I'm taking a test and have to guess the right answer to the question after the article. Article: After a year of being prepared, Laura Dekker can't wait to set sail .Last August ,the Dutch government decided that Laura Dekker was too young to take on the challenge of sailing around the world alone. But after a year of preparing herself , Laura has been allowed to sail. "I was so happy I almost jump into the water," Laura said , after learning of the court's judgement. She was born on a yacht in the South Pacific ,and now lives with her father in a boat. When Dutch child protection groups first heard about her plan to sail alone , they stopped her from doing so . Since the decision, though, Laura had been preparing with her father to persuade the courts that she was ready. Last week she received the books and other materials she would need for school while she was at sea. She added safety equipment to a new, big ship. And she took her first aid course to learn several survival skills, like how to put out fires on the boat, take care of her own injuries and deal with lack of sleep. She also planned a safer course --- adding alternate routes to avoid pirate attacks, and planning a course that would have her on dry land as she moved from port to port across the world. Laura is using a larger and more safer boat. If she finished successfully in less than two years, she will take the title from current record-holder Jessica Watson, of Australia, who was 16 when she completed the journey. Question: Why didn't the Dutch government allow Laura Dekker to sail alone ? Options: A: She was too old to take care of herself B: She was too young to sail alone. C: She was not well prepared D: It would cause trouble to the government.

I'm taking a test and have to guess the right answer to the question after the article. Article: For many years,machines have been doing work that people once did,including some dit- ficutt jobs. Search and rescue operations in dangerous environments are often seen as the first areas that will employ high technology robots. But there is another area where they may soon take jobs traditionally held by human beings: the restaurant industry. Teams from around the world competed in early June at the DARPA Robotic Challenge Finals in California. A team from South Korea and its robot,called DRC-Hubo,won the first place in the competition. The second and third place winners were from the United States. The robots were required to drive a vehicle,climb up steps and do mechanical work. Such activities are easy for humans to perform,but more difficult for machines. Not all of the competitor were successful. The failures showed how difficult it is to design effective walking machines. Akihiro Suzuki works at Yaskawa Electric,a company that develops robots. He says robots cannot do everything a human can,but they are able to work without becoming tired. He says robots cannot taste food,change heating levels or seasonings to get the best flavor .But he says if a food can be easily prepared,a robot can repeat the same movement to reproduce the same meal. One Japanese woman who saw the robots working wanted to bring them home. Masayo Mori says she would like to have a husband who could work like a robot. Suzumo Machinery showed its sushi maker robot. It performs the often difficult work of wrapping the popular Japanese food. Hiroshi Monden is an official with the company. He says people all over the world now eat sushi,but there are not enough skilled workers to prepare it. He says his machine can help anyone make sushi. Question: Why did some teams fail at the DARPA Robotic Challenge Finals? Options: A: Their robots cannot be applied at home. B: Preparing food is really difficult for robots. C: Their robots can just repeat the same movement. D: They failed to design effective walking robots.

I'm taking a test and have to guess the right answer to the question after the article. Article: Last month, the president of the Maldives, Mohamed Nasheed, held an underwater meeting. The purpose of the ocean floor conference? To highlight the effects of global warming on his island nation. The Maldives, located in the Indian Ocean, is the lowest-lying country on Earth. Melting glaciers and polar ice are causing sea levels to rise, putting the Maldives and other low-lying areas at risk of being swallowed by the sea within the next 100 years. What can be done? Scientists and leaders from 190 nations will try to figure that out at the United Nations climate change conference next month. The main goal of the meeting is to come up with a new climate agreement for 2012 and beyond. That is when the existing plan, the Kyoto Protocol will expire. The agreement was created in Kyoto, Japan, in 1997. Since then, it has been ratified by 190 nations. The countries promised to limit the amount of greenhouse gases, such as carbon dioxide, that they produced each year. The debate over who should cut greenhouse emissions has been going on for years. The US has been hesitant to reduce emissions unless fast-growing nations such as China and India also reduce their use of fossil fuels. In recent months, China has taken steps to be greener. But India has been unwilling to change. It argues that it is unfair for rich nations to ask poorer countries to cut down on emissions. While world leaders work on a plan in Copenhagen, there are many things you can do to help the planet. You can save fuel by walking or biking instead of riding in a car. You can start a recycling program in your community. You can plant trees. Trees absorb carbon dioxide from the air and give off oxygen. Question: According to the passage, limiting greenhouse emissions_. Options: A: will make poor countries poorer B: is well performed in the Maldives C: has been a controversial question D: means banning carbon dioxide emissions
