Reading

Task 1 Read the text carefully. Choose the correct answer.

Navajo National Monument in Tsege Canyon in Arizona is a place worth visiting. The Canyon was originally formed long ago by a river which used to flow (1) through/over the area. The ancient ancestors of the modern Native American people built villages high above the Canyon floor in "pockets" of empty space which occurred naturally in the Canyon walls. To reach the villages, people had to climb (2) up/into the sides of the Canyon walls. To protect people from the hot summer sun or the freezing winter winds, the houses didn't have doors-windows were used to enter (3) into/- houses. Some important buildings, where religious ceremonies took place, were built (4) under/into the ground. People went (5) down/into them by climbing (6) across/down wooden ladders. Today, you can go on a tour of the Canyon led by a trained Park Ranger and visit the ruins of the villages. You can walk or ride a horse across the Canyon through special paths.
