Read the following article and select the best answer. Article: Raeann Sleith began making bracelets when she was six. Family and friends loved her designs and asked for more. When admirers suggested that Raeann sell her bracelets, she realized she wanted to do just that -- and donate the money to help kids with special needs, like her brother Derek. Raeann's older brother, Derek, has cri du chat syndrome. Children with cri du chat usually have problems understanding ideas and might have a hard time learning to talk. Many also have weak muscles that can cause problems with walking or using their fingers to pick things up. The term cri du chat means "cry of the cat" in French. Babies with cri du chat often have a high-pitched cry that sounds like that of a little cat. Over the years, Derek's teachers helped him learn sign language and gestures. They also taught him skills such as recognizing letters, cutting with scissors, and understanding basic math. Raeann wanted to donate money to Derek's school. "I just wanted to help my brother," she says, "and the people who help him." At first, Raeann focused on creating jewelry that would raise awareness for cri du chat. But people started requesting bracelets to wear as a symbol of support and awareness for a variety of other diseases and disorders. To create those symbols, Raeann researched the color most often associated with raising awareness for the disease or disorder, such as pink for breast cancer or orange for leukemia. In the end, it turned out to be a great idea. In only a few years, Raeann has donated more than $30,000 to local charities. Raeann's mom says that working on the bracelets has developed the generosity and kindness that already existed in her daughter. Raeann plans to keep making bracelets and raising dollars for charities. "I just want to keep going on with it," she says, "to help my brother more." Question: The bracelets Raeann Sleith has made _ . - are decorated with colorful jewels - represent different kinds of diseases - are very popular all over the world - add up to more than 30,000
represent different kinds of diseases

Read the following article and select the best answer. Article: Billie Holiday was one of the greatest jazz singers in America. Her life was just a mixture of success and tragedy . Her singing expressed her experiences and feelings. Billie Holiday's parents Sadie Fagan and Clarence Holiday were young when their daughter was born. Their marriage failed because Clarence Holiday was often out. He traveled as a musician with some of the earliest jazz bands and inspired his daughter. Sadie cleaned people's houses to make a living. Later she moved to New York City where the pay was higher, for which she had to send her daughter to one of her s. The young girl changed her name to Billie, because she liked a movie star, Billie Dove. The talented Billie Holiday loved singing. She sang and listened to music whenever she could. In one place near her home there was a machine that played records. The building was a theater where many famous singers also performed their newly-made songs for free. Billie cleaned floors and did other jobs for the theater so that she could listen to the records. It was there that young Billie first heard the records of some famous black American blues artists of the 1920s. She heard Bessie Smith sing the blues. And she heard Louis Armstrong play the horn. Both musicians had a great influence on her. Billie Holiday once said, "I do not think I'm just singing. I feel like I am singing the song from my heart. What comes out is what I feel." Question: Billie Holiday's parents' marriage ended because _ . - Sadie moved to New York City - the family couldn't support itself - Clarence spent too much time in working - Clarence was a strange person
Clarence spent too much time in working

Q: Read the following article and select the best answer. Article: I still remember the days when I was a youthful student in an engineering school. I lived a casual life, without caring about the future. I smoked, drank with friends and made girl friends. Little did I realize that casualness would certainly lead to loss. Two years had passed and I was staring down a report card that highlighted FAIL in more than half the subjects. I didn't care, at least not till my dad found out about it. You see, I studied in India and unlike the United States where the students are expected to finance their own education, my dad financed me. Then came the day when my dad found out my habit of smoking. He lost his temper but he just told me, "Son, your allowance is cut in half from this moment on". It hit me like a roundhouse kick from Bruce Lee. I was jolted out of my bones! I couldn't comprehend how to pay off the debts that I had accumulated in college. I owed everybody money: the grocery store, the bars, the restaurants, my friends, etc. I was living a life filled with credit. When I went back to college, I knew that if I don't change the way I live my life I won't be able to pay everybody off. So I decided to make some changes, drastic changes. I quit smoking, cut off from my friends who led me down the wrong road, starting hanging out in libraries and reading my engineering books. One year later, I went from a miserable failure to a magna cum laude . . This incident made me know that anything is possible if you take action and do something about it, however small or large. Even today it still motivates me when I feel that I'm about to lose or give up. It reminds me that I can do it! Question: The author didn't care about his study until _ . - he entered the engineering school - he was in heavy debt he couldn't bear - he decided to give up smoking - his allowance was cut in half
A: his allowance was cut in half

(Question)
Read the following article and select the best answer. Article: At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it's sunny and brighten when a passing cloud blocks the sun. A wall of windows at a University of Pennsylvania engineering building has built-in blinds controlled by a computer program that follows the sun's path. Buildings are getting smarter and the next generation of building materials is expected to do even more. Windows could catch the sun's energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up. Many new materials and technology have been designed in the last 15 years. They are now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like "green roofs", where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out. As technologies such as sensors become cheaper, their uses spread. The elevators at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light. More new building materials and technology are in development. A Philadelphia building firm is now working on "smart wrap" that uses tiny solar collectors to catch the sun's energy and transmitters as wide as a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so. Question: _ will be developed and used in the construction industry. - "Green roofs" that cool or heat buildings - "Smart wrap" that catches the sun's energy - Sunlight-measuring sensors that control lights - Window coating that lets light in, but keeps heat out
(Answer)
"Smart wrap" that catches the sun's energy
