Paper was first created about 2,000 years ago in China.After its invention, people started to write on paper to make books.In those days, books were only produced one at a time② by hand③.As a result, there were not many books, and they were expensive.So, few people had the chance to learn to read.
Printing was invented in China during the Sui and Tang Dynasties.Later, developments in printing made it possible to④ produce books more quickly and cheaply.A trade in books resulted, and more people learnt to read.Knowledge and ideas spread faster than ever before. In a way⑤, we can compare the invention of paper and printing to the introduction of the Internet in the twentieth century.
Although the Internet is still young, it is growing very fast, and may become more powerful than printing. A much larger amount of⑥ information can be stored in more varied forms on the Internet than in books.Someone with an Internet connection can find information much more easily than they can find it in printed forms.And the machines we use to read it are now small and light, often smaller and lighter than a single book.
Computers and the Internet are used in classrooms now, and newspapers and magazines are already read online.So what direction will traditional printing take in the future Will books be replaced by the Internet Let’s wait and see.

A.回答问题
请阅读下面这篇文章,根据所提供的信息,回答5个问题,要求所写答案语法正确、语义完整切题。
Compass, paper-making skill, gunpowder and typography are the Four Great Inventions in ancient China.
Compass
The idea of inventing the compass first came from the ancient Chinese labor people. They found the magnet (磁铁) could point to direction when they worked. The compass played an important role in the navigation (航海) after it was introduced to Europe.
Paper-making skill
Cai Lun improved the paper-making skill in the Eastern Han Dynasty (105AD). He made the vegetable fiber paper with the covering of a tree, broken fishing network, cloth, and so on. From then on, paper has become the main material that is generally used to write.
Gunpowder
It was first invented by accident while masters were trying to make medicine that made people live for long. In the end of Tang Dynasty, the gunpowder began to be used in the army (军队).
Typography
Before printing was invented, people had to depend on handwriting to reproduce a book. It was very slow and had many mistakes. Wood-block printing first appeared in the early Tang Dynasty. Later in about the 4th century, the method of rubbing a piece of paper on an engraved (被雕刻的) stone covered with ink was used to make copies. Wood-block printing was not very convenient. To change this disadvantage, Bi Sheng invented the movable type.
