Read the following article and select the best answer. 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? - Their robots cannot be applied at home. - Preparing food is really difficult for robots. - Their robots can just repeat the same movement. - They failed to design effective walking robots.
They failed to design effective walking robots.

(Question)
Read the following article and select the best answer. Article: First lady's campaign brings change WASHINGTON (AP) -- Wal-Mart is putting special labels on some products to help shoppers quickly notice healthier ones. Millions of schoolchildren are helping themselves to vegetables from salad bars in their lunchrooms, and kids' meals at Olive Garden and Red Lobster restaurants come with a side of fruit or vegetables and a glass of low-fat milk. These changes are taking place due to the campaign against childhood fatness, for which the first lady Michelle Obama began fighting three years ago. Fatness has become a serious problem in the country. About one-third of U.S. children are overweight, which puts them at increased risk for any number of deadly illnesses, including high blood pressure and heart disease. Still, Mrs. Obama faces challenge. Not everyone welcomes her effort. Some blame her for going too far and say she has no right to tell what people should and shouldn't eat. But nutrition supporters and others praise her for using her influence to help bring interests to the table. They said the first lady has raised public awareness about fatness, which will help decrease childhood fatness rates. There is evidence of small decrease in childhood fatness rates in some parts of the country. New York reported a 5.5 percent drop in fatness rates in kindergarteners through eighth-graders between the 2006-07 and 2010-11 school years. In Philadelphia, the drop was 4.7 percent among students in grades K-12. Fighting against children fatness is hard work, but it's well worth the effort. The first lady is planning a promotional tour. She has been talking up the campaign against childhood fatness on daytime and late-night TV shows and on the radio. She also plans discussions next week on Google and Twitter. "We've been spending a lot of time educating and re-educating families and kids on how to eat, what to eat," the first lady said. "We're starting to see some changes and we're starting to show some improvement." Question: What can we learn from the passage about Mrs. Obama?? - She is an expert in healthy eating. - She has won support of the whole nation. - She shows great concern about childhood fatness. - She makes good use of media to increase her influence.
(Answer)
She shows great concern about childhood fatness.

Question: Read the following article and select the best answer. Article: Before you go to another country, it is a great help if you know the language and some of the customs of the country. When people meet each other for the first time in Britain, they say "How do you do?" and shake hands . Usually they do not shake hands when they just meet or say goodbye. But they shake hands after they haven't met for a long time or when they will be away from each other for a long time. Last year a group of German students went to England for a holiday. Their teacher told them that the English people hardly shake hands. So when they met their English friends at the station, they kept their hands behind their backs. The English students had learned that Germans shake hands as often as possible, so they put their hands in front and got ready to shake hands with them. It made both of them laugh. Question: English people usually shake hands when they _ . - meet every time - meet for the first time - say goodbye to each other - very bad
