Article: Oil is so important that it is sometimes called "black gold". Almost half of our energy comes from oil. We use it to run our cars and factories and to heat our homes, offices and schools. Many everyday things are made from oil. Your shirt may have oil in the material. The soap you wash your hands with might also be made from oil. Your favorite plastic toy is made from oil. Oil is hard to find, because it is trapped deep under the earth. Once the only way people knew there was oil someplace if it leaked out of the ground. Today, however, we have many ways of finding oil. One tool measures the pull of gravity. Places where gravity is weaker are more likely to have oil. Another tool is sound waves . Sound waves travel through different kinds of rocks at different speeds. We can use them to find the rocks that have oil in them. We need a lot of oil, and we are using up the oil wells we know about. Soon we must find new ways of looking for this "black gold". Question: Which of the following does the passage lead you to believe? Yes or no, is the answer "Many things are made from oil."?
(Answer)
No

Article: Many years ago, when I was working as a volunteer at a hospital, I got to know a little girl named Lisa. The poor little girl had a very serious disease and was dying. The doctor had done his best but no medicine really worked. The only chance to save her seemed to be a blood transfusion  from her five-year-old brother. The little boy had the same disease before and had developed the antibodies  to fight the illness. The doctor talked to the little boy about what they planned to do, and asked him if he would be willing to give his blood to his sister. I saw him hesitate  for a moment. He took a deep breath and said, "Yes, I'll do it if it can save Lisa." As the transfusion was going on, the little boy lay quietly in bed next to his sister. He looked at her and smiled all the time. When everything was done and the colour returned to his sister's face, his smile disappeared and he looked a little afraid. He looked up at the doctor and asked, " Will I start to die now?" He was too young to understand the doctor. He thought he would have to give all his blood to his sister, but he agreed. Question: The writer still remember the story many years later   _  . Yes or no, is the answer "because of what the boy did for his sister"?
(Answer)
Yes
