Suppose The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials, generally built along an east-to-west line across the historical northern borders of China. The wall was originally conceived by Emperor Qin Shi Huang in the 3rd century BC as a means of protection against invasions from nomadic tribes.
Can we infer that "The Great Wall of China was built for aesthetic purposes only."? Yes, no, or maybe?
