Article: Andy Steele lives just a few blocks from the campus of Black Hills State University in Spearfish, S.D., so commuting to class isn't the problem. But he doesn't like lectures much, isn't a morning person, and wants time during the day to restore motorcycles. So Steele, a full-time senior business major, has been taking as many classes as he can from the South Dakota State system's online offerings. He gets better grades and learns more, he says, and insists he isn't missing out on the college experience. "I still know a lot of people from my first two years living on campus, and I still meet a lot of people," he says. But now, he sets his own schedule. At least 2.3 million people took some kind of online courses, according to a recent survey by The Sloan Consortium, an online education group, and two-thirds of colleges offering "face-to-face" courses also offer online ones. But what were once two different types of classes are looking more and more alike and often falling into the same pool of students. At some schools, online courses originally intended for non-traditional students living far from campus have proved surprisingly popular with on-campus students. A recent study found 42 percent of the students enrolled in its distance education courses were located on campus at the university that was hosting the online courses. Numbers vary depending on the policies of particular colleges, but other schools also have students mixing and matching online and "face-to-face" credits. Motives range from lifestyle to adapting a job schedule to getting into high--demand courses. Washington State had about 325 on-campus undergraduates taking one or more distance courses last year. As many as 9,000 students took both distance and in-person classes at Arizona State last year. "Business is really about providing choices to their customers, and that's really what we want to do," said Sheila Aaker, extended services coordinator at Black Hills State. Many schools, such as Washington State and Arizona State, let departments and academic units decide who can take an online course. They say students with legitimate academic needs a conflict with another class, a course they need to graduate that isfull--oftenget permission, though they still must take some key classes in person.
Question: What is the purpose of the passage?
Options: (A) To introduce Steele to us, who prefers online courses. (B) To tell us about the development of campus courses. (C) To show the differences between campus courses and online courses. (D) To show more on-campus students are taking online courses.

Article: A teddy bear from Cumbria is launching into space to raise cash for charity . Terence, an experienced traveller who has been to Iraq, will be the guest of honour on aviation legend Burt Rutan's Spaceship One when it flies above Earth. The mission takes off from California on September 29, and on his return the cuddly toy will be auctioned off in aid of the North Air Ambulance Appeal . Spaceship One is the world's first private spacecraft, and is competing for a prestigious space travel prize. Chief executive of the Great North Air Ambulance Service (GNAAS), Graham Pickering, said "flying officer" Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since. He said, "Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft, trying parachuting and even looking drunk and disorderly. When the RAF finally discharge him he will be a very rare bear indeed--we just hope he does not burn up on re-entry to Earth." GNAAS, which needs charitable donations of more than PS2m a year, has three air ambulances . Peter Bond, spokesman for the Royal Astronomical Society, said Terence's safety was not guaranteed. He said, "This is a new and experimental craft and this will only be the second time it has flown. During its first voyage it developed technical problems but hopefully they have now been resolved." Since May, Terence has spent time with members of 100 Squadron based at RAF Leeming in Basra, Iraq, and at air shows with performing fighter planes. Spaceship One will fly 100km (62 miles) above the Earth's surface, just breaking through the planet's atmosphere. If it repeats the feat inside two weeks, it will claim the $10m Ansari X-Prize set up to encourage the private space flight business.
Question: Terence is _ .
Options: (A) a real bear living in England (B) an experienced astronaut (C) an air force officer (D) a toy bear

Article: Nowadays, most of us live a busy life. What do you do to keep yourself relaxed? Besides spending time with family, having a glass of wine with friends or reading a book, how about a hobby? Personally, I'm a collector. I like blue and white pieces the best---blue and white anything!Plates,jars,vases, cups, bowls---I love them all. Collecting items is like something you can't get enough of. You get one, and you want to have more. I find collecting to be a fun and inspirational hobby. In many ways, it's like a puzzle I'm never tired of solving. I look high and low for new pieces to add to my collection. I can often be found visiting Marshell's, looking over their inexpensive offerings. In fact, I found one of my favorite pieces there. I've mixed inexpensive pieces from Marshell's with more expensive finds. A lot of times, it's the piece I'm not looking for that falls into my lap; I find a way to make it part of my blue and white family. What I love about my collection is that when I get inspired, I can move them around the house, mix and match and make things look fresh and new. Ever since I was a little girl, blue has been my favorite color1. I think I got it from my aunt in Mexico. Some of my earliest memories are visiting her in Mexico and sitting on a chair in her kitchen, which had blue and white tiles from the floor to the ceiling. I would spend countless hours admiring all the beautiful blue and white plates and shiny blue tiles around her kitchen. Once I had a home, I began to build my own blue and white collection.
