Suppose The Pyramids of Giza is an archaeological site on the Giza Plateau, on the outskirts of Cairo, Egypt. This complex of ancient monuments includes the three pyramid complexes known as the Great Pyramids, the massive sculpture known as the Great Sphinx, several cemeteries, a workers' village, and an industrial complex. It is one of the original Seven Wonders of the Ancient World.
Can we infer that "The Pyramids of Giza were built in the 20th century."? Yes, no, or maybe?
