input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Today we have the second report explaining how to prepare fish by drying or smoking them. We talked last week about the first steps of cleaning and salting freshly caught fish. To dry fish, you will need either a drying table or a place to hang them. If a table is used, it should have a top made of wire screen or thin pieces of wood with space between each piece. Lay the cleaned, wet salted fish on top of the table. Do not let them touch each other. Be sure that air can reach the fish from all sides. _ Turn the fish over every other day. Small fish will dry in about three days if the air is dry. Large fish will take a week or ten days to dry. After the fish have dried, place them in a basket. Cover them with clean paper or large leaves. Then put the basket in a cool, dry place off the ground. Make sure as much of the saltwater as possible is removed before you smoke the fish. The smoking can be done in a large, round metal container. Remove the top of the drum and cut a small opening on one side at the bottom. Cover the top with a strong wire screen, where you put the fish. Build a small fire in the drum by reaching in through the opening at the bottom. Wood from fruit trees makes good fuel for your fire. _ will give the smoked fish good color1 and taste. One way to get a lot of smoke is to use green wood, not dried wood. You should smoke the fish for five days or longer if you plan to keep them for a long time. After that, wrap them in clean paper, put the fish in baskets and keep them in a cool, dry place off the ground. Options: A To smoke fish, you have to salt the fish first. B Smoked fish can only be kept in a basket. C You'd better use dried wood to smoke fish. D Smoked fish taste better than dried fish. Answer: A To smoke fish, you have to salt the fish first.

Write a multi-choice question for the following article, with the given choices and answer: Article: Besides providing an ideal environment for sea plants and animals to live in, seawater has other values, one of which is that it constantly moves, and its movements produce energy. The most obvious movements are waves and the tides. Winds causes the waves, and the gravitational pull of the moon and the son causes tides. In places like the Bay of Fundy in Canada, the difference between the high and low tide level can be as much as 40 feet. France and Britain are now trying to use energy in the tides to produce electricity. Waves can produce electricity and some experiments are taking place to learn more about this. One of the most encouraging areas of research uses the difference between the temperature of seawater at the surface and deep down to produce electricity. Options: A The temperature difference of seawater can produce electricity. B The energy in the tides can produce electricity. C Waves can produce electricity. D The plants and animals in the ocean can produce electricity. Answer: B The energy in the tides can produce electricity. Question:

Q: Write a multi-choice question for the following article, with the given choices and answer: Article: "I've changed my mind.I wanted to have a telescope,but now I want my dad back." Lucien Lawrence's letter to his father for Christmas written after his father had been knifed to death outside his school gate,must have touched everyone's heart.Lucien went on to say that without his father he couldn't see the stars in the sky.When those whom we love depart from us,we cannot see the stars for a while. But Lucien,the stars are still there,and one day,when you are older and your tears have gone,you will see them again.And,in a strange way,I expect that you will find your father there,too,in your mind and heart.I find that my parents,who died years ago,still figure in many of my dreams and that I think of them perhaps more than I ever did when they were alive.I still live to please them and I'm still surprised by their reactions.I remember that when I became a professor,I was so proud,or rather so pleased with myself that I couldn't wait to cable my parents.The reply was a long time in coming,but when it did,all my mother said was "I hope this means that now you will have more time for the children!" I haven't forgotten.The values of my parents still live on. It makes me pause and think about how I will live on in the hearts and minds of my children and of those for whom I care.Would I have been as ready as Philip Lawrence have been to face the aggressors,and to lay down my life for those in my care?How many people would want me back for Christmas?It's a serious thought,one to give me pause. I pray silently,sometimes,in the dead of night,that ancient cry of a poet "Deliver my soul from the sword,and my darling from the power of the dog." Yet I know the death comes to us all,and sometimes comes suddenly.We must therefore plan to live forever,but live as if we will die tomorrow.We live on,I'm sure,in the lives of those we love,and therefore we ought to have a care for what they will remember and what they will treasure.If more parents knew this in their hearts to be true,there might be fewer knives on our streets today. Options: A to leave a precious memory to those he loves and cares for B to have a high sense of duty to the whole society C to care for what others will remember and treasure D to share happiness and sadness with his family Answer: A to leave a precious memory to those he loves and cares for Question:
A: In the author's opinion,the value of a person's life is _ .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: On April 24th, another natural disaster-the oil spill in the Gulf of Mexico, happened. Millions of dollars have been used to help stop the spill and to clean up the animals, beaches, and land spoiled by the oil. Unfortunately, when many of these chemicals are used, more damage is caused to the environment, especially to lives in the sea. But governments seem to accept the _ of transporting mil-lions of tons of oil by ship every day so that we can fill up our cars and drive around and cause even more environmental damage. Interestingly, the biggest companies in the world produce cars, and the next biggest supply the gasoline to make them run. Of all of today's environmental disasters, an oil spill may actually be one of the least serious. Although oil is poisonous, it is a natural material. In the end, it breaks down naturally. In 1967 the tanker Torrey Canyon sank off the Scilly Isles near the coast of England and spilled 120,000 tons of oil into the ocean. If you go there today, you will find it hard to see any sign that it ever happened. However, we should be thinking more about reducing our dependency on oil. Governments should be encouraging research into new technologies, such as cars run by solar power, electricity, hydro-gen, and so on. Much of this research, in the past, was stopped by the oil, gas, and coal. If the world's millions of cars were 10% more efficient ,we would need many fewer tankers crossing the oceans each year. If this happened, the risks of oil spills would be reduced, and the air we breathe would be cleaner and fresher, too. Options: A Oil spills pollution. B What oil pollution is. C Oil tanker accidents. D How to reduce oil pollution. Answer: A Oil spills pollution. Question:
