Suppose Niagara Falls is a collective name for three waterfalls that straddle the international border between the Canadian province of Ontario and the US state of New York. They are located approximately 17 miles northwest of Buffalo. The American Falls, Bridal Veil Falls, and Horseshoe Falls make up Niagara Falls.
Can we infer that "Niagara Falls is a man-made attraction."? Yes, no, or maybe?
