I'm taking a test and have to guess the right answer to the question after the article. Article: One rainy evening I went to fill up at the gas station. A pre-teen boy approached my car and asked me for money to help him and his mother stay in their hotel for an additional week. He stated that if they did not come up with $25 they would be _ that same evening. Having worked in social services before and having doubt about this, I asked why his mother hadn't applied for social services for assistance. The boy said that they needed to remain in their hotel for one more week until his grandmother, who lived out of town, could take them in. I gave the boy what I had -- $5. He thanked me and continued to wander the parking lot asking for help. I got my gas and drove away. Some weeks ago, a boy asked me for money and I told him I didn't have any though I did. Yet, I thought about it for a while and went looking for the boy to give him a dollar. But it seemed that he had disappeared into thin air. "This time," I thought, "I'll do it differently." I went to my bank and got an additional $20, then I returned to the gas station. The boy was still there. I observed him shyly approaching strangers who walked past him without notice. I pulled up and waved at the boy to come over. I handed him the $20 bill. He reached through my car window and gave me a huge hug. His hug told me all I needed to know -- that finally this kid could get out of the rain, the cold and the darkening skies and go inside where it was warm. Question: When the boy received the $20 bill, he was _ . Options: A: thankful B: astonished C: doubtful D: ashamed

I'm taking a test and have to guess the right answer to the question after the article. Article: The Entropia Universe The Entropia Universe is a virtual world on the Internet, which seems very like our real life.It is set in a distant future and based on a planet called Calypso.Entropia was the brainchild of a group of Swedish computer lovers who decided to see if they could create a three dimensional virtual world that could be placed on the Internet.They did manage after they received the financial backing they needed. The game can be played for free, but nearly all in-game activities require personal resources that you have available to use.Although there are various activities to keep you busy on Calypso, what most people do first is to find themselves a profession, such as hunting the fierce animals on Calypso, mining the precious minerals and making tools.Then they can think about buying their virtual house or paying a visit to a virtual nightclub or doing any of the other activities that make life bearable. Entropia has its very own economy and its own currency, the PED (Project Entropia Dollars).Players move real world money into PED which they then use to pay for their life on Calypso.However, the virtual things inside Entropia do have a real value in the outside world, and careful business deals mean that players can actually make real money there.PED can be changed into dollars any time at a rate of 10PED to 1US$. What's so impressive about The Entropia Universe is the number of players; currently more than 600,000 representing over 220 countries from planet Earth.A number of players insist that it's a good way to make money.However, the reality of Entropia's economic system is that most people end up paying more than they earn and it's not uncommon to find players who are paying up to $200 a month into their PED account.This might not be the most economical way of spending one's free time.However, some people say that for them the fact that they can escape the realities of the earthbound life and become a different person with a completely different life for a few hours every week is... Question: According to the author, playing on The Entropia Universe _ . Options: A: may be very annoying B: can be quite expensive C: is a cheap way to kill time D: is a good way to earn money

I'm taking a test and have to guess the right answer to the question after the article. Article: If you want to walk in the footsteps of some of the world's greatest figures, then go to Oxford. Many of Oxford's 38 colleges are open to the public year-round. Here are a few of the colleges worth visiting and some famous people who have studied there. Christ Church College Long before it became known as a location for the Harry Potter films, Christ Church was the college where Albert Einstein, author Charles Dodgson who wrote Alice in Wonderland, and 13 British prime ministers studied. In this large and popular college, you can see the paintings in the 16th-century Great Hall. Magdalen College Many consider Magdalen to be one of the most beautiful Oxford's colleges. This is where author Oscar Wilde read his classics course. You can enjoy the medieval church with its 15th-century tower. Opposite the college is the beautiful Botanic Garden founded in 1621. Merton College Founded in 1264, Merton has the oldest medieval library in use. J. R. R. Tolkien is said to have spent many hours here writing The Lord of the Rings. One of the college's treasures is an astrolabe ,thought to have belonged to Chaucer. The college has the most amazing collection of medieval colored glass in Oxford. Bodleian Library The Bodleian Library, the main research library of the University of Oxford, is the largest university library in the UK. It is one of the oldest libraries in Europe, and in Britain is second in size only to the British Library. It holds more than 9 million printed items on 189 km of shelving and seats up to 2,500 readers. The users of the library here include five kings, 40 Nobel Prize winners, 25 British prime minister and countless famous writers. Question: Which of the following can travelers see in Magdalen College? Options: A: A 15 th-century tower. B: A seven-ton tower bell. C: England's smallest cathedral. D: British oldest botanic garden.

I'm taking a test and have to guess the right answer to the question after the article. Article: Pollutants coming from automobile operation have begun to cause many environmental problems. It has been calculated, for example, that 70% of the carbon monoxide , 45% of the nitrogen oxides , and 34% of the hydrocarbon pollution in the United States can be traced directly to automobile exhausts . In addition, rubber, motor oil and other materials accumulate on roadways and are washed into streams, with effects nearly as serious as those of untreated waste water. In an effort to improve the situation, the U.S. government has made regulations on the use of the constituents of automobile exhaust gas that are known to cause air pollution. These constituents fall roughly into three types: hydrocarbons that pass through the engine unburned; carbon monoxide, also a product of incomplete burning; and nitrogen oxides which are formed when nitrogen and oxygen are in contact at high temperatures. Besides their own poisonous character, hydrocarbons and nitrogen oxides react in the presence of sunlight to form harmful smog. Carbon monoxide and hydrocarbons are rather easily controlled by the use of higher burning temperatures in engines. Unfortunately, the conditions that produce minimum emission of hydrocarbons tend to raise emission of nitrogen oxides. In a way this difficulty is solved by adding recycled exhaust gas to the fuel mixture, thus avoiding the oversupply of oxygen that favors formation of nitrogen oxides. California, which has the most strict air-pollution laws in the United States, requires further special compounding of gas to control emissions, and several states have ordered that alcohol be mixed with gas, as this will reduce emissions of the carbon monoxide by 35 per cent and the hydrocarbons by 15 per cent. Question: According to the text, alcohol is added to gas in order to _ . Options: A: increase awareness of environment protection B: control air pollution C: increase the fuel efficiency D: replace gas gradually
