Article: A 1. 6-meter tall robot may soon become the best friend for lonely elderly people,as Chinese scientists are making the final sprint toward its market launch ,said a senior researcher on the robot project on Saturday. "We are working on testing the exact functions and ways to reduce the cost in preparations for an expected market launch of the robot in two to three years,"said Li Ruifeng,a member of the project. He said the team hoped to reduce the cost so that the robot can be priced at 30,000 to 50,000 yuan,which is expected to be an affordable price for most of China's better-off families. The robot has been developed with the functions of fetching food,medicine,sounding alarms in case of water or gas leakage,sending texts or video images via wireless communications,and even singing a song or playing chess to entertain its masters. Li said that the robot,developed independently in China, has technology at the same level as those in western labs. China set about the research of the robot in 2007,when it was listed as a national key project. It is _ by government funding . China has the world's largest elderly population with 159 million people over 60,accounting for 12 percent of its total population. According to a survey by the Ministry of Civil Affairs,more than 10 million caregivers and nurses are needed to attend the elderly population,as most of Chinese elderly prefer to live their retired lives at home. Question: The author wrote the passage to_. Yes or no, is the answer "introduce a newly-developed robot caregiver"?

Ques: Article: During my travels through the mountains of Greece, I was only ever scared once. It was dusk and as I walked alone I came across six large wolves that were feeding on the body of a dead animal. I had heard many stories about wolves as a child and it was this animal that I feared more than any other. The wolves before me were huge, at least 6 feet long and covered with thick grey fur. As I went near, the wolves left the blood-covered snow that surrounded the body and started walking towards me, one after another. They stopped about 20 metres from me and stared. The lead wolf raised his head into the air and took in a deep breath, as if he was smelling my presence. The animals looked both beautiful and frightening, but I knew I could not show them my fear. As I drew nearer, the lead wolf raised its head once more but this time let out a long, loud cry. The awful cry rang out across the silent valley. I had never heard a more frightening sound. I was almost certain it was a sign to be death. Every moment I expected to see the pack of wolves dash at me, I knew my only hope was to pretend I had no fear. I walked past the line of wolves, like a general moving among his soldiers. They cried out loud again. But when they saw that their cry did not cause me to change my direction or make me run they feared to come after me, so they let me pass and returned to the dead animal. If I had turned back or tried to run away when they marched out to meet me, I am certain the whole pack would have attacked me in a moment. But my show of false courage scared them and kept them back. Question: What is the author's intention in writing this story? Yes or no, is the answer "To stress the need for courage when in danger."?
Ans: Yes

Article: Human beings have a natural desire to explore the unknown. People with a strong interest in space like to say it is the last place left to explore. But scientists are warning that space exploration for long periods is not going to be easy. They say the human body is not designed to stay in space over an extended period. The New York Times recently published a report about scientists who are preparing astronauts for a trip to the Moon. The newspaper said the scientists want to make sure that their crews return home in good health. But there are many problems to be solved before people are ready for long trips to the Moon, an asteroid or even the planet Mars. Humans developed on a planet with a surface that is more than 70 percent water. Our bodies are also about 70 percent water. When there is no gravity that water moves up toward the head, raising pressure in the skull. Arms and legs grow weaker at what is called zero gravity because they no longer need to push against the force of gravity. Five years ago, astronauts who spent weeks in space reported a change in their eyesight. These astronauts were members of the crew on the International Space Station. Research showed a change in the shape of their eyes. Normally-round eyeballs had become flat during time in space. The research also showed that the right eye was affected more than the left, and that men were more affected than women. Scientists could not find an explanation for the differences. Bone loss was one of the problems first reported by astronauts returning to Earth after longer stays in space. So scientists designed exercise machines to use on the space station. Tests showed that the exercise equipment helped space travelers keep their bones almost as strong as when they left Earth. There are other health issues for astronauts who spend a long time in space. They may have problems eating and sleeping. But the biggest health issue is exposure to radiation. On Earth, human beings are protected by the atmosphere and the planet's magnetic field. In... Question: What is the main idea of the passage? Yes or no, is the answer "Long periods in space will affect the health of astronauts."?
No
