Question: Write a multi-choice question for the following article, with the given choices and answer: 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."

B The sudden eruption of the volcano. C The lack of professional equipment. D The rough and steep slope of the hill. Answer: A The rocks and dust raised by boards. Question:

Question: Write a multi-choice question for the following article, with the given choices and answer: Article: "If we can set it up so you can't unlock your phone unless you've got the right fingerprint ," Barack Obama asked last Tuesday, "why can't we do the same thing for our guns?" For this reasonable-sounding question, the president was praised throughout the media. As it happens, though, there is a good answer to this question: there is no market for guns that work just some of the time. Guns are simple things designed to operate as easily and reliably as possible. The introduction of electronics eats away this simplicity, and to a degree that is absolutely unacceptable to the consumer. As President Obama well knows, the fingerprint software on his phone works rather _ : Often it takes a user two or three tries to log in; occasionally, it falls asleep deeply and obeys the password. When this happens on an phone, the user is mildly inconvenienced. If this were to happen on a gun, the user would be dead. There is a reason that modern smartphones put the camera function outside of the authentication process. How could we possibly think that guns are the same as other commercial products? It is true that, say, cars have become considerably safer over the last few decades; true, too, that "research" has contributed to this improvement. But it matters enormously that a car is not intended to hurt people, and that in a perfect world nobody would ever be injured by one. Can we say the same of guns? Of course not. Guns are killing machines, designed to do damage to living things. In fact, they have no other purpose. As such, the salient question before any free people is not "are guns dangerous?" they are, but "who gets them, and why?" This is not to say that nothing at all can be done to improve public safety. On an individual level, gun owners should do everything to ensure that their guns are kept away from children, and, where possible, they should train themselves in case they are ever called upon to shoot in anger. At the national level, the combination of better policing and economic growth can help to reduce... Options: A Gun crime has been greatly reduced. B The idea of smart guns is not realistic. C Gun control will not succeed in America. D Guns-related deaths deserve public attention. Answer: B The idea of smart guns is not realistic. Question:
Answer:
What does the writer mainly argue in this passage?
