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 to protect the Chinese states and empires against the raids and invasions of nomadic groups. Several walls were being built by various Chinese states during the Spring and Autumn (771–476 BC) and Warring States periods (475–221 BC).
Can we infer that "The Great Wall of China was built to protect against aerial attacks."? Yes, no, or maybe?
