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. Several walls were being built as early as the 7th century BC; these, later joined together and made bigger, stronger, and unified are now collectively referred to as the Great Wall. The most famous wall was built between 220–206 BC by the first Emperor of China, Qin Shi Huang. The Great Wall stretches over 13,000 miles.
Can we infer that "The Great Wall of China was built in the 19th century"? Yes, no, or maybe?
