Suppose the Great Wall of China is a series of fortifications made of stone, brick, tamped earth, wood, and other materials. It was built to protect the northern borders of the Chinese Empire from invasions and raids by various nomadic groups. Construction of the wall started as early as the 7th century BC and continued through the Ming Dynasty in the 17th century AD.
Can we infer that the Great Wall of China was only built during a specific time period in history?
