Input: Consider Input: Article: The English language is the result of the invasion of the island of Britain over many hundreds of years.The first invasions were by a people called Angles about 1, 500 years ago. The Angles were a German tribe who crossed the English Channel . Later two more groups crossed to Britain. They were the Saxons and the Jutes. Through many years, the Saxons, Angles and the Jutes mixed their different languages. The result is what is called Anglo-Saxon or old English. The next great invasion of Britain was done by Vikings about 1, 100 years ago. Many English words used today come from these ancient Vikings. The next invasion of Britain took place more than 900 years ago, in 1066. History experts call this invasion the Norman Conquest. The Normans were a French-speaking people from Normandy in the north of France. These new rulers spoke only French for several hundred years. It was the most important language in the world at that time. It was the language of educated people. But the common people of Britain still spoke old English. Old English took many words from the Norman French. Some of these include "damage", "prison", and "marriage". The French language used by the Norman rulers greatly changed the way English was spoken 800 years ago. English became what language experts call Middle English. Middle English sounds like Modern English. But it is difficult to understand now. The history of the English language continues as Middle English becomes Modern English, which is spoken today.
Answer: The Angles.

Output: Who was the first invaders of Britain?

Input: Consider Input: Article: Among all the fast growing science and technology, the research of human genes , or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people. The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by _ s. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied , not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span can be prolonged. Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it and a healthy child will be born. Some people are worrying that the gene research can be used to manufacture (produce) human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
Answer: Expressing the writer's idea that gene technology will benefit people

Output: What is the main purpose of writing this passage?

Input: Consider Input: Article: Are you a big fan of pirate stories? Do you know how to talk like a pirate? You can have fun on September 19th. This special holiday is called International Talk Like A Pirate Day. It was invented in 1995 by two young Americans, John Baur and Mark Summers. These two good friends came up with this idea when they were playing racquetball, and began to talk like pirates. At that moment, they thought, "Young people are interested in pirate, but there is no such a chance for people to get together to share it. Why not have a day when everybody talks like a pirate?" They decided to make September 19th the date. Since then, Baur and Summers have tried hard to promote Talk Like A Pirate Day. As Baur said, "We've talked like pirates, and encouraged several of our friends to do so every September 19th." At first, this day was only known by a few people. In 2002, Baur and Summers sent a letter about their invented holiday to Dave Barry. This columnist really liked their idea. He promoted the holiday and made it known to more and more people. Now, it has really become an international holiday. On Talk Like A Pirate Day, you need to dress like a pirate. You should wear a big hat or maybe cover one of your eyes. You can pretend to be any kind of pirate that you can find in any story or movie. Having fun and being relaxed are not the only best things about the holiday. Young people share the same interest and childhood dreams that day. That's why it is welcomed by so many people, especially young people. Unlike traditional holidays, International Talk Like A Pirate Day is a brand new holiday which is invented by the youth themselves and celebrated by themselves too. Because of Baur and Summers' imagination and creativity, thousands of young people's pirate dream come true. Next time, when you have a good idea, why not share it with your fiends and insist on your belief? Maybe you can create another wonderful holiday for the youth in the future.
