Question: What is the elevation of the land formation near where Khaplang was born? Passage:Khaplang was born in Waktham in April 1940, a village east of Myanmar's Pangsau Pass as the youngest of ten children. Born into Hemi Naga tribe that lived predominantly in Myanmar, his early childhood was shaped by the opening up of isolated Naga communities by the World War II. During the War, the Western Allies built the long Stilwell Road connecting Ledo in India's Assam to China's Kunming to carry supplies against the Japanese Army, that passed through Waktham. This was said to have "sowed the seeds of insurgency in Khaplang." Khaplang claimed that he first attended a school in Margherita, a town in Assam before joining Baptist Mission School in Myitkyina in Myanmar's Kachin State in 1959, and in 1961 to another missionary school in Kalay before he eventually dropped out.
