I'm taking a test and have to guess the right answer to the question after the article. Article: Our factories and homes burn coal and oil. Every year we have forest fires somewhere. Many scientists believe that the weather is changing. The earth will perhaps be warmed by about 7degC at the South Pole and the North Pole. The ice will be melt . The sea level will rise by about 7 meters. As a result, water will cover cities like London, Tokyo and New York. Some ports and towns along the coasts will disappear under water. Some other scientists think that the dust, smoke and pollution from coal, wood and oil fires will block out the ultraviolet rays . Then the earth will become colder and great sheets of ice will cover Europe and North America. When chemicals in the air mix with rain, we have acid rain. Acid rain can bring us great harm. It destroys forests and kills life in lakes and rivers. People are beginning to see how serious the problem is. They find it important to work with nature instead of against it. They are trying to save the earth in many different ways. But one of the most important things to do is to make people understand that saving the earth is saving ourselves. ,. Question: Ice at the poles willif the earth gets warmer. Options: A: become thicker by seven meters B: cover cities like London and Tokyo C: raise the sea level by 7 degrees D: become water and make the sea rise
A:
D
