*Question*
I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have documented how ant colonies choose their next queen--the female whose job is to produce eggs rather than seek food for others. New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned. Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide. David Hu who is a mechanical engineer with the Georgia Institute of Technology, also known as Georgia Tech, says, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at maintaining this network." David Hu and other Georgia Tech researchers want to study ants and the secret of their engineering. They freeze ant rafts and then look at them with the help of computed technology, or CT, images. The pictures show that larger ants serve in central positions to which smaller ants hold. The larger ants form pockets of air that keep the insects afloat. Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal. Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen. Question: What can we know from what David Hu said? Options: A: Ants know the way to keep a good figure. B: Ants know the way to join together tightly. C: Ants know the way to get along with each other. D: Ants know the way to form a harmonious society.

I'm taking a test and have to guess the right answer to the question after the article. Article: For years I fought with the bird's nest that sat on top of my head-my Medusa hair.No matter what I did and how hard I tried, in no way could I make my unruly hair to my satisfaction. Growing up in a Russian-Jewish home with parents who thought North American styling products were something illegal such as drugs, I was never allowed to put them in my hair. "Why buy hair gel? Your hair is so beautiful naturally." my mother would say.The teens at school did not agree.From boys' not wanting to kiss me when we played spin the bottle in Grade 7 to being called the mop, I suffered from my hair. When I got to university, I believed my hair was a wall that stood between me and everything---finding a part-time job, getting a boyfriend, etc. If only I could find a way to manage the curls and put it behind bars, I told myself, I would feel secure and sexy.I tried everything: rollers, hairspray, gels and, at one point, an iron.Then, in my second year, a miracle happened.I was asked to be a hair model for Japanese hair straightening, a process by which the molecules of my curls would be broken and reset in a bone-straight position.I was the perfect candidate, the hairdresser told me.Although they said how hair relaxing could damage the scalp , for the next five years I didn't find them to be true. All of the hairdresser's promises were fulfilled: With my hair straight and smooth, I was no longer the " mop". However, there was extreme damage done to my wallet. To keep up the straightening cost $ 700 every six months, and that was considered cheap. While some people thought I was crazy, I was willing to do anything to never again feel like that anxious, curly-headed girl in Grade 7.But when I moved out of my parents' house at age 26 and rented an apartment, the upkeep of my new image became too costly. I couldn't hide from my inner Medusa any longer.It was time to hug her and let her fly.Seeking a choice, I turned to the Internet, Google.After hours of searching, I hit upon a "curly haired" salon, a place designed for... Question: The best title of the passage can be_. Options: A: A Successful Stylist B: Road to Beauty C: My Medusa Hair D: Accept the Way We Are

I'm taking a test and have to guess the right answer to the question after the article. Article: The most popular names in the west Every year in Englishspeaking countries,people list the most popular names. Here are some examples. In the United States at the moment the three most popular names for girls are Emily,Emma and Madison. For boys,they are Michael,Joshua and Mathew. In Britain a parent today might call their little girl Grace,Jessica or Ruby. If they have a little boy they could call him Jack,Thomas or Oliver. In China names have very clear meanings. If a girl is called Mei,her name means "beautiful". If a boy is called Wu,his name means "like a soldier". Names in Englishspeaking countries are like this too. The girl's name Joy is probably partly chosen because the parents wish their daughter to be joyful and bring joy to others. If a girl is called Ruby,it may be because of the beautiful red precious stone. Parents often pick names that can be shortened. This can be confusing for Chinese people. Parents might choose such names because they want to be able to speak to their kid in a personal way. For example,a popular name is William. But William can be shortened to Will,Willy,Bill and Billy. The same is true of the favourite old name for a girl,Elizabeth. Elizabeth can be shortened to Beth,Liza and Liz. Another reason why kids get the names they do is that parents want to name their boy or girl after someone who is famous,such as an actor,a pop music star or a sports star. David is a popular name in Britain,partly because of the fame of the footballer David Beckham. Question: In Englishspeaking countries,parents often choose shortened names because they want to keep what they and their children talk about _ . Options: A: short B: quiet C: loud D: personal
