Article: Though the facts that too many people on earth and a too rapid increase in the number added each year are not in argument, we always begin the discussion of "population as global issue" with what most persons mean like this. It was quite right to compare demographic growth to "a long, thin powder fuse that bums steadily and hesitatingly until it finally reaches the charge and explodes". To understand the current situation, which is characterized by rapid increases in population, it is necessary to understand the history of population trends. Rapid growth is a comparatively recent phenomenon. Looking back at the 8,000 years of demographic history, we find that populations have been virtually stable or growing very slightly for most of human history. For most of our ancestors, life was hard, often nasty, and very short. There was high fertility in most places, but this was usually balanced by high mortality. For most of human history, it was seldom the case that one in ten persons would live past forty, while infancy and childhood were especially risky periods. Often, societies were in clear danger of extinction because death rates could exceed their birthrates. Thus, the population problem throughout most of history was how to prevent extinction of the human race. This pattern is important to notice. Not only does it put the current problems of demographic growth into a historical perspective, but it suggests that the cause of rapid increase in population in recent years is not a sudden enthusiasm for more children, but an improvement in the conditions that traditionally have caused high mortality. Demographic history can be divided into two major periods: a time of long, slow growth which extended from about 8000 B.C. till approximately 1650 A.D. In the first period of some 9,600 years, the population increased from some 8 million to 500 million in 1650. Between 1650 and 1975, the population has increased from 500 million to more than 4 billion. And the population reached 6.2 billion throughout the world by the year 2000, One way to appreciate this dramatic difference in such abstract numbers is to reduce the time frame to something that is more manageable. Between 8000 B.C. and 1650, an average of only 50,000 persons was being added annually to the world's population, At present, this number is added every six hours. The increase is about 800000,000 persons annually.
Question: Which of the following demographic growth patterns is most similar to the long thin powder fuse?
Options: (A) A slow growth for a long time and then a period of rapid, dramatic increase. (B) Too many people on earth and a few rapid increases in the number added each year. (C) A virtually stable or slightly decreasing period and then a sudden explosion of population. (D) A long period when death rates exceed birthrates and then a short period with higher fertility and lower mortality.

Article: It was the last time Susan Butcher ran the Iditarod Trail Sled Dog Race in 1992. An hour into the race, Susan and her sled dog team sped down a hill and crashed into a fallen tree. Although hurt, Susan continued the difficult race. The Iditarod Race started in 1925 when a doctor in Nome, Alaska was desperately in need of medicine to stop the spread of a deadly disease. Only a hospital had what he needed, but it was 700 mile-away! In January, it was too dangerous to send a boat and too stormy for his tiny airplane. The only hope was to use several sled dog teams following a trail, called the Iditarod Trail. They passed the medicine from one sled team to another. Wind and snow did not stop the men and their dogs. The medicine was delivered in record time. The race follows the route of the famous medicine run. Over 1,000 miles long, it is considered the toughest race in the world. Susan Butcher was born in Cambridge, Massachusetts. In her teens Susan was given a Siberian husky dog and became very interested in huskies as sled dogs. After reading about the Iditarod Race, Susan moved to Alaska. She got several jobs to earn money to buy herself a sled and a team of huskies. After years of hard work and training, Susan achieved her dream of racing on the Iditarod Trail. In 1978, at the age of 24, Susan entered the race for the first time and became the first woman to finish in the top 20. In 1982 she came in second. In 1984 she was leading her team across a frozen waterway when they fell into the water. Her lead dog managed to pull Susan and the other dogs out of danger. Remarkably, she came in second. In her fourth race, in 1985,a starving moose attacked her dogs, killing two and injuring eleven. Susan had to leave the race. In 1986 Susan joined the race again. This time, she won. She won again in 1987. In 1988 she became the first person ever to win three Iditarod races in a row. Unbelievably, Susan won for the fourth time in 1990.

Article: When people talk about Golden Age in Leadville, Horace Austin Warner Tabor and his second wife, Elizabeth McCourt must be included. Their story is becoming one of the legends of the Old West. H.A.W.Tabor was a school teacher in Vermont. With his first wife and two children he left Vermont in 1855 to settle in Kansas. Perhaps he was attracted by rumors of fortunes to be made in Colorado mines. A few years later he moved west to the small Colorado mining camp known as California Gulch, which he later renamed Leadville when he became its leading citizen. "Great deposits of lead are sure to be found here."he said. As it turned out, it was silver, not lead, that was to make Leadville's fortune and wealth. Tabor knew little about mining himself, so he opened a general store selling everything from boots to salt, flour, and tobacco. He often "grubstook" miners, in other words, to supply them with food and supplies, or"grub", while they looked for more. In return he would get a share in the mine if one was discovered. He did this for several years,but nobody he helped ever found anything of value. Finally one day in the year 1878, so the story goes, two miners came in and asked for "grub".Tabor had decided to quit supplying it because he had lost too much money that way. They were persistent, however, and Tabor was too busy to argue with them, " Oh help yourself. One more time won't make any difference," He said and went on selling shoes and hats to other customers. The two miners took $17 worth of supplies, in return for which they gave Tabor a one-third interest in their findings. They picked a barren place on the mountain side and began to dig. After nine days they struck a rich amount of silver. Tabor bought the shares of the other two men, and so the mine belonged to him alone. This mine, known as the "Pittsburgh Mine,"made $300 000 for Tabor in return for his $17 investment. Later Tabor bought the Matchless Mine on another barren hillside just outside the town for $117 000. This turned out to be even more successful than the Pittsburgh, earning $35 000 worth of silver per day at one time. Leadville grew. Tabor became its first mayor.
Question: According to the passage, why was Tabor able to achieve great success in Leadville?
Options: (A) His wise decisions helped him achieve goals. (B) He knew miners there were poor. (C) He succeeded quite by accident. (D) His second wife helped him a lot.
