Retreаt frоm the Cоаst [H] With the threаt оf sea-level rise everywhere, cities around the world have turned to the Netherlands for guidance - a country that has faced and overcome the problem of rising seas. One Dutch firm, Arcadis, has prepared a design for a storm-surge barrier to protect New York City. The same company helped design a barrier 3.2 kilometers long that protected New Orleans from Hurricane Isaac's four-meter storm surge in 2012. "Isaac was a tremendous victory for New Orleans," said Piet Dircke, an Arcadis executive. "All the barriers were closed; all the levees held; all the pumps worked. You didn't hear about it because nothing happened." [I] New Orleans may be safe for a few decades, but the long-term prospects for it and other low-lying cities look dire. Even if we begin reducing our emissions of heat-trapping gases tomorrow, oceans will likely rise as Earth slowly adjusts to the amount already in the atmosphere. Among the most vulnerable cities is Miami. "I cannot envision southeastern Florida having many people at the end of this century," says Hal Wanless, chair of the University of Miami's Department of Geological Science. "We think Miami has always been here and will always be here. How do you get people to realize that Miami - or London - will not always be there?" [J] Unless we change course dramatically, our carbon emissions will drastically change the geography of many shorelines by the next century, if not sooner, and large numbers of people will have to abandon coastal areas in Florida and other parts of the world. "From the Bahamas to Bangladesh and a major amount of Florida, we'll have to move, and we may have to move at the same time," says Wanless. Columbia University geophysicist Klaus Jacob sees most of Manhattan's population fleeing to higher ground and the island becoming a kind of Venice, subject to periodic flooding, perhaps with canals and yellow water cabs. At different times in different countries, engineering solutions will no longer be enough. Then the retreat from the coast will begin. QUESTION: Which of the following sentences from paragraph I gives the author's main argument?

Rising SeаsAs the plаnet wаrms, the sea rises, and cоastlines flооd, how will we face the danger of rising seas? Storm of the Century [A] By the time Hurricane Sandy veered toward the northeast coast of the United States on October 29, 2012, it had mauled 1 several countries in the Caribbean and left dozens dead. Faced with the largest storm the Atlantic had ever produced, New York and other cities ordered mandatory evacuations of low-lying areas, but not everyone complied. Those who chose to ride out Sandy got a preview of the future, in which a warmer world will lead to rising seas. [B] Brandon d'Leo, a sculptor and surfer, rented a second-floor apartment across the street from the beach on New York City's Rockaway Peninsula. At about 3:30 in the afternoon, he went outside. Waves were crashing against the nine-kilometer-long boardwalk. A short time later, d'Leo and a neighbor were watching the sea through the glass door of his living room when his neighbor saw something alarming. "I think the boardwalk just moved," she said. Within minutes, another surge of water lifted the boardwalk again, and it began to break apart. [C] Three large sections of the boardwalk smashed against two pine trees in front of d'Leo's apartment. The street had become a river 1.2 meters deep; cars began to float. After the storm, d'Leo said, "I have six surfboards in my apartment, and I was thinking, if anything comes through that wall, I'll try to get everyone on those boards and try to get up the block." [D] After a difficult night's sleep, d'Leo went outside and saw that the water had retreated, thigh-deep pools still filled parts of some streets. "Everything was covered with sand," he said. "It looked like another planet." 1 If someone is mauled (e.g., by a wild animal), they are attacked fiercely and aggressively. QUESTION:Who does the word "those" in the last sentence of paragraph A refer to?  Be specific.
