Hi this is sayor ajfar and id like to reply to your question.
It is not the eight wonder of the world. Its the second highest mountain?The great barrier reef in Australia is the eighth wonder of the world.

No i have studied in my book..it is the eighth wonder of the world...and my teacher want to know y is it so?

I think because of its natural beauty it is the eight wonder of the world or perhaps because nothing in the world has a landscape like this

This highway has been described as the eighth wonder of the world by hundreds of travelers and beyond any doubt, it is the marvel of modern engineering. The brave road builders of China and Pakistan took twenty years to complete this 1,300 km. long highway which has been stretched over the hills, gorges; valleys and rivers.
