Both Ocala, Florida, and Lexington, Kentucky, are good places to raise racehorses, in part because of the limestone near the surface in both places. Calcium from the limestone helps make a horse's leg bones stronger and better able to withstand the pounding stress of running. Knowing that the Bluegrass Region around Lexington also sits on top of limestone, what other land features are also likely to be found there? A. sand dunes, lakes, and springs B. prairies, swamps, and marshes C. sinkholes, caves, and aquifers D. shallow rivers, flat land, and quartz sand
