Q: Write a multi-choice question for the following article: Article: Nicaragua's Cerro Negro Volcano has erupted 23 times in the past 100 years,burying homes, crops and people in lava and ashes. But recently the black mountain has become a tourist draw, thanks to a newly invented extreme sport: volcano boarding. Thousands of thrill-seekers have climbed to the top of Cerro Negro, peered into its mouth, then zipped down its rough-and--rocky 41--degree slope on special boards. The volcano-boarding speed, set by an Israeli woman, is 54 mph. "Rushing down an active volcano is something that people expect." Said Anthony Alcalde, an expert volcano boarder. The sport was developed in the mid-2000s by Darryn Webb, an Australian who had climbed the nearby Cerro Negro but was looking for a faster way to get to the bottom. He tried sliding down on surfboards, snowboards, and even a refrgerrator door before inventing a sit-down board made of plywood. "At first, Darryn planned to use a snowboard," said Gemma Cope, a British woman who now runs Big Foot, which offers volcano boarding tours. "But he realized he couldn't cut an edge for there were little rocks everywhere. So he came up with the sitting-down option and realized he can go pretty fast. " Tourists,who are nearly all foreigners,pay $28 for the experience, which begins with a truck ride on dirt roads to Cerro Negr0.a 2,400-foot--high volcano that last erupted in l999.Visitors must carry their boards during the half-hour climb to the top. There,they go straight down the slope and sometimes they have to use their feet for brakes.Along the way.The board fills with rocks and dust,making boarders almost blind.Crashes are common."l wiped out twice and ripped my pants."said Melinda Vorisek, a tourist from Miami."But I'd do it again." Another tourist added:"It was sheer terror. I was eating dirt.But how many people can say they've bombed down a volcano?"
A: Question: what adds to the danger of volcano boarding according to the passge?Options:A The rocks and dust raised by boards.B The sudden eruption of the volcano.C The lack of professional equipment.D The rough and steep slope of the hill.Answer:A

Q: Write a multi-choice question for the following article: Article: Much older than the Great Wall, Stonehenge is one of the world's most fascinating, but least understood historical sites. Every year, thousands of tourists come to admire Stonehenge's beauty and to wonder about how and why it was built. Scientists have dated the site, which is located in prefix = st1 /England, to around 3000 BC. The stone circle was constructed in a number of stages over hundreds of years. It took millions of man hours to raise the heavy stones. Though there are many theories, it is still a mystery how stone-age man dragged such heavy stones over 380 kilometers from where they were made. Prehistoric people had only basic wooden tools. To move the stones they probably used tree trunks to roll them along. Some historians believe that Stonehenge was a temple, the site of ancient sacrifices . Others believe it was a burial place or perhaps even a giant sundial to tell the time. Whatever their ancient use was, the stones have always been a source of fascination for British people. One record from 1135 said the great stones were carried to Englandby giant magical creatures! In modern times Stonehenge has become a huge hit with tourists.
A: Question: It is believed by some historians that Stonehenge was built to _ .Options:A attract the British peopleB let people know the timeC exchange goods for daily useD create a living place for magical creaturesAnswer:B

Q: Write a multi-choice question for the following article: Article: Students who say they never or hardly ever used dictionaries may speak English well but usually write poorly, because they make many mistakes. The students who use dictionaries most do not learn especially well either. The ones who look up every new word do not read fast. Therefore they do not have time to read much. Those who use small two-language dictionaries have the worst problems. Their dictionaries often give only one or two words as translations of English. But one English word often has many translations in a foreign language and one foreign word has many translations in English. The most successful students are those who use large college edition dictionaries with about 100,000 words but do not use them too often. When they are reading, these students first try to get the general idea and understand new words from the context. Then they reread and use the dictionary to look up only key words that they still do not understand. They use dictionaries more for writing. If they are not sure how to spell a word, they always use a dictionary. Also, if they think a noun might have an unusual plural form, they check this in a dictionary.
A: Question: The writer thinks that _ .Options:A choose a good dictionary, and you'll be successful in learning EnglishB dictionaries are not necessary to the students who learn EnglishC it is very important for students to use good dictionaries properlyD using dictionaries very often can't help to improve writingAnswer:C

Q: Write a multi-choice question for the following article: Article: The following conversation is between Susan Russell-Robinson from the US Geological Survey and Barbara Reynolds from USA Today . Q: Why , after 600 years of no activity , did Mount Pinatubo in Philippines erupt in 1991 ? A: Volcanoes each have their own eruption styles . This volcano probably has a rule which makes it erupt in the order of every 500 to 1000 years , but a volcano in Hawaii seems to erupt every year , and some of the Alaskan volcanoes might erupt every 10 or 20 years . Q: So nothing caused it ? A: There's nothing out of the ordinary . If you were to take an ordinary calendar year , 50 to 75 or 80 volcanoes erupt around the world every year . There are 20 to 30 volcanoes every month that show signs of unrest . That might be a full-blown eruption or a whole host of activities like that . Q: What is "the ring of fire" ? A: If you look at where active volcanoes are placed around the world , there are somewhere between 500 and 600 of them . There is what appears to be almost a necklace that goes around the Pacific Ocean . It makes a ring where 60% of the world's volcanoes lie . Q: Why such a concentration there ? A: That's based on a theory that the oceans and the continents are like separate pieces . When continents and when that happens it seems to produce magma at depth and then you have volcanoes in the same ring .
A:
Question: Which of the following can be considered as the best conclusion of the conversation?Options:A There are so many volcanoes in the world and we are always in danger.B Volcanoes have erupted more frequently than ever before.C Volcanoes are waiting to be better known.D Something must be done to protect the people near the ring of fire.Answer:C
