Read the passage below carefully and answer the question that follows:

Located in Bauchi State in northeastern Nigeria, Yankari Game Reserve was originally created as a game reserve in 1956 and later opened to the public as Nigeria's premier national park in 1962. Spanning an area of approximately 2,244 square kilometres, the reserve is home to several natural warm water springs, the most famous of which is the Wikki Warm Spring. Unlike other springs whose water temperatures fluctuate with ambient weather, Wikki maintains a constant temperature of 31°C throughout the year due to geothermal heating deep underground. Additionally, the park features over 50 ancient Marshall Caves, which served as human settlements and hiding places during slave-hunting raids in the 19th century. Today, Yankari remains one of the few remaining natural habitats for West African elephants in Nigeria.
