SSC Selection Post 2022 PYQ — Question 23

Read the given passage and answer the questions that follow.

The Blue Mountains National Park in Australia gets its name from the natural blue haze. This haze is created by the vast eucalyptus forests present in this famous world heritage area. Here, tiny droplets of oil get released from the tree and mix with water vapour and sunlight. These produce a distinctive colour as the name suggests – Blue Mountains. One of the main highlights of this area is Jenolan caves, which have limestone chasms. There is a sky ride present across the valley. A breathtaking view of the mountains can be seen from these caves. These caves are the world’s oldest caves. These caves are considered to be one of the world’s most inspiring wonders.
