Article: Earlier this month, the Obama Administration called for increased protection of the world's most southern continent, Antarctica.Scientists say climate change and human activity have increasingly led to the melting of massive pieces of Antarctic ice.The disappearance of ice will not only affect wildlife in the area such as seals and penguins.The melting will also cause oceans and seas around the world to rise. This represents a major threat, especially to coastal areas.For example, the ancient city of Venice, Italy has long been threatened by rising sea levels.The situation is made worse by the fact that its ancient buildings, built on a body of water called a lagoon , are slowly sinking.When the city was founded about 1,600 years ago, the level of the Adriatic Sea was almost two meters lower than it is today. Rising sea levels are not the only threat.The salty water is also destroying Venice's famous buildings and artworks.The Italian government is trying to fix the problem with the construction of a seven-billion-dollar system of moving flood barriers. Climate change is also leading to the melting of ice in other areas, such as Mount Kilimanjaro in northeastern Tanzania.It is the highest point in Africa, measuring almost 6,000 meters.The mountain supports five vegetation zones and many kinds of animals. The ice glaciers on the mountain are disappearing very quickly.This will have a bad effect on the mountain's ecosystems and on Tanzania's travel industry.Also, a valuable record of thousands of years of weather history will also be lost if the ice melts.Scientists study pieces of glacier to understand weather patterns from thousands of years ago. In the United States, the icy masses in Glacier National Park in Montana may soon completely disappear because of climate change.In 1850, there were an estimated 150 glaciers in the more than 400,000 hectare park. There are 26 glaciers remaining today.Scientists estimate that the glaciers will be gone by 2030.Warming... Question: The writer developed the passage mainly by _ .

People have always known that. At one time, some people even drank blood to make them strong! When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called "blood transfusion". The blood goes from the arm of the healthy person into the arm of the sick person. But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups--O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely. ks5u There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time. We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you. Question: Which of the following is true? Options: A: Doctors can give any kind of blood to the writer. B: The writer can give blood to B-group people. C: The writer has never had a blood transfusion. D: The writer has the same kind of blood as his father.
