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 of the wall started as early as the 7th century BC and continued for centuries. The most well-known sections of the wall were built by the Ming Dynasty (1368-1644).
Can we infer that "The Great Wall of China was built in a very short period of time."? Yes, no, or maybe?
