Q: Read the following article and select the best answer. Article: A 13-year-old boy traveled to Washington, D.C. to raise money for homeless kids. Zach Bonner was pretty tired. Instead of going to camp last summer, Zach decided to walk 668 miles from Atlanta to Washington, D.C. He hoped more people would help homeless kids. His journey to help others began six years ago. Zach walked from his home in Tampa to Tallahassee. Then, in 2008, Zach Bonner went on a 270-mile walk from Tallahassee to Atlanta. In 2010, he did it again, from Tampa to Los Angeles. Last summer, Zach traveled 12 miles every day on foot. Along the way, he collected more than 1000 letters about homeless children. He hoped to give the letters to President Obama. Zach says he wants his walk to make a difference. More than 1 million children in the U.S. have nowhere to live. During his journey, Zach spent 24 hours with some homeless children so he could learn the difficulties they face. When Zach walked the last mile of his long journey, more than 500 supporters, including 300 homeless kids, joined Zach. They went with him down the National Mall. "It was a long walk," Zach says, "but it was meaningful." Although the journey is difficult and tiring, Zach won't give up. "When homeless kids get tired of being homeless, they don't get to stop. So why should I stop when I get tired of walking?" Question: Last summer, Zach Bonner _ . - went to camp - learnt to face difficulties - wrote letters to President Obama - walked from Atlanta to Washington
A: walked from Atlanta to Washington

Q: Read the following article and select the best answer. Article: Think stars don't move? Think again! When you look at the sky at night, the stars may appear to stay in the same place. But stars are always on the move--they are just so far away that the movement is hard to see. But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities . It was located on the outer edge of the Milky Way, the galaxy we live in. The star was speeding away like nothing he'd ever seen. "It seemed unbelievable. No star in the galaxy has a speed like that," Brown remembers. "I thought, oh my goodness, I have something kind of special here." No one had ever seen a star like this one. What does a scientist do when the results don't make sense? Brown didn't give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called _ stars. Hyper means "above" and velocity has to do with speed. He and his team just found six more of these "above speed" stars, bringing to the total of 16. And, he says, he's found even more, and is just waiting for the scientific community to confirm them. Question: Which of the following is TRUE? - Stars never move at all. - No star in the galaxy has a fast speed. - It's hard to see the stars moving. - Brown has never seen something special.
A: It's hard to see the stars moving.

Q: Read the following article and select the best answer. Article: Fashion always keeps at least one eye on the future. Now scientists are lending a hand, developing tomorrow's super-powered clothing such as coats that can recharge your MP3 player and make you stronger. For example, electronics could get recharged in the future simply by plugging them into your outer wear, because Australian researchers are designing clothing that can collect energy from a person. The coats would include small things that change vibration energy from a person's movements into electricity. High-tech fabrics would carry this energy to batteries . "It will look like an ordinary(common)coat but have super energy," said Adam Best, an Australian head research scientist. " _ has important uses for soldiers in the field and could mean they no longer need to carry heavy batteries,'' Best added. "Above all, they'd be wearing the battery, not carrying it." Besides helping soldiers, these coats could also have common uses for common people, such as powering radios, mobile phones, MP3 players or medical things. Solar-powered handbags could do the same thing. Thanks to self-cleaning fabrics developed by scientists working for the U. S. Air Force, underwear and sports clothing could go weeks without washing. The general idea of clothes that never get dirty can be found in the 1951 film The Man in the White Suit. The new technology helps keep off water, oil and bacteria . High-tech fabrics could also help serve as protection. For example, future fabrics could lead to soft helmets that turn hard in an accident. Not all the possible fabrics of tomorrow are necessarily high-tech. For example, chicken feathers and other things of the farming industry could get changed into wool-like fabrics or cotton-like ones, helping use fewer fabrics made from oil. Scientific development is also creating wool that doesn't become bigger or smaller after washing. And future clothing could help soldiers shoulder heavy bags and help people walk. But not all electronic coats have such uses--some might serve as video game... Question: Which of the following is TRUE according to the article? - You can get electronic energy from your clothes in the future. - Self-cleaning coats are developed for American scientists. - We will no longer use fabrics made from oil in the future. - The future high-tech clothing will be used only for soldiers.
A: You can get electronic energy from your clothes in the future.
