问题     There is currently abroad a new wave of appreciation for breadth of knowledge. Curricula at universalities and colleges and programs in federal agencies extol(赞扬)the virtues of a broad education. For scientists who work in specialized jobs, it is a pleasure to escape in our spare time to read broadly in fields distant from our own. Some of us have made interdisciplinary study in our occupation, which is no surprise, because much of the intellectual action in our society today lies at the interfaces between traditional disciplines. Environmental science is a good example, because it frequently requires us to be conversant in several different sciences and even some unscientific fields.
    Experiencing this breadth of knowledge is stimulating, but so is delving deeply into a subject. Both are wonderful experiences that are complementary practical and aesthetic(美学的)ways. They are like viewing the marvelous sculpture of knowledge in two different ways. Look at the sculpture from one perspective and you see the piece in its entirety, how its components connect to give it form, balance, and symmetry. From another viewpoint you see its detail, depth, and mass. There is no need to choose between these two perspectives in art. To do so would subtract from the totality of the figure.
    So it is with science. Sometimes we gaze through a subject and are reluctant to stop for too much detail. As chemists, we are fascinated by computer sciences or molecular genetics, but not enough to become an expert. Or we may be interested in an analytical technique but not enough to stay at its cutting edge. At other times, we become immersed in the detail of a subject and see its beauty in an entirely different way than when we browse. It is as if we penetrate the surface of the sculpture and pass through the crystal structure to the molecular level where the code for the entire structure is revealed.
    Unfortunately, in our zeal for breadth or depth, we often feel that it is necessary to diminish the value of the other. Specialists are sometimes ridiculed with names such as "nerd" or "technocrats", generalists are often criticized for being too "soft" or knowing too little about any one thing. Both are ludicrous(可笑的)accusations that deny a part of the reality of environmental science. Let us not be divided by our passion for depth or breadth. The beauty that awaits us on either route is too precious to stifle, too wonderful to diminish by bickering(争吵).
The commentator would say that the totality of the sculpture of knowledge______.
选项 A、is mainly composed of two elements
B、presents two different points of view
C、cannot be perceived from one perspective
D、is a whole made up of complementary elements
答案D
解析 细节题。此题根据题干中的关键词“the totality of the sculpture of knowledge”可以定位在文章第二段。本段第三句话提到：这就如同用两种不同的方法观察伟大的雕塑。这说明例证关系的“证”应该在前面，即本段的第一、二句话，其大意是：体验知识的广度很刺激，但是深度探索一个物体同样刺激。这两种美妙的体验是实用和美学两种方式的互补。故选项D正确。
