Answer 1

Answer:

The Himalaya has witnessed numerous intriguing and interesting events ranging from the rich exchange of art, science and culture between civilisations of Europe and Asia to threatening wars and disputes that intimidated India. The rugged terrain and the harsh climatic conditions did not discourage travellers such as Fa Hein and Hiuen Tsang from entering India through the many formidable ‘saddle points’ or cols (passes) carved through the snowbound Himalayan mountain range.
