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. Construction began in the 7th century BC and continued for centuries, with some sections dating back to the Ming Dynasty (1368–1644).
Can we infer that "The Great Wall of China was built in a single year."? Yes, no, or maybe?
