Suppose The Great Wall of China was built over several centuries by various Chinese dynasties starting from the 7th century BC. It spans over 13,000 miles and is a UNESCO World Heritage Site. The wall was built to protect China from invasions and raids by nomadic groups from the north such as the Mongols and Xiongnu.
Can we infer that "The Great Wall of China was built in a single year."? Yes, no, or maybe?
