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 built to protect the Chinese states from invasions and raids by nomadic groups. It is one of the most famous historical landmarks in the world.
Can we infer that "The Great Wall of China was built in a single day"? Yes, no, or maybe?
