From west to east, the great wall spans nearly 4,000 miles across china. it runs throughout five provinces and covers a range of landscapes that includes mountains, plateaus, and deserts. the wall is approximately twenty-five feet tall from bottom to top. its towers reach a height of about forty feet. rumors that the great wall is visible from outer space persisted for several decades, but astronauts orbiting earth on board the international space station have discredited this myth. they claim that you cannot see the wall with the naked eye. scientists can confirm that certain satellites are able to photograph portions of the wall, though.

a) the great wall is very large.
b) the great wall was built on a mountain.
