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 construction of these walls began as early as the 7th century BC, with the well-known sections built during the Ming Dynasty (1368–1644).
Can we infer that "The Great Wall of China was built in less than a year."? Yes, no, or maybe?
