Suppose The Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials. Construction of the Great Wall began in the 7th century BC and continued for centuries, with various dynasties adding to the wall. It is estimated that the total length of the Great Wall is over 13,000 miles.
Can we infer that 'The Great Wall of China was built in a single year'? Yes, no, or maybe?
