Article: Ever tried taking smart drugs to perform better in exams? They certainly work. Before last summer's exam, a few of my mates, merely out of curiosity, took a considerable amount of Modafinil, a drug normally used for narcolepsy . Guess what? While I was feeling sleepy, bored by revision, my mates were more focused. Modafinil is a smart drug that gives a user a feeling of staying awake for hours. It also sharpens the mind, improves memory and helps problem-solving. But it does more than just keeping you awake. It disturbs your mental system, making you desperate to do what you are doing. You just don't want to do anything else but revise all the time non-stop. A recent study discovers that healthy people use smart drugs, like Modafinil, to get down to and complete tasks they have been putting off, because these tasks seem more enjoyable when taking these drugs. This might sound like what a stressed student desires. However, the pills have a range of side-effects. "At present no evidence shows that these drugs are safe in healthy people," as a medical expert puts it, "Ordering online, though easy, is a dangerous way to obtain drugs. You never know what you're actually purchasing. " In my experience, Modafinil changes people's behaviour too. Over those weeks my friends became different people--in turn aggressive, cold. Even eating became "a waste of time" and so did conversation. A BBC survey found that of those who had tried smart drugs before, 92% would do so again. My friends say they'd happily do so without considering the practice a form of cheating. I admit I was curious--but not enough to try it. Seeing the strange behaviour of other users, I feel a little bit upset and scary. Modafinil may promise to change your grades, but it might also change the way you act. Don't say you haven't been warned! Question: According to the author, his mates took Modafinil for the purpose of _ . Yes or no, is the answer "getting better exam results"?
No

Article: Petroleum, consisting of crude oil and natural gas, seems to originate from organic matter in marine sediment .Tiny organisms settle to the seafloor and gather in marine mud. The organic matter may partially break down, using up the dissolved oxygen in the sediment. As soon as the oxygen is gone, decay stops and the remaining organic matter is preserved. Continued sedimentation buries the organic matter and subjects it to higher temperatures and pressures, which change the organic matter to oil and gas. As muddy sediments are pressed together, the gas and small drops of oil may be squeezed out of the mud and may move into sandy layers nearby. Over millions of years, accumulations of gas and oil can collect in the sandy layers. Both oil and gas are less dense than water, so they generally tend to rise upward through rock and sediment. Oil pools are valuable underground accumulations of oil, and oil fields are regions underlain by one or more oil pools. When an oil pool or field is discovered, wells are drilled into the ground. When the well reaches a pool, oil usually rises up the well because of its density difference with water beneath it or because of the pressure of expanding gas trapped above it. Although this rise of oil is almost always carefully controlled today, strong natural flows of oil were common in the past. Gas pressure gradually dies out, and oil is pumped from the well. Water or steam may be pumped down neighboring wells to help push the oil out. As oil becomes increasingly difficult to find, the search for it is extended into more unfriendly environments. The development of the oil field on the North Slope of Alaska and the construction of the Alaska pipeline are examples of the great expense and difficulty involved in new oil discoveries. Offshore drilling platforms extend the search for oil to the ocean's continental shelves. More than one-quarter of the world's oil and almost one-fifth of the world's natural gas come from offshore, even though offshore drilling is six to seven times... Question: Which of the following is true about petroleum formation? Yes or no, is the answer "Petroleum formation appears to begin in marine sediments where organic matter exists."?
Yes

Q: Article: Turns out we aren't good at walking and talking at the same time, according to a study of pedestrians on their cell phones. Nearly one-third of pedestrians (29.8% ) were distracted by their mobile devices while crossing the street, say researchers of a study published online in the journal Injury Prevention. Just as drivers who text, talk on cell phones, or adjust MP3 players increase their risk of losing control of their vehicles, pedestrians distracted by their conversations or their devices also put themselves at higher risk of getting into an accident. During the summer of 2012, scientists in Seattle, Wash. , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years. They watched how pedestrians crossed the street @ whether they looked both ways or obeyed the crossroad signal @ and also recorded how long it took pedestrians to do so.Distractions included listening to music with headphones, using a cell phone or earpiece to talk on a cell phone, text messaging, and talking with another person. Overall, researchers found the most common distraction among pedestrians was listening to music (11.2%), followed by text messaging (7.3%), and using a handheld phone(6.2%). But the most absorbing distraction was texting. Compared to pedestrians who were not distracted, those who were texting took 1.87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk. While the study did not track injuries related to these trends, previous studies have linked such activities to a higher risk of being injured while crossing the street. Combined with the rise in the use of mobile devices, especially smart phones, the results raise concerns that multi-tasking while walking may be a rising concern for pedestrians. And that danger may only climb, as the number of wireless devices has already _ the population of the United States. Last year, roughly 1,152 people wound up... Question: According to the research, while crossing the street the most dangerous activity for apedestrian is _ . Yes or no, is the answer "texting messages"?
A: No

Article: A beggar followed a lady and asked her for some money. She refused, so he turned away sadly and said he must do what he had made up his mind to do. At this word, the lady was greatly frightened for she was afraid for his life. So she called him back and gave him a dollar.

The beggar replied, "Madame, I have been begging all day, but only you have taken pity on me. Without this dollar you gave to me, I should have had to go to work now. Question: The best headline for the story is _ . Yes or no, is the answer "Anything except Work"?
No
