Suppose the Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials. It was built along the northern borders of China to protect against invasions and raids. The wall stretches over 13,171 miles from the Bohai Sea in the east to the Gobi Desert in the west.
Can we infer that "The Great Wall of China was built solely as a tourist attraction"? Yes, no, or maybe?
