Article: As a young adult, Noah Webster was a teacher. At this time, the colonies were fighting for independence from Britain. Yet the books that American children used in school all came from Britain. The books were all about British people and British places. Webster wanted books that would mean more to American children. So he wrote three books that used American examples -- a grammar book, a spelling book, and a reader. These books were very popular, and millions of them were sold. Webster was interested in changing the spellings of words. He wanted words to be spelled the way they were pronounced. For example, he thought the word "head" should be spelled "hed", and the word "laugh" should be spelled "laf". People liked Webster's suggestions. However, few words were actually changed. One group of words that were changed were words in which an unpronounced "u" followed an "o". That is why Americans write "color" and "labor", and the British write "colour" and "labour". With the money he made from his books, Webster was able to write. It was the first American English dictionary, published in 1828. Webster's dictionary had over 70000 words and gave the meaning and origin of each. To this day, Webster's work is the example that most dictionaries of American English follow.
Question: Which of the following statements is right?
Options: (A) Noah Webster had to borrow books from Britain when he was a student. (B) Noah Webster had his own government when he was very young. (C) When Noah Webster taught at schools, he wrote some story books. (D) As a teacher, Noah Webster wasn't satisfied with the books he used.

Article: You can have your adventure and eat too at Europe's first green restaurant where traditional German food is served in a beautifully lit wooden hilltop restaurant powered by solar energy at a height of 1,025 metres among tall trees in the Black Forest. The Rappenecker Hutte is a 350-year-old farm house in south Germany which has been serving as a hikers' restaurant for several years. It was the starting point of the downhill course of the Mountain Bike World Championship (MBWC) in 1995 and is a well-known station of the Black Forest Ultra Bike Marathon (BFUBM). "People come here for adventure trips, mountain biking or hiking and stop for traditional German food. We produce all our energy from renewable sources as it is very expensive to get a power grid connection at this site," said Dirk Behringer, owner of the Rappenecker Hutte. Like the restaurant, the story of its present owner is equally amazing as Behringer, 57, left his well-paid job in 2003 to stay here with his wife. "I have traveled across the world and as I was growing old I realized I wanted to retire and live in nature. So I rented the restaurant. Since then I, along with my wife, live here in summer and we travel during winter," said the six-foot-tall man dressed in a T-shirt and shorts. Due to heavy snow during winter, the restaurant opens only for six months from April to September when it receives around 500 guests per week. The Behringer couple has employed no helper and does everything from cooking to cleaning at this hilltop restaurant which gives a picturesque view of the Black Forest. There are not many dishes on the menu for unexpected visitors. On a routine basis, there is one vegetarian dish which includes fried potatoes with dense milk cream, boiled vegetables and fresh salad. The non-vegetarian dish includes fried potatoes with pork and salad. There are also options to pick from fresh juices, hard drinks and coffee. All vegetables, fruits, dairy products and meat supplies to the restaurant come from farms in nearby villages.
Question: By mentioning such events as MBWC and BFUBM, the author intends to _ .
Options: (A) prove the restaurant has a long history (B) advise us to do more exercise (C) stress the restaurant's being unusual (D) express his fondness of the restaurant

Article: Sixteen years ago I learned this lesson. And I learned it in the back of a New York City taxi cab. Here's what happened. I got in a taxi, and we took off for Grand Central Station. We were driving in the right lane when all of a sudden, a black car jumped out of a parking space right in front of us. My taxi driver used his brakes , the tires made a loud noise, and at the very last moment our car stopped just one inch from the back of the other car. I couldn't believe it. But then I couldn't believe what happened next. The driver of the other car, the guy who almost caused a big accident, turned his head around and he started yelling bad words at us. I couldn't believe it! And this is when my taxi driver told me what I now call: "The Law of the Garbage Truck ." He said: But then here's what really blew me away. My taxi driver just smiled and waved at the guy. So, I said: "Why did you just do that? This guy could have killed us! "Many people are like garbage trucks. They run around full of garbage, full of frustration, full of anger, and full of disappointment. As their garbage piles up, they look for a place to dump it. And if you let them, they'll dump it on you."So one day when someone wants to dump on you, don't take it personally. Just smile, wave, wish them well, and move on. Believe me. You'll be happier." So I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and spread it to other people at work, at home, or on the street? It was then that I said: "I don't want their garbage and I'm not going to spread it anymore." I began to see Garbage Trucks. I see the load people are carrying. I see them coming to dump it. And like my taxi driver, I don't take it personally. I just smile, wave, wish them well, and I move on.
