Question: Write a multi-choice question for the following article: Article: If two scientists at Los Alamos National Laboratory are correct, people will still be driving gasoline powered cars 50 years from now, giving out heat-trapping carbon dioxide into the atmosphere--and yet that carbon dioxide will not contribute to global warming. In a proposal by two scientists, vehicle emissions would no longer contribute to global warming. The scientists, F. Jeffrey Martin and William L. Kubic Jr., are proposing a concept, which they have named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline. The idea is simple. Air would be blown over a liquid solution of potassium carbonate, which would absorb the carbon dioxide. The carbon dioxide would then be put to chemical reactions that would turn it into fuel : gasoline or jet fuel. This process could change carbon dioxide from an unwanted, climate-changing pollutant into a vast resource for renewable fuels. The cycle--equal amounts of carbon dioxide produced and removed--would mean that cars, trucks and airplanes using the synthetic fuels would no longer be contributing to global warming. Although they have not yet built a synthetic fuel factory, or even a small model, the scientists say it is all based on existing technology. "Everything in the concept has been built, is operating or has a close cousin that is operating." Dr. Martin said. The Los Alamos proposal does not go against any laws of physics, and other scientists who have independently suggested similar ideas. Dr. Martin said he and Dr. Kubic had worked out their concept in more detail than former proposals. There is, however, a major fact that explains why no one has built a carbon-dioxide-to-gasoline factory: it requires a great deal of energy. According to their analysis, their concept, which would cost about $5 billion to build, could produce gasoline at an operating cost of $1.40 a gallon and would turn economically practical when the price at the pump hits $4.60 a gallon. Other scientists said the Los Alamos proposal perhaps looked...

Question: Write a multi-choice question for the following article: Article: WASHINGTON -- President Obama brought together the leaders of Japan and South Korea to discuss cooperation on containing North Korea and its nuclear weapons programs. Japan and North Korea have had tense relations over unresolved issues, some of them dating back 100 years. The three leaders emphasized the importance of cooperation in dealing with North Korea. The meeting took place Tuesday in the Hague, after a twoday nuclear security summit. President Obama praised South Korean President Park Geunhye and Japanese Prime Minister Shinzo Abe for overcoming their differences to discuss a serious threat to regional peace. He emphasized the importance of cooperation on the North Korean nuclear issue. Obama said the three discussed steps to deepen diplomatic and military cooperation, including joint military exercises and missile defense against Pyongyang. He said further discussions would take place next month, during his visits to Seoul and Tokyo. The South Korean president stressed the importance of a united response to North Korea, but also called on the North to choose a peaceful path. "I sincerely hope that this meeting will offer a chance for us to reconfirm our trilateral coordination and strengthen the cooperation on the nuclear front," said Park. Japanese Prime Minister Shinzo Abe agreed. "Particularly it is extremely important that we were able to confirm close cooperation among Japan, the United States and the Republic of Korea on the issue of North Korea, the three countries who would like to cooperate so that North Korea will be able to take a positive position with regard to nuclear and missile issue," said Abe. Japan and South Korea have several unresolved issues, including Japan's refusal to apologize again for crimes committed 70 years ago. Former U.S. diplomat Richard Armitage told an audience this week that painful historic injustices take a long time to heal, and that it is in Japan's interest to continue apologizing for as long as necessary. "There is a historical record of enormous...

Question: Write a multi-choice question for the following article: Article: There are two ways to save money traveling. The first way is to get _ on the specific things you want. There is a limitation to this type of approach (,) though. If you find the lowest price on the best hotel in Honolulu at the height of the season, you will save money, but still have a very expensive vacation. Trying to get exactly what you want will generally be an expensive proposition, in travel and in life. The other approach is to be a true opportunist. This will be difficult for some of you, and entirely unacceptable to others. Nonetheless ,the travelers who get to travel the most, go to the widest variety of places, learn the most and do the most, are the opportunists. This will be true until you are so wealthy that you have no monetary (;)limits. The first time I went to Ecuador, I went there because it was cheap. If it wasn't, I would have had a great time--somewhere else. The trip lasted a month, and cost $1045, which included airfare and even the $130 fee for a guide to take me to the top or glacier covered Mount Chimborazo. I cut the cost by taking a bus from my home in Michigan to Miami, and back again when I returned from Ecuador. The round-trip ticket cost $158. The round-trip flight to Quito from Miami was only $256, because it was a courier (,) flight, which meant I signed for some luggage(car parts), and could only take carry-on luggage. Never did I feel deprived, or bored. I had a great time, eating wherever it was cheap and clean, doing all sorts of inexpensive, but interesting things, and traveling across the country to climb Chimborazo. I also met and fell in love with my wife Ana. Being an opportunist means you'll have just as much variety, and probably almost everything you want--eventually. You just have to stop trying to get exactly what you want exactly when you want it. If the guide that took me up Chimborazo hadn't dropped his price from $200 to $130, I would have spent $2 for a bus and gone hiking on EI Altar, another great Andean mountain. That would have left me with...
