Article: The famous car Rolls-Royce has been largely hand-made and always one of the most expensive cars on the market. In fact, Rolls-Royce is made up of two men's names, Charles S. Rolls and Henry Royce. They came from very different backgrounds, received very different educations and when they met; their careers were going in very different directions. In 1903, Royce bought a second-hand France Decauville car. He found the car unreliable, difficult to start and overheated. Royce decided he could do better himself and set about building two-cylinder car of his own design. The first of these, built almost completely by Royce himself, was a success in almost every way: it started easily, ran smoothly and was very reliable. It never failed to impress everyone who saw it rode in the car, including Rolls. While he was a university student at Cambridge, Rolls acquired a French Peugeot. It was the first automobile seen at Cambridge and by the time Rolls finished his studies, he was probably the most skilled driver in Britain. In 1902, Rolls went into the business of selling cars and became a leading automobile . He was looking for a British car to market when he was told that Henry Royce had designed and built a two-cylinder automobile. In 1904, Royce and Rolls joined together to build and sell motor car.

Over the years the automaker built a legendary reputation.

Article: On the first day of class, Mr. Whiteson gave us a lecture about a creature called cattytiger, a kind of cat-like animal that completely disappeared during the Ice Age. He passed round a skull as he talked, and we all felt interested and took notes while listening. Later, we had a test about that. When he returned my paper, I was very, very surprised. There was a very large cross through each of my answers. And so it was with everyone else's in our class. What had happened? Everyone was wondering and couldn't wait to get the answer. Very simple, Mr. Whiteson explained. He had made up all that story about the cattytiger. There had never been such an animal. So why none of us noticed that and how could we expect good marks for the incorrect answers? Needless to say, we got very angry. What kind of teacher was this? We should have guessed it out, Mr. Whiteson said. After all, at the very moment he was passing around the cattytiger skull (in fact, a cat's), hadn't he been telling us that it completely disappeared during the Ice Age? Clearly he was telling a lie. But we just kept busy making notes and none used his head. We should learn something from this. Teachers and textbooks are not always correct.
