input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Space is a dangerous place, not only because of meteors but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is necessary for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage. Radiation is the greatest known danger to explorers in space, The unit of radiation is called "rem" Scientists have reason to think that a man can put up with far more radiation than 0.1rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage. A person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of _ children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and , during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far. Options: A exposure to even tiny amount of radiation is fatal( ) B the effect of exposure to radiation is slow in coming C radiation is avoidable in space exploration D astronauts in spacesuits needn't worry about radiation damage Answer: B the effect of exposure to radiation is slow in coming Question:???

Write a multi-choice question for the following article, with the given choices and answer: Article: People have always been wondering about what our future will look like. Go on reading this text, and you will know what will happen in the next fifty years. How can we know what the future will look like? To be able to understand the future, you must know the past. What has taken us to where we are today and what has changed along the way? The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago. Will this change in the next 150 years? No. What inventions have really made a difference in the last 150 years? In the past years, the inventions that have affected most people around the world for everyday living are the telephone, electricity, radio, television, computer, the car and the ability to communicate through the Internet. Then we of course have a lot of inventions that have made life easier, like new medicine, faster transports etc. In general, human beings have been working hard in the last 150 years to make the inventions so that they will be able to get control of the time and the world. Since there is still much to do in this area, this will be the focus at least for the next 150 years. Why do we need to predict the future? Predicting the future is important for two reasons first we need to start to think about what kind of future we would like for ourselves and to pass on to the next generation, and then we need to know what decisions we need to make today that will give the best result in the future. Options: A it easy for us to live B our daily life more stressful C our work easily done D us work less time Answer: A it easy for us to live Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: Spider webs are one of the most fascinating examples of animal architecture. The most beautiful and structurally ordered are the round webs. The main function of the web is to stop and hold flying insects,long enough for the spider to catch them. In order to do so,the threads of the web have to stand the forces from large and heavy insects as well as environmental forces from wind and rain for at least a day in most cases. The round web is found to have two main characteristics. The first is its geometry,which consists of an outer frame and a central part from which threads radiate outward. Enclosed in the frame are capture spirals winding round and round from the web center out to the frame. The whole web is in tension and held in place by anchor threads,which connect the frame to the surrounding plants or objects. The second and perhaps most important characteristic is the material with which it is built. Spider silk is a kind of natural material that gives this lightweight fiber a strength comparable to that of steel, while at the same time making it very elastic . Two types of silk threads are used in the web. One is highly elastic and can stretch to almost twice its original length before breaking and, for most types of spiders, is covered in glue. This type is used in the capture spiral for catching and holding insects. The other is stiffer and stronger,and is used for the radius,frames and anchor threads,which allows the web to stand forces and to keep its structural strength through a wide range of environmental conditions. Options: A The wisdom of spiders. B The function of round spider webs. C The structure of round spider webs. D The challenges for spider webs. Answer: C The structure of round spider webs. Question:
A: What is this passage mainly about?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: BERLIN (Reuters)--Germany's postal service has announced plans to explore improved service and help protect the environment by getting "fetch friends"--ordinary people traveling across cities--to deliver parcels on their way. It is hoped that the move, which will be tested in the coming months, might lessen traffic in inner cities and reduce CO2emissions . This should help DHL, a division of the German postal service, reach its target of improving the company's carbon efficiency by 30 percent before 2020. "As the world's biggest logistics provider, we recognize a special responsibility to reduce the impact on the environment as much as possible," said Frank Appel, Chief Executive Officer of Deutsche Post DHL, in a statement referring to a variety of measures being considered. The "fetch friends" find out online about parcels that need delivering to people who live or work along the way that they are planning to travel through the city. They then select the ones that they want to take. Codes sent to their mobile phones tell the volunteers where to pick the packages up. Parcels can be taken part of the way or passed on to another volunteer but all volunteers need to have the right code on their mobile phone so the track and trace system can be updated. Logistics companies will be responsible for looking after the operation to make sure that the privacy of post is respected. It's hoped that this could be done using mobile phones but DHL says it recognizes that some security issues remain to be worked out. Options: A has been tested for months B aims to reduce the cost of the service C employs environmentalists to help with deliveries D encourages ordinary people to help cut the carbon footprint Answer: D encourages ordinary people to help cut the carbon footprint Question:
