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 to protect against invasions. The walls were built during different dynasties in China and combined measure over 13,000 miles.
Can we infer that "the Great Wall of China was built during a single dynasty"? Yes, no, or maybe?
