Q: Article: A powerful earthquake struck the northeastern coast of Japan at two forty-six p.m. local time on March eleventh.2011. Japan's Meteorological Agency released its first tsunami warnings just three minutes later. The country has one of the best earthquake early warning systems in the world. There are more than four thousand Seismic Intensity Meters in place throughout Japan to measure earthquake activity. These meters provide information within two minutes of an earthquake happening. Information about the strength and the center of the earthquake can be learned within three minutes. There are also concrete sea walls around much of the Japanese coastline. But these measures proved no match for the powerful earthquake and tsunami. Costas Synolakis ,a tsunami expert at the University of Southern California in Los Angeles said,"Japan is one of those most well-prepared countries on earth in terms of tsunami warning. They had a warning. I think what went wrong is that they had not expected the size of this event." He says there are two reasons for this. Japan has not had any event anywhere near as big as this one in the last one hundred fifty years. And scientists had not expected such a large earthquake happening off the coast of Japan. The nine point zero magnitude earthquake was the fourth most powerful earthquake ever recorded worldwide. It was also the worst earthquake ever to hit Japan. The tsunami waves that followed were reported to have reached as high as thirteen meters in some areas. Costas Synolakis says Japan's concrete sea walls were not built to handle such high waves. Experts say early warning systems will continue to be limited by these facts until earthquakes and tsunamis can be predicted Question: Where can this passage probably be adapted from? Yes or no, is the answer "A newspaper"?
A: No

Q: Article: Nicolai Calabria has already become one of the best 106-pound wrestlers. He has successfully climbed to the top of the highest mountain in Africa, and most importantly, he's changed the attitude of any normal person who watches him compete. The 17-year-old teenager has one leg. He was born that way, but his goal is to show it's not the one thing that defines him. He would also be the first one to tell you that he just wants to prove to others and himself that he's just like other normal ones. When Calabria was young, his parents tried different prostheses to find out which was most comfortable for their son as he tried to keep up with the family, who has a preference for sports. At first, the Calabrias had their middle child in a prosthesis that looked and functioned like a real leg, but soon they decided to choose a different path when they found it wasn't beneficial to his movement. Then the family moved him to arm crutches and from there a new burst of energy was found. Getting others to believe that he could take off on the soccer field took a little bit longer. When the Calabrias moved to Concord, they had a hard time persuading the town soccer team to allow a child like him to compete with able-bodied kids. After months and months of debates and meetings, the family received the answer they were looking for. Since then, witnessing a young man on crutches who competes against those with two legs has become _ in the Concord community. "At that time I had nothing but discouragement working with the soccer community; however, now I have nothing but admiration for the fact that he's been allowed to play, and people see that he adds value to game," his father said. "I just think it's a great result." Question: This passage shows us a boy with one leg _ . Yes or no, is the answer "can do what a normal teenager can"?
A: No

Q: Article: I am a 21-year-old boy, and this is my story. One month after I graduated from high school in 2009, I was coming home from swim practice and was involved in a car accident. I was so seriously injured that I was in a coma for over two months at Prince Georges Hospital. I died eight times during my coma and I couldn't talk or communicate when I woke up. Walking was never going to happen again due to all the extreme injuries. Just like my body, my dreams were almost _ . But I was not going to let my injuries prevent me from living my dreams. After 14 operations and blood transfusions, I had to learn how to talk, eat, walk, shower and live independently again. When I was out of hospital, I still had to go to outpatient therapy in Waldorf, Maryland. After spending a few months in a wheelchair, I took baby steps to walk on my own. It was a miracle that I could walk again, but I wanted to prove that I could not only walk, but run. When it came true, I wanted to get back in the pool again. After a few lung tests, I was able to go in the pool a little bit each week. After a few months of swim training, I began my freshman year at St. Mary's College of Maryland and became a proud member of the swim team. By telling my story, I want to make a positive influence on the world. I am just trying to live each day to the fullest and inspire other people never to give up their dreams no matter how bad a situation is. I remember when I was still in my hospital bed, I would have my mom and dad push me around in my wheelchair to the other rooms to see the other patients and talk to them and their families. I wanted to let them know that everything was going to be okay. Somehow, things would work out for the best. Question: When the car accident happened, the author _ . Yes or no, is the answer "had finished his high school education"?
A: No

Q: Article: The Royal Commission on Environmental Pollution has just published a report on new materials and has looked at the case of nanotechnology , which describes the science of the very small. Nanotechnology covers those man-made materials or objects that are about a thousand times smaller than the microtechnology we use, such as the silicon chips of computers. Nanotechnology gets its name from the nanometer, which is a billionth of a meter. There are about 600 consumer products already on the market that use nanotechnology. Nanomedicine is also being developed to fight cancer and other fatal diseases. The Royal Commission found no evidence of harm to health or the environment from nanomaterials, but this "absence of evidence" is not being taken as "evidence of absence". In other words, just because there are no apparent problems, this is not to say that here is no risk now or in the future. The commission is concerned about the pace at which we are inventing and adopting new nanomaterials, which could result in future problems that we are ill-equipped to understand or even find with current testing methods. One of the problems about nanotechnology is that when we make something very small out of a well known material, we may actually change the functionality of that material even if the chemical composition remains the same. Indeed, it is not the particle size that should concern us, but its functionality. Take gold, for example, which is a famously inert substance, and valuable because of it. It doesn't rust or corrode because it doesn't interact with water or oxygen. However, a particle of gold that is between 2 and 5 nanometers in diameter becomes highly reactive. This is not due to a change in chemical composition, but because of a change in the physical size of the gold particles. How can a change in size result in a change of function? One reason is to do with surface area. Nanoparticles have relatively a much bigger surface area. It is like comparing the surface area of a basketball with the total surface... Question: Which process explains that there might be risks in nanotechnology? Yes or no, is the answer "expand surface area -increase interactivity - change functionality-cause possible dangers"?
A: Yes
