Read the text and answer the questions according to it.
Many centuries ago, the Sahara was full of trees. As time passed, the land became dry and hot, and trees became rare. But one acacia tree in the Tenere region o f Niger survived longer than the rest. Caravans transporting goods across the vast desert used the tree of Tenere as a mark. This tree was so important for guiding across the sandy landscape that no one dared to cut off its branches for fire. It was the only tree for almost 400 kilometres around. In 1938, French military engineers dug a well near the tree. They discovered water more than 30 metres underground. Unfortunately, one of the military vehicles backed into the tree during the digging operation. The accident damaged one of the tree’s main branches. After World War II, lorries became the main form of transportation for caravans in the area, replacing camels. In 1973, the acacia tree was once again struck by another lorry. This time the tree could not sustain the force. A metal monument now stands where the tree once grew.
