Article: For a small town, Manhattan, Kansas has some big surprises. And one of them is the Holiday Inn Hotel, with rooms built around a swimming pool and a friendly family atmosphere. The Holiday Inn is where Manhattan people often go for a special party, or a night out. A lot of them choose to eat in the brightly lit restaurant near the pool. And many of them will be served by Ellen Logan, who has worked as a waitress here for more than two years . Ellen, like most of the waitresses, is also a student. She comes from Nebraska, but she's planning one day to be a veterinary surgeon, and to care for small animals. But in order to support herself at college, she works twenty hours a week at the Holiday Inn. Ellen soon learned what every waitress finds out. Your best friend has a good pair of shoes. She paid forty - five dollars for hers, much more than she would usually spend. She's discovered something else too. You don't have to know much about food to be a good waitress, but you do have to know a lot about people. "A lot of business people always stay here when they come to Manhattan, " she explains. "They like you to recognize them and remember their favorite dishes. But some couples come for a night out together. They just want to be left alone. Then there are people who can't make up their minds. They look down the menu and say'What do you suggest?'So I ask them how hungry they are. If they say, 'Not very', I suggest the salad bar, with soup, salad, bread, and a fruit plate. But if they say they're very hungry, I suggest a Kansas Strip Steak, with potatoes or rice. You get salad and bread as well. It's very nice. Real good value." Ellen may get tired feet sometimes, but at least she's learning too much about people . She'll probably make a good animal doctor, but if she find she doesn't like it after all, she can always become a psychiatrist instead." Question: From the passage we can infer that _ . Yes or no, is the answer "it is more important for the waitresses to know much about people than food"?
No

Article: Do you know what a castle is? A castle is a building special to Europe. Castles were built in the Middle Ages by king and other powerful people who live in. Castles were used by people to protect themselves from their enemies. They are big buildings made form stone and wood. Today there are still castles all over Europe. Some are in ruins. But some built later are still in good repair and used even today. One example is Windsor Castle, which is a home to the British queen. It is in the country or Berkshire, not far from London. Castles have walls around them. In the old days, soldiers would stand on the walls to guard the people in the castle. If enemies came they would shoot arrows and throw stones at them. Castles also had moats. A moat is a river around the wall that makes it difficult for enemies to get in. It could be either dry or filled with water. Other people from younger countries love European castles. In the US there are rich people who have brought broken parts of castles to their country and rebuilt them. And some people build "replica" castles---modern copies of Castle. You probably know the Disneyland Castle in California, US. But did you know it is based on a famous castle in Germany built by King Ludwig IIof Bavaria? Question: What does the passage mainly talk about? Yes or no, is the answer "Facts about castles."?
Yes

Q: Article: Down-to-earth means being honest, open, and easy to deal with. It is a pleasure to find someone who is down-to-earth. A person who is down-to-earth is easy to talk to. He or she accepts others as equals. A down-to-earth person may be an important member of society, of course, but they do not let their importance go to their heads, and they do not consider themselves to be better than others who are less important. Someone who is filled with self-importance and pride, often without cause, is said to have his nose in the air. There is no way a person with his nose in the air can be down-to-earth. Americans use another expression that is similar in some way to down-to-earth. The expression is both feet on the ground. Someone with both feet on the ground is a person with a good understanding of reality. He has what is called common sense. He may have dreams but he does not allow them to block his knowledge of what is real. The opposite kind of person is one who has his head in the clouds. A man with his head in the clouds is a dreamer whose mind is not in the world. Sometimes such a dreamer can be brought back to reality; sharp words from the teacher, for example, can usually get a daydreaming student to put both feet back on the ground. The person who is down-to-earth usually has both feet on the ground. _ . Someone with both feet on the ground may not be as open and easy to deal with as someone who is down-to-earth. When we have both our feet firmly on the ground, we are realistic and we act honestly and openly toward others, and our lives are like the ground below us, solid and strong. Question: From the passage, we can infer the person who is _ is the most popular kind of person. Yes or no, is the answer "down-to-earth"?
A: No

Q: Article: Boys and girls,as we all know,most people,especially young people ,tend to care about their hair much because hair plays a very important role in our appearance.But can you imagine what other uses hair has?Do you have any idea that human hair may become a new solar energy soutce?Before we begin with the new content of our Physics ,let me tell you a new invention first. It's reported that a Nepali teenager has designed a $32 solar panel using human hair. Milan Karki,who is 18 years old and lives in a village in rural Nepal,used human hair to replace silicon ,which is a common but expensive componet of solar panels. By using hair as a replacement,Karki says that solar panels can be produced for around $32,a price that could be halved if they were mass-produced. The solar panel works,because melanin ,which gives hair its colour,is light sensitive and can act as an elecrtical conductor.Kaiki was inspired to think of the idea by a Stephen Hawking book ,which explained how to create elecrtic energy from hair. The device that Karki has invented is capable of producing 9V or 18V of energy--plenty to charge a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months;whereas a pack of batteries would cost50p and lasts few nights,"according to The Daily Mail. The solar panel is claimed to be easy to service as the hair is easy to replace. Karki has now seng out several devices to other disrticts near his home for tetimg .He said,"First I wanted to provide elecricity for my home,then my village .Now I am thinking for the whole worle." So next time when you have a haircut,do remember to keep your hair cut down to use for energy.Perhaps you can also provide elecrticity for your home,even your village using your own hair. Question: Which of the following is true about the new invention? Yes or no, is the answer "The device can produce 9V or 18V of energy."?
A: Yes
