Write a multi-choice question for the following article, with the given choices and answer: 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... Options: A expand surface area -increase interactivity - change functionality-cause possible dangers B expand surface area - change functionality - increase interactivity -cause possible dangers C increase interactivity - expand surface area - change functionality-cause possible dangers D increase interactivity - change functionality - expand surface area-cause possible dangers Answer: A expand surface area -increase interactivity - change functionality-cause possible dangers Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Most people report that they do not usually feel confident. But exciting things can happen when we actually believe in ourselves. Here is a man who believed in his own ability even as a boy, and that confidence helped shape his adult life. At the turn of the last century, a young boy quit school to help with the family expenses. When he was fifteen, he became interested in automobiles and worked in a garage. He subscribed to a correspondence home study course on automobiles and, after a long day in the garage, studied at the kitchen table by lamplight. When he felt ready, he walked into the Frayer-Miller Automobile Company of Columbus, Ohio. When Mr. Frayer noticed him, he asked, "Well, what do you want?" "I just thought I'd tell you I'm coming to work here tomorrow morning," the boy replied. "Oh! Who hired you?" "Nobody yet, but I'll be on the job in the morning. If I'm not worth anything, you can fire me." Early the next morning the young man returned to the plant. Noticing the floor was thick with metal shavings and accumulated dirt, the boy got a broom and set out to clean the place. Because of his self-confidence and work ethic, the boy's future was predictable. He went on to stand out in many fields, including automobile racing, piloting World War I planes and founding what was to become one of America's largest airline companies -- Eastern Airlines. People who become more confident habitually encourage themselves. Without confidence, we are not likely to move far in the direction of our dreams. But become our own best friend and almost anything will be possible. It is important that we always believe in ourselves. In order to reach victory, we must believe in ourselves even when we make mistakes and fall short. Options: A He attended school in the daytime. B He studied hard at home. C He read books in the garage where he worked. D He turned to some instructors for help. Answer: B He studied hard at home. Question:
A: How did the boy learn knowledge concerning automobiles?

Write a multi-choice question for the following article, with the given choices and answer: Article: The desire for a better life is sometimes so big that it makes people leave their countries and their families and work in other countries. They know that they will have to face difficult moments, that they won't be able to communicate with the persons around them, and that they have to work in illegal conditions to get the money they need for their families, but they all take these chances and they hope they will succeed. On the other hand, there are people who immigrate just for the sake of the people they love. They leave their families to make other families with the people they love. Women go to meet their men who have chosen other countries to start a new life, even if they miss their families and friends. Maybe they don't have a place to work but they are able to wait to see what destiny has for them. There are also the cases of the people who are forced to leave their countries because of a war which threatens their lives. They'd rather start from the very beginning again than risk putting their lives in danger. When well-developed countries see that their homeland is being "invaded" by lots of immigrants, they set new laws that make immigration harder. As a result of this, many illegal immigrants cross the borders and are eager to work, although they are paid only half the amount of money native workers receive for the same kind of job. The opinions of the local people are varied and they range from total refusal to complete acceptance. Immigrants in countries which have large communities of them are fighting for the recognition of their social rights and for equal treatment. Many immigrants have managed to be fully accepted by the communities where they live and have managed to change the opinions of the local people about them. Options: A Escaping from a war. B Being reunited with the beloved people. C Seeking a better life D Studying a foreign language Answer: D Studying a foreign language Question:
