{{B}}Architecture{{/B}}
1 Architecture is to building as literature is to the printed word. The best buildings are often so well constructed that they outlast their original use. They then survive not only as beautiful objects, but as documents of the history of cultures. These achievements are never wholly the work of individuals. Architecture is a social art.
2 The renaissance brought about an entirely new age, not only in philosophy and literature but in the visual arts as well. In architecture, the principles and styles of ancient Greece and Rome were brought back to life and reinterpreted. They remain dominant until the 20th century.
3 Many kinds of stone are used as building materials. Stone and marble were chosen for important monuments because

Flying the Hypert Skies

A little airplane has given new meaning to the term "going hyper."
The Hyper-X recently broke the record for air-breathing jet planes when it traveled at a hypersonic speed of seven times the speed of sound. That’s about 5,000 miles per hour. At this speed, you’d get around the world -- flying along the equator -- in less than 5 hours.
The Hyper-X is an unmanned, experimental aircraft just 12 feet long. It achieves hypersonic speed using a special sort of engine known as a scramjet. It may sound like something from a comic book, but engineers have been experimenting with scramjets since the 1960s.
For an engine to burn fuel and produce energy, it needs oxygen. A jet engine, like those on passenger airplanes, gets oxygen from the air. A rocket engine typically goes faster but has to carry its own supply of oxygen. A scramjet engine goes as fast as a rocket, but it doesn’t have to carry its own oxygen
A. A jet engine that gets oxygen from the air.
B. A scramjet engine that doesn’t carry its own oxygen supply.
C. A rocket engine that carries its own supply of oxygen.
D. A jet engine that uses no oxygen.
