input with options: Read the following article and answer the question. Article: Sometime early in the next century, human beings will move to Mars. They will live there for about a year, and then will be replaced with another group of pioneers. Building the base on Mars will advance our knowledge of the solar system and aid in our understanding of the earth. We already know that Mars resembles the earth in many aspects: general size, presence of water, length of day, range of temperatures. These resemblances have caused many people to consider a centuries-long project: to terraform Mars. Terraforming means _ a planet's surface so that Earth's life forms can survive there. This concept, previously found only in science fiction is now being seriously considered by scientists. Terraforming Mars is theoretically simple: add nitrogen and oxygen to the atmosphere; pump water to the surface; and add the earth's plants and animals in the order in which they developed on Earth. But it will take at least 300 years. Some people think that such a project is too huge for humans to undertake, but there are very good reasons to make the attempt. The earth now contains some 6 billion people, and no one has any idea of how many humans the earth can support. Our very existence and numbers are threatening many other species. We also have had some experience with terraforming our own planet: altering the landscape, the atmosphere and the climate. Currently terraforming earth has become a wiser activity as we try to control global warming, air and water pollution, and preserve some natural living places. While the possibility of such a project is small, it is not impossible .Even if earth -bound societies come and go in the next 300 years, the project can continue through the work of the Mars settlers without the need for constant backing from the earth. The future existence of all the people in our world may very well depend upon our ability to terraform Mars. Question: According to the passage the main purpose of terraforming Mars is to _ . Answer:
OPTIONS:
- do some scientific research work
- find out its similarity to earth
- avoid the dying away of many other species
- find on Mars living place for the increasing human beings
output: find on Mars living place for the increasing human beings

input with options: Read the following article and answer the question. Article: To swim across the English Channel takes at least nine hours. It's hard work and it makes you short of breath. To fly over the channel takes only twenty minutes as long as you're not held up at the airport, but it's an expensive way to travel. You can travel by hovercraft if you don't mind the noise and that takes forty minutes. Otherwise, you can go by boat, if you remember your sea-sickness pills. All these means of transport have their problems, and the weary traveler often dreams of being able to drive to France in his own car. "Not possible, you say. Well, wait a minute. People are once again considering the idea of a channel tunnel or bridge." This time, the great London Council is looking into the possibility of building a channel link straight to London. A bridge would cost far more than a tunnel, but you would be able to make a journey by rail or by car on a bridge, yet a tunnel would provide a rail link only. Why is this idea being discussed again? Is Britain realizing the need for links with Europe as a result of joining EEC?Well, perhaps, the main reason, though, is that a tunnel or bridge would reach the twenty square kilometers of London's discussed dockland . A link from London to the continent would stimulate trade and revitalize the port, and would make London a main trading center in Europe. With a link over the Channel, you could buy your fish and chips in England and be able to eat them in France while they are still warm! Question: A tunnel would cost _ a bridge. Answer:
OPTIONS:
- far less than
- as much as
- far more than
- as little as
output: far less than

input with options: Read the following article and answer the question. Article: After my husband died suddenly from a heart attack, my world crashed around me. My six children were all under 10, and I was burdened with the responsibilities of earning a living, and caring for the children. I was fortunate to find a wonderful housekeeper to care for the children during the week, but from Friday nights to Monday mornings, the children and I were alone. One Friday evening I came home from work to find a big pretty German Shepherd on our doorstep. This dog seemed to intend to enter the house. The children liked "German" immediately and begged me to let him in. I agreed to let him sleep in the basement. That night I slept peacefully for the first time in many weeks. The following morning we made phone calls and checked lost-and-found ads for German's owner, but with no results. On Sunday I had planned to take the children on a picnic. Since I thought it best to leave German behind in case his owner came by, we drove off without him. When we stopped to get gas, we were amazed to see German racing to the gas station after us. No way was he going to be left behind. Monday morning I let him out for a run. He didn't come back and we were all disappointed. We were convinced that we would never see him again. We were wrong. The next Friday evening, German was back on our doorstep. Again he stayed until Monday morning, when our housekeeper arrived. This pattern repeated itself every weekend for almost 10 months. We grew more and more fond of German. We took comfort in his strong, warm presence, and we felt safe with him near us. As German became part of the family, he considered it his duty to check every bedroom to be sure each child was cozy in bed. Each week, between German's visits, I grew a little stronger, a little braver and more able to handle; every weekend we were no longer alone and enjoyed his company. Then one Monday morning we patted him on the head and let him out for what turned out to be the last time. We never saw German again. Question: Which of the following can't be used to describe the dog? Answer:
OPTIONS:
- Loyal
- Beautiful.
- Lovely.
- Wild.
output: Wild.

Article: It came with devastating force,a natural disaster of strange intensity that shocked the world and killed tens of thousands.The waters have now receded,but disease and food and water shortages trouble a number of countries around the Indian Ocean.Millions of survivors face serious problems. The number of survivors in need of food aid after the Indian Ocean disaster has climbed to 5 million people.They stretch from Somalia to Thailand,and the figure could rise further,the United Nations has said. Relief teams hope to reach all of the estimated 700 000 hungry in Sri Lanka within three more days.It could take longer before enough food aid gets to the nearly 1 million people in need in hard-to-reach parts of Indonesia.Another serious problem is the need for purified water. Although aid had poured in from all over the world to the disaster areas,"Logistics is the big problem here--just getting the stuff out to people who need it,"said Ron Libby,emergency management specialist at the USA agency for International Development. Relief efforts are hindered by the difficulty of delivering aid to the more than 1000 islands scattered across hundreds of kilometers of ocean. For those who survived the tsunami's force,disease is now the No.1 problem.Five million people are short of water,food and basic sanitation across the region.World Health Organization(WHO) crisis chief David Navarro said 50 000 more people could die from disease and other causes,as has been the case in previous humanitarian emergencies. WHO said it had already received a handful of reports of malaria and dengue fever and hundreds of reports of diarrhea and infected wounds.It said millions of water purification tablets had been sent to Asia,along with sanitation engineers to rebuild water sanitation infrastructure. Psychologists are warning that mental health problems caused by the tsunami could prove harder to resolve than the physical damage. Some survivors say they are plagued by recurring nightmares about walls of water.Many locals are afraid to... Question: This passage is mainly about _ that happened around the Indian Oceans. Answer:
