[Q]: Article: This morning, a Virgin Atantin 747 Jumbo Jet became the first commercial airplane to fly on biofuel. The short flight from London to Amsterdam used a blend of 20% babassu oil mixed with 80% conventional jet fuel. What was really exciting about the flight was the fact that the engine did not have to be altered in any way for the biofuel to work While this is a great initial step in trying to reduce CO2(carbon-dioxide)emissions from airplanes. there are a lot of hurdles that still need to be overcome. First and foremost, unlike the normal fuel used to run airplanes (known as Jet A),biofuel freezes at high altitudes. Also, Jet'A'fuel burns consistently (at the same pace),which means it provides a safe and reliable fuel for long flights--engineers are not sure if biofuel will be able to do the same. The biggest hurdle to a full biofuel switch is our ability to be able to grow enough crops that can be converted to biofuel. There are two concerns that scientists have in this matter - the first is that the land to grow the extra crops will come from clearing more of our forests and the second is that since it competes with what we eat, the price of food will go up. However, Richard Branson of Virgin Airlines, envisions that if biofuel starts to replace oil on a greater basis, it will be manufactured from algae produced in sewage treatment plants, not from food sources. Birgin Airlines is not the only one trying to look for alternative fuel sources. Earlier this year, an Airbus A380 used another alternative fuel-a man-made mix of gas-to-liquid, in one of its four engines. The flight was tested by Rolls Royce (manufacturer of jet engines), in partnership with Shell (an oil company). Rolls Royce is also working with Air New Zealand on a similar project. While a complete switch to alternative fuel may take years, it is very encouraging to see airlines, oil companies and airplane manufacturers all coming together to try to make it happen!
Question: .Why does Virgin Airlines try to replace normal fuel with biofuel?
Options: (A) To cut down the flight cost of the company. (B) To remove some hurdles for the biofuel to work. (C) To reduce CO
2 emissions from airplanes. (D) To test plane engines on biofuel.

[Q]: Article: When my daughter, Sophie, was admitted to a college we were very happy, but a little worried about becoming empty nesters. I knew I had to do something to help myself adapt, starting with the summer before she left. Sophie had a pack of colorful T-shirts. I knew she wouldn't wear them any more, so I decided to make a quilt out of them for her bed at college. It focused my energy, and also let me relive some memories. I tried to work on the quilt when Sophie wasn't at home----which turned out to be often. She was very busy with her friends. Even when she was around, her door was shut more than usual. I felt a bit hurt. After all, we didn't have much time together before she went to college, I was already missing her, and she hadn't ever left yet. When we arrived at the college, a wave of emotion flooded me. I tried to hold it back, but Sophie saw it in my face. She took a big red book from her bag. "I made this for you, Mom," she said. Then I knew why she had been staying behind a closed door that summer. It was an album of photographs documenting the life of our family over the last 17 years. I broke into tears. Some of it was sadness at having to let her go, but some of it was joy. I knew that our connection was more powerful than ever, and that we'd always be connected by the strongest of threads, the love that went into every stitch of her quilt and every photo of my album. In Sophie's dormitory I unfolded the quilt on her bed. For a moment she was speechless. Then she threw her arms around me. "Mom, I love you," she said. One of her new friends was calling her outside. Sophie turned, and I let her go.
Question: What do we learn about Sophie from the passage?
Options: (A) She did not understand how her mother felt about her leaving. (B) She had few friends, and kept to herself at home that summer. (C) She made a photo album to show her love. (D) She liked her colorful T-shirts very much.

[Q]: Article: Tayka Hotel De Sal Where: Tahua, Bolivia How much: About $95 a night Why it's cool: You've stayed at hotels made of brick or wood, but salt? That's something few can claim. Tayka Hotel de Sal is made totally of salt -- including the beds (though you'll sleep on regular mattresses and blankets). The hotel sits on the Salar de Uyuni, a prehistoric dried-up lake that's the world's biggest salt flat. Builders use the salt from the 4,633-square-mile flat to make the bricks, and glue them together with a paste of wet salt that hardens when it dries. When rain starts to dissolve the hotel, the owners just mix up more salt paste to strengthen the bricks. Green Magic Nature Resort Where: Vythiri, India How much: About $240 a night Why it's cool: Riding a pulley -operated lift 86 feet to your treetop room is just the start of your adventure. As you look out of your open window -- there is no glass! -- you watch monkeys and birds in the rain forest canopy. Later you might test your fear of heights by crossing the handmade rope bridge to the main part of the hotel, or just sit on your bamboo bed and read. You don't even have to come down for breakfast -- the hotel will send it up on the pulley-drawn "elevator". Dog Bark Park Inn B&B Where: Cottonwood, Idaho How much: $92 a night Why it's cool: This doghouse isn't just for the family pet. Sweet Willy is a 30-foot-tall dog with guest rooms in his belly. Climb the wooden stairs beside his hind leg to enter the door in his side. You can relax in the main bedroom, go up a few steps to the loft in Willy's head, or hang out inside his nose. Although you have a full private bathroom in your quarters, there is also a toilet in the 12-foot-tall fire hydrant outside. Gamirasu Cave Hotel Where: Ayvali, Turkey How much: Between $130 and $475 a night. Why it's cool: This is caveman cool! Experience what it was like 5,000 years ago, when people lived in these mountain caves formed by volcanic ash. But your stay will be much more modern. Bathrooms and electricity provide what you expect from a modern hotel, and the white volcanic ash, called tufa, keeps the rooms cool, about 65degFin summer. (Don't worry -- there is heat in winter.)
