I. Read the passage and answer the questions.
Boasting picturesque landscapes from the north to the south, Viet
Nam is home to the world’s largest cave - Son Doong. Son Doong Cave is
located in Phong Nha - Ke Bang National Park, Quang Binh province. The
cave contains a 5-km tunnel which can reach a height of 250 metres and a
width of 200 metres. The main cave is large enough to house a 40-floor
skyscraper. It’s quite surprising that the first to discover this cave was a
local farmer in 1990, but it took almost two more decades for Son Doong
to be rediscovered. The team of locals and British explorers found the
whole impressive ecosystem with a set of caves, tunnels, beaches, lakes
and rivers in 2009.
Now Son Doong is one of the world’s greatest natural wonders, along
with the Grand Canyon, Victoria Falls, Mount Everest, etc. The first guided
tours to the safe part of the cave started in 2013. Adventurous travellers
can book a trip to explore the magnificent ecosystem and sleep in unique
campsites at this mysterious cave.
