Suppose The Great Wall of China is a historic fortification that stretches over 13,000 miles (21,196 kilometers) across northern China. It was built over several centuries and served as a defense against invasions from nomadic tribes. The Great Wall is a UNESCO World Heritage Site and a popular tourist destination, attracting millions of visitors each year.
Can we infer that "The Great Wall of China was built in a single year."? Yes, no, or maybe?
