Article: The work of railroad pioneers in America became the basis for a great surge of railroad building halfway though the nineteenth century that linked the nation together as never before. Railroads eventually became the nation's number one transportation system, and remained so until the construction of the interstate highway system halfway through the twentieth century. They were of great importance stimulating economic expansion,but their influence reached beyond the economy and was strong in American society at large. By 1804, English as American inventors had experimented with steam engines for moving land vehicles. In 1820,John Stevens ran a locomotive and cars around in a circular track on his New Jersey estate,which the public saw as amusing toy. And in 1825, after opening a short length of track, the Stockton to Darlington Railroad in England became the first line to carry general traffic. American businesspeople, especially those in the Atlanic coastal region who looked for better communication with the West, quickly became interested in the English experiment. The first company in America to begin actual operations was the Baltimore and Ohio,wich opened a thirteen-mile length of track in 1830. It used a team of horses to pull a trainof passenger carriages and freight wagons along the track. Steam locomotive power didn't come into regular service until two years later. However, for the first decade or more, there was not yet a true railroad system. Even the longest of the lines was ly short in the 1830's, and most of them served simply to connect water routes to each other, not to link one railroad to another. Even when two lines did connect, the tracks often differed in width, so cars from one line couldn't fit onto tracks of the next line. Schedules were unreliable and wrecks were frequent. Significantly, however, some important developments during the 1830's and 1840's included the introduction of heavier iron rails, more flexible and powerful locomotives, and passenger cars were redesigned to... Question: Which of the following can be inferred from the passage? Yes or no, is the answer "Steam locomotive power was first used in 1832"?
No

Article: Maybe you don't know the fact that the green forests we see from an airplane or from the highway can be false. Because centuries ago forests were twice as many as what they are today. A hike into many of those woods will tell different stories, too--of diseases and insects that are slowly killing trees, of some forests that are burned by fire, of logging that local people do more often. Deforestation and degradation of the world's forests mainly harm the basic ability of those ecosystems to function or provide services, such as fresh water, air, plants and animals, which benefit people everywhere and keep the balance of nature. Deforestation Forests today are a small part of what they once were. Nearly half of the world's forest cover is gone, and each year 40 million acres more are cut and replaced by agriculture and development. Over the next 45 years, wood use in the world is guessed to increase by 50 per cent over its present rate. Many of the forests that remain are severely destroyed, which harms the ability to protect birds or wild animals, and to supply natural resources to people. Deforestation also brings about between 20 per cent and 25 per cent of all air pollution causing global climate change. Degradation Forests continue to be degraded by some uses such as the gathering of wood for fuel, the arrival of pests and diseases that kill trees, the effects of climate change and poor management such as the fire, flood and so on. Question: Deforestation can do all the following harm EXCEPT _ . Yes or no, is the answer "stop agriculture developing"?
No

Q: Article: The legal age for drinking alcohol in the Unite States is twenty-one. Underage drinking is a crime but also a common part of college social life. This week in our Foreign Student Series, we look at alcohol rules at American colleges and universities. These rules differ from school to school, but many schools have been moving to strengthen their rules. The United States has more than 17,000,000 students in higher education. Each year, 1700 of them die from alcohol-related road crashes and other injuries. 600,000 more are injured while under the influence of alcohol. And almost 700,000 are attacked by another drunken. One behavior that college officials are trying to prevent is too much drink. Some researchers have found that students who think binge drinking is normal often think extremely how much other students really drink. A person can die of alcohol poisoning. At Oklahoma University, a nineteen-year-old student died from drinking heavily at a party in 2005. Now alcohol is banned from all sorority houses and university housing. Student organizations can serve alcohol at events but only on Friday and Saturday nights. Other new requirements include an alcohol education program that first-year students take online. The rules govern behavior on campus and off. With a first violation ,students pay seventy-five dollars and their parents are told. They must also take an alcohol education class. For a second "strike", they have to pay one hundred fifty dollars. A third strike means that they have to be suspended school for at least one semester. Since 2005,363 students have had a first strike. 30 have had a second strike-and only one hasn't allowed to go to school for one semester. The president at Oklahoma tells us the aim is not just to punish but to change the behavior and culture at the university. Question: If a student has a third strike, he or she should _ . Yes or no, is the answer "have to stop going to school for a time."?
A: No

Article: Tess still stood hesitating like a swimmer about to make his dive, hardly knowing whether to return or move forward, when a figure came out from the dark door of the tent. It was a tall young man, smoking. He had an almost black face, though red and smooth. His moustache was black with curled points, though he could not be more than twenty three or--four. There was an unusual force in his face, and in his daring rolling eyes. "Well, my beauty, what can I do for you?" said he, coming forward. And seeing that she was quite at a loss, "Never mind me. I am Mr. d'Urberville. Have you come to see me or my mother?" This differed greatly from what Tess had expected. She had dreamed of an aged and dignified face. She tried to keep calm and answered-- "I came to see your mother, sir." "I am afraid you cannot see her--she is ill in bed," replied the representative of the house; for this was Mr. Alee, the only son of the noble family. "What is the business you wish to see her about?" "It isn't business--it is--I can hardly say what!" "Pleasure?" "Oh no. Why, sir, if I tell you, it will seem..." Tess's sense of a certain ridicule was now so strong that, despite her general discomfort at being here, her rosy lips curved towards a smile, much to the attraction of the young man. "It is so foolish", she stammered . "I fear I can't tell you!" "Never mind; I like foolish things. Try again, my dear," said he kindly. "Mother asked me to come," Tess continued; "and, indeed, I was in the mind to do so myself. But I did not think it would be like this. I came, sir, to tell you that we are of the same family as you." "Ho! Poor relations?" "Yes." "Stokes?" "No; d'Urbervilles." "Ay, ay; I mean d'Urbervilles." "Our names are worn away to Durbeyfield; but we have several proofs that we are d'Urbervilles. The local scholars hold the view that we are, and...and we have an old seal and a silver spoon marked with the same castle as yours. So mother said we ought to make ourselves known to you, as we've lost our horse by a bad... Question: Why does Tess pay the visit to the d'Urbervilles? Yes or no, is the answer "To make known their relationship and seek help."?
