Question: Which mountain is higher Gangkhar Puensum or Jongsong Peak ?

full_context: Document 1: 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".

Document 2: 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 3: 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.
