Comprehension: (76-80) Read the following information carefully and answer the given questions. Cave, also called cavern, natural opening in the earth large enough for human exploration. Such a cavity is formed in many types of rock and by many processes. The largest and most common caves are those formed by chemical reaction between circulating groundwater and bedrock composed of limestone or dolomite. These caves, called solution caves, typically constitute a component of what is known as karst terrain. Named after the Karst region of the western Balkan Peninsula extending from Slovenia to Montenegro, karst terrain in general is characterized by a rough and jumbled landscape of bare bedrock ledges, deranged surface drainage, and sinkholes, as well as caves. It should be noted, however, that there is considerable variation among karst areas. Some may have dramatic surface landforms but few caves do not. By contrast, others may have extensive cave development with little surface expression; for example, the Guadalupe Mountains of New Mexico, the site of Carlsbad Caverns and various other caves, have very few surface karst features. Karst landscapes are formed by the removal of bedrock (composed in most cases of limestone, dolomite, gypsum, or salt, but in some cases of such normally insoluble rocks as quartzite and granite) in solution through underground routes rather than through surface weathering and surface streams. As a result, much karst drainage is internal. Rainfall flows into closed depressions and down their drains. Further dissolution in the subsurface forms continuous conduits that serve as integrated drains for the rapid movement of underground water. The outlets for the water-carrying conduits often are springs of majestic size. Caves are fragments of such conduit systems, and some of them provide access to active streams. These caves may be completely water-filled; others are dry passages left behind by streams that cut to lower levels. Surface streams flowing from areas underlain by insoluble rock often sink when they reach the border of a karst region. These sinking streams form tributaries of the underground drainage system. Not all caves are part of karst landscapes. A substantial number of relatively small caves, called volcanic caves, are formed in lava and by the mechanical movement of bedrock. Other caves are formed in glaciers by the melting of ice. Still others are reated by the erosive action of water and wind or from the debris of erosive processes; these are sea caves, eolian caves, rock shelters, and talus caves. Which of the following caves is/are not one of the examples of extensive cave development with little surface expression? I. The Guadalupe Mountains of New Mexico II. The site of Carlsbad Caverns
