: қуллаи Ленин, "qulla‘i Lenin/qullaji Lenin" , renamed қуллаи Абӯалӣ ибни Сино (qulla‘i Abûalî ibni Sino) in July 2006), or Ibn Sina (Avicenna) Peak, rises to 7,134 metres (23,406 ft) in Gorno-Badakhshan (GBAO) on the border of Tajikistan and Kyrgyzstan, and is the second-highest point of both countries.  It is considered one of the easiest 7000 m peaks in the world to climb and it has by far the most ascents of any 7000 m or higher peak on Earth, with every year seeing hundreds of climbers make their way to the summit.  Lenin Peak is the highest mountain in the Trans-Alay Range of Central Asia, and in the Pamir Mountains in Tajikistan it is exceeded only by Ismoil Somoni Peak (7,495 m).  It was thought to be the highest point in the Pamirs in Tajikistan until 1933, when Ismoil Somoni Peak (known as "Stalin Peak" at the time) was climbed and found to be more than 300 metres higher.  Two mountains in the Pamirs in China, Kongur Tagh (7,649 m) and Muztagh Ata (7,546 m), are higher than the Tajik summits. Bolor-Tagh is an old name for the longitudinal range in eastern Pamir Mountains (ancient Mount Imeon) extending from Kunlun Mountains in the south to the east extremity of the Trans-Alay Range in the north.  Highest peaks Kongur Tagh (7649 m) and Muztagh Ata.  Bolor-Tagh lies entirely in the Xinjiang province of western China.  Marco Polo visited the area in 1271 during his travel to China, describing it under the name of ‘Bolor’. Trivor (Urdu: ترِووُر‎ ) is one of the high peaks of the Hispar Muztagh, a subrange of the Karakoram range in the Gilgit-Baltistan of Pakistan. Tomas Kenneth Olsson (March 18, 1976 – May 16, 2006) was a Swedish adventurer and extreme skier.  He was born in Kristinehamn but grew up in Borås.  He took an engineering degree at Linköping University in 2001, after which he moved to Chamonix in France to focus on skiing.  He specialized in skiing down some of the world's highest and steepest mountains.  He has gone from the top of Aconcagua in Argentina (6960 m), Lenin Peak in Kyrgyzstan (7134 m), Muztagh Ata (7546 m) and Kuksay Peak (7134 m) in China and Cho Oyu in Tibet (8201 m). Chakragil (or Chagragil, Chakar Aghil, Kingata Tagh [or Kingata Tagh II, see below]) is a major mountain in Xinjiang, China.  It is located about 100 km southwest of Kashgar, about 60 km due north of Muztagh Ata, and 37 km northwest of Kongur Tagh.  It is in the subrange known as the Kingata Shan, generally included in the "Eastern Pamirs" as it (and the neighboring Kongur Shan range) are separated by the major Yarkand River valley from the extreme northwest end of the Kunlun Mountains, near the Pamir Mountains.  The Gez River flows just south of the mountain.
