I'm taking a test and have to guess the right answer to the question after the article. Article: There is very simple way of measuring the height of a water-tower, which we cannot measure by climbing. Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is standing and measure a distance of, say, 25 feet from it. Then we take a stick, and stand it in the ground at the spot we have just marked. Let us suppose the stick we are using is 4 feet in height. We now walk farther away from the water -tower in the same straight line as when we measured off the distance of 25 feet. We go from the water-tower until we come to point E, where with our head on the ground, we see the top of the stick and the top of the water-tower in the same height line---that is, the top of the stick just covers the highest part of the water-tower. Every schoolboy can work out the height of the water-tower now. Suppose that the line CE is five feet. We know that the stick is 4 feet high and the distance BE is 30 feet. Thus, 5 is to 4 as 30 is to AB. Question: It is clear from this that the problem can be settled by _ . Options: A: a child B: the boy who has little schooling C: everyone D: a girl at middle school

I'm taking a test and have to guess the right answer to the question after the article. Article: Charles Darwin (1809 - 1882) was a great naturalist, famous for his theory of evolution . One day two boys decided to play a trick on the great man. They took the body of a centipede , the head of a beetle , the leg of a grasshopper , and the wings of a butterfly, and glued them together. Putting the strange creature into a box carefully, they took it to Darwin. "Please, sir," said one of the two boys, "can you tell us what sort of a bug this is?" The naturalist looked at the bug and then at the boys. "Did it hum ?" he asked. "Oh, yes. It did!" "In that case," declared Darwin, "I would say it's a humbug !" Question: What did the two boys do in order to play a trick on Darwin? Options: A: They caught a strange creature and took it to Darwin. B: They put several insects together and took them to Darwin. C: They made a strange bug by putting together different parts of different insects and took it to Darwin. D: They put a strange animal into a box and took it to Darwin.

I'm taking a test and have to guess the right answer to the question after the article. Article: It's impossible to determine how many people would have lost their lives without the contribution of African-American inventor Dr Charles Drew. Charles Drew was born on June 3, 1904, in Washington, DC. His early interest was in education, but he was also an outstanding athlete. While in college, he was awarded as the man who contributed the most to sports during his four years in school. Drew's sister Elsie suffered from tuberculosis and died in 1920. Her death influenced his decision to study medicine. After becoming a doctor and working as a college instructor, Drew went to Columbia University, where he earned his Doctor of Medical Science degree. During this time he became involved in research on blood and blood transfusions. At Columbia, he wrote a paper on "banked blood", in which he described a technique he developed for the long-term preservation of blood plasma. Before his discovery, blood could not be stored for more than two days because of the rapid breakdown of red blood cells. Drew had discovered that by separating the plasma from the whole blood and then refrigerating them separately, they could be combined a week later for a blood transfusion. Drew became the first African American to receive a PhD in medical science. After World War II broke out, Drew was called upon to put his techniques into practice. He was named a project director for the American Red Cross but soon quit his post after the government issued an order that blood taken from white donors should be separated from that of black donors. On April 1, 1950, after he attended the annual free clinic at the John A. Andrew Memorial Hospital, he and other three physicians decided to drive back home. As he was tired from spending the night before in the operating room, he lost control of his car. Drew was badly injured and was taken to Alamance General Hospital in Burlington, North Carolina. He was pronounced dead half an hour after he first received medical attention. Drew's funeral was held on April 5, 1950, at the Nineteenth Street...
