问题     According to von Kárman, a scientist seeks to understand what is; an engineer, to create what never. But dichotomies are seldom clear-cut. When a scientist proposes a truly new hypothesis about, say, the origin of the universe, that hypothesis “never was” prior to its articulation by that scientist. Einstein, certainly a prototypical scientist, took that view, criticizing physicist and philosopher Ernst Mach for having “thought that somehow theories arise by means of discovery rather than invention.” Science historian Thomas P. Hughes notes that to Einstein, invention was the manipulation not only of things but also of concepts. Einstein believed that an artifact was a materialized concept and that a hard-and-fast line between technology and science simply did not exist.
The primary purpose of the passage is to
选项 A、suggest that a certain term is often misunderstood
B、question the basis for a particular distinction
C、show how one field has been influenced by another
D、argue that one view of a dichotomy has changed over time
E、examine the origins of a scientific theory
答案B
解析 本文首句认为科学和工程之间存在区别，第二句反驳了这一观点，后面句子均和这句话顺承，因此本文是驳论文，选项B正确。A项文中未提及。C项这两个领域可以认为分别指的是科学和技术，但是文章说这两个领域没有界限，并不等于一个领域影响另一个。D项文中未提及。E项文中未提及。
