Suppose The Great Wall of China is a series of walls and fortifications made of brick, stone, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China. The wall was originally built by several Chinese states during the Warring States period and later connected and fortified by the first emperor of China, Qin Shi Huang, to protect against invasions from nomadic tribes.
Can we infer that "The Great Wall of China was built in the 18th century."? Yes, no, or maybe?
