user: I'm taking a test and have to guess the right answer to the question after the article. Article: Masses of floating ice are so large that they dwarfs your ship, making you question whether your ship still can be spotted among such floating mountains. They are so improbable looking that you simply look in wonder. It seems that nothing that large could be natural-- and then it strikes you that something so large could only be natural.   Now, people realize that as climate change is raising global temperatures, more icebergs are being born. Antarctica creates far more of them than Greenland, the source of bergs in Arctic waters. Antarctica's are also much larger, sometimes reaching the size of small countries. Recent data show the average atmospheric temperature has increased about 4.5degF in the western Antarctic Peninsula since the 1940s, making the region, among the fastest warming on earth. This jump has been shown in the recent breaking of major ice shelves along the Antarctic Peninsula. As a result, thousands of new icebergs have broken off, from ice shelves into the Southern Ocean at an accelerated rate. Even as more icebergs are being created, scientists are learning that these beauties are far from inactive masses of ice. In fact, they strikingly alter their environments biologically, chemically, and physically, making them islands of life in the open sea. Observers at sea had long remarked that they attract seals, and seabirds, and divers had noticed that fish are more numerous near them than in the surrounding sea. Now scientists are learning just what the attraction is all about. Depending on their size, location, and the season, icebergs can be nurturers or destroyers. During their existence--typically years from breaking off from an Antarctic or Greenlandic glacier to their gradual melting as they float into lower altitudes, they support animals on, around, even inside their splendid ice castle. They fertilize the ocean with nutrients, increasing sea creature production. Grounded bergs can shelter areas of the seafloor, protecting bottom-living creatures from free-floating icebergs. However,... Question: From the passage we can conclude that icebergs can   _  . Options: A: preserve ocean life B: carry ocean nutrients away C: create a warm polar environment D: keep sea animals away from polar seas

I'm taking a test and have to guess the right answer to the question after the article. Article: April 23 marks the 400th anniversary of William Shakespeare's death. Organizations in Britain have planned numerous events to honor him. In Stratford-upon-Avon, his birthplace, the tourism organization has a great number of free events, including performances of Shakespeare's plays, and a dazzling fireworks display. And the BBC is broadcasting a live show from Stratfore-upon-Avon, celebrating Shakespeare's widespread influence on the world. In England's capital, the London Shakespeare Centre and King's College London are holding a series of public performances, exhibitions and activities. It isn't just England that honors the anniversary of the death of this extraordinary writer. In Washington, D. C., the Folger Shakespeare Library, which houses the world's largest collection of documents relating to William Shakespeare, is displaying a series of exhibitions. Shakespeare is probably the most famous author who ever lived an is considered a genius by most. He wrote around 37 plays and 154 sonnets , and his work has been translated into over one hundred languages! He penned beautiful metaphors , serious dramas and amusing tales. Shakespeare also invented many new terms and phrases. If someone's behavior suggested they were not being honest and should not be trusted, Shakespeare called their actions suspicious. If someone was being silly and perhaps looking like a fool, Shakespeare found their actions laughable. And Shakespeare called people who offered their opinions on the quality of something critics. Today, for instance, food critics and film critics give audiences their opinions of food and film. The familiar phrase "break the ice" comes from Shakespeare's play The Taming of the Shrew. The "ice is broken" when a difficult conversation or meeting is calmed by some basic introduction, such as a simple game. More common words coined by Shakespeare include road, gossip, lonely, bump and hurry. Four hundred years after his death, Shakespeare surely lives on, in everyday speech, as the most famous writer of all time! Question: According to the next, a simply game to make a difficult conversation easy is called   _  . Options: A: an ice-breaker B: a suspicious man C: a critic D: a laughable man

I'm taking a test and have to guess the right answer to the question after the article. Article: prefix = st1 /Gland, Switzerland - Rivers on every continent are drying out, threatening severe water shortages, according to a new WWF report. The report, World's Top Rivers at Risk, released ahead of World Water Day (22 March), lists the top ten rivers that are fast dying as a result of climate change, pollution and dams. "All the rivers in the report symbolize the current freshwater crisis, which we have been signalling for years," says WWF Global Freshwater Programme Director Jamie Pittock. "Poor planning and inadequate protection of natural areas mean we can no longer assume that water will flow forever. Like the climate change crisis, which now has the attention of business and government, we want leaders to take notice of the emergency facing freshwater now not later."  Five of the ten rivers listed in the report are in Asia alone. They are the Yangtze, Mekong, Salween, Ganges and Indus. Europe's Danube, the America'sLa Plataand Rio Grande/Rio Bravo, Africa's Nile-Lake Victoria andAustralia's Murray-Darling also make the list. Dams along the Danube River -- one of the longest flowing rivers in Europe -- have already destroyed 80 per cent of the river basin's wetlands and floodplains. Even without warmer temperatures threatening to melt Himalayan glaciers, the IndusRiverfaces scarcity due to over-extraction for agriculture. Fish populations, the main source of protein and overall life support systems for hundreds of thousands of communities worldwide, are also being threatened. The report calls on governments to better protect river flows and water allocations in order to safeguard habitats and people's livelihoods. "Conservation of rivers and wetlands must be seen as part and parcel of national security, health and economic success," Pittock adds. "Emphasis must be given to exploring ways of using water for crops and products that do not use more water than necessary." In addition, cooperative agreements for managing shared resources, such as the UN Watercourses Convention, must be ratified and given... Question: According to the passage, which of the following is not the cause of severe water shortage? Options: A: Globe warming B: Less rainfall C: Pollution D: Poor planning
