[简答题]

There is probably no limit to what science can do in the way of increasing positive ex cellence.Health has already been greatly improved; in spite of the lamentations of those who idealize the past, we live longer and have fewer illnesses than any class or na tion in the eighteenth century.
With a little more application of the knowledge we already possess, we might be much healthier than we are. And future discoveries are likely to accelerate this process enormously.
So far, it has been physicai science that has had the most effect upon our lives, but in the future physiology and psychology are likely to be far more potent. When we have discovered how character depends upon physiological conditions, we shall be able, if we choose, to produce far more of the type of human beings that we admire. Intelligence, ar tistic capacity, benevolence—all these things no doubt could be increased by science. There seems scarcely any limit to what could be c

[单项选择]A study of art history might be a good way to learn more about a culture than is possible to learn in general history classes. Most typical history courses concentrate on politics, economics, and war. But art history focuses on much more than this because art reflects not only the political values of a people, but also religious beliefs, emotions, and psychology. In addition, information about the daily activities of our ancestors—or of people very different from our own—can be provided by art. In short, art expresses the essential qualities of a time and a place, and a study of it clearly offers us a deeper understanding than can be found in most history books. In history books, objective information about the political life of a country is presented; that is, facts about politics are given, but opinions are not expressed. Art, on the other hand, is subjective: it reflects emotions and opinions. The great Spanish painter Francisco Goya was perhaps the first truly "political" artist. In his well-known painting The Third of May, 1808, he criticized the Spanish government for its misuse of power over people. Over a hundred years later, symbolic images were used in Pablo Picasso"s Guernica to express the horror of war. Meanwhile, on another continent, the powerful paintings of Diego Rivera, Jose Clemente Orozco, and David Alfaro Siqueiros-as well as the works of Alfredo Ramos Martinez-depicted these Mexican artists" deep anger and sadness about social problems. In the same way, art can reflect a culture"s religious beliefs. For hundreds of years in Europe, religious art was almost the only type of art that existed. Churches and other religious buildings were filled with paintings that depicted people and stories from the Bible. Al though most people couldn"t read, they could still understand biblical stories in the pictures on church walls. By contrast, one of the main characteristics of art in the Middle East was (and still is) its absence of human and animal images. This reflects the Islamic belief that statues are unholy.The passage mainly discusses ______.
A. the difference between general history and art history
B. the making of art history
C. what we can learn from art
D. the influence of artists on art history
