Suppose the Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials. Originally built to protect the Chinese states and empires from invasions and raids, the wall stretches across northern China, spanning over 13,000 miles. It is one of the most recognizable and iconic landmarks in the world.
Can we infer that "The Great Wall of China was built to keep people out of China."?
