Suppose Lake Titicaca is a large, deep freshwater lake in the Andes mountains on the border of Bolivia and Peru. By volume of water and by surface area, it is the largest lake in South America. It is often called the "highest navigable lake" in the world, with a surface elevation of 3,812 meters (12,507 ft) above sea level.
Can we infer that "Lake Titicaca is the largest lake in the world by surface area."? Yes, no, or maybe?
