Article: Leonardo da Vinci's mother may have been a Chinese slave according to a new research by an Italian historian and novelist-Angelo Paratico, who has spent the last 20 years living and working in Hong Kong,researching the links between his homeland and China over the past half century. Mr. Paratico said the documents he has uncovered during two years of research form the basis of his latest book Leonardo Da Vinci, a Chinese scholar lost in Renaissance Italy. The book, which is due to be published next year, uncovers evidence that there's a link between Da Vinci and the Far Fast. Speaking to the South China Morning http://w|ww?.wln%100.com @Post, Mr. Paratico said, "I am sure that Leonardo's mother was from the East, but to make her a Chinese, we need to use a deductive method . One wealthy client of Leonardo's father had a slave called Caterina. After Leonardo's date of birth, she disappeared from the documents. She was no longer working there." It is believed that his mother was called Caterina, who, according to some reports, was a local peasant. But Mr. Paratico's new work claims it is most likely that Da Vinci's mother was a slave. Supporting his theory, he said, "During the Renaissance, countries like Italy and Spain were full of slaves from the East." He claimed that there were certain aspects of Da Vinci's life and works which suggest a Chinese link. For instance, he was writing with his left hand from left to right and he was also a vegetarian, which was not common. Mona Lisa is probably a portrait of his mother, as Sigmund Freud said in 1910. On the back of Mona Lisa, there is a Chinese landscape and even her face looks Chinese. Mr. Paratico said he believes the only way to solve the mystery is to dig out some of Da Vinci's relations in Florence and extract some DNA. Question: Mr. Paratico has stayed in Hong Kong for 20 years to _ . Options: A: study Da Vinci's mother B: explore the connection of Italy and China C: find Da Vinci's mother is a slave D: research China and Mona Lisa

Read the article and select the best answer. Article: Future historians will be in a particular position when they come to record the history of our own times. They will hardly know which facts to select from the great mass of evidence that's always increasing. What is more, they will not have to rely only oh the written word. Films, videos, CDs and CD-ROMs are just some of the huge amount of information they will have. They will be able, as it were, to see and hear us in action. But the historian attempting to show the distant past again is always faced with a difficult task. He has to make proper use of evidence available to draw reasonable conclusions. Good news is that even evidence that may appear unimportant can shed light on the history of early man. Up to now, historians have assumed that calendars came into being with the appearance of agriculture, for man of that time was faced with a real need to understand something about the seasons. Recent scientific evidence seems to suggest that this assumption is incorrect Historians have long been puzzled by dots, lines and symbols which have been carved on walls, bones and so on. The nomads who made these markings lived by hunting and fishing during the last Ice Age which began about 35,000 B.C. and ended about 10,000 B.C. By comparing and analyzing markings made in various parts of the world, historians have been able to read this difficult "language". They have found that it is connected with the passing of days and the stages of the moon. It is, in fact, a primitive type of calendar. It has long been known that the hunting scenes drawn on walls were not simply a form of expression of art. They had a certain meaning, for they were as near as early man could get to writing. It is possible that there is a certain relation between these, paintings and the markings that sometimes accompany them. It seems that man was making a real effort to understand the seasons 20,000 years earlier than has been supposed. Question: What's the Writer's purpose in writing this passage?
