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. The most famous wall starts from Shanhaiguan in the east and ends at Jiayuguan in the west, totaling around 13,171 miles in length.
Can we infer that "The Great Wall of China is entirely made of brick"? Yes, no, or maybe?
