Read the passage and choose the best answer to each of the following questions.

The glaciers of the Himalayas and the Andes could disappear in this century. As a result, the millions of people in India, Bolivia and Peru who now depend on melting water from mountain glaciers could find themselves in a critical situation. The ice sheet of Greenland is also melting more quickly than the scientists predicted. Greenland’s largest outlet glacier, the Jakobshavn Ibra glacier, is moving toward the sea twice as fast as it was in 1995. One cause could be meltwater that runs down to the bottom of the glacier and gets between the ice and the rock below. This water makes it easier for the glacier to slide along to the ocean. Many ice researchers believe that Greenland’s melting, if it continues, will add at least three feet to global sea levels by the year 2100. If the ice sheet of Antarctica, now largely unaffected, begins to melt, the next few conturies could see a six-foot rise in sea levels, forcing tens of millions of people out of their homes.
