问题 The final quarter of the nineteenth century marked a turning point in the history of biology—biologists became less interested in applying an ideal of historical explanation deductively to organic function and more interested in discerning the causes of vital processes through experimental manipulation. But it is impossible to discuss the history of biology in the nineteenth century without emphasizing that those areas of biology most in the public eye had dependend on historical explanation. Wherever it was applied, historical explanation was deemed causal explanation The biologist-as-historian and the general historian of human events dealt with comparable phenomena and assumed necessarily a common mode of explanation
    Nineteenth-century biologists found a historical explanation of organic function attractive partly because their observation of the formation of a new cell from a preexisting cell seemed to confirm a historical explanation of cell generation. The same direct observation of continuous stages of development was also possible when they examined the complex sequence of events of embryogenesis. In both cases, the observer received a concrete impression that the daughter cell was brought into being, or caused, by the prior cell. The argument that these scientists employed confuses temporal succession and causal explanation, of course, but such confusion is the heart of most historical explanation.
    Not surprisingly, the evolutionary biologists of the nineteenth century encountered a particularly troublesome problem in their attempts to document historical explanation convincingly: the factual record of the history of life on earth (e. g. , that provided by fossils) was incomplete. The temporal continuity of living forms was convincing, but was an assumption that was difficult to uphold when one compared species or organisms forming any two stages of the evolutionary record. Nineteenth-century biologists recognized this problem and attempted to resolve it. Their solution today appears to be only verbal, but was then regarded as eminently causal. The fact of evolution demanded some connection between all reproducing individuals and the species that they compose, as well as between living species and their extinct ancestors. Their solution, the concept of heredity, seemed to fill in an admittedly deficient historical record and seemed to complete the argument for a historical explanation of evolutionary events.  [br] The primary purpose of the passage is to
选项 A、compare the information about organic function made available by historical explanation with that made available by the experimental investigation of living organisms
B、assess the influence that theories of history had on developments in the field of biology in the nineteenth century
C、discuss the importance of historical explanation in the thinking of nineteenth century biologists
D、contrast biologists’ use of historical explanation during the early nineteenth century with its use during the final quarter of the nineteenth century
E、evaluate the way in which the concept of heredity altered the use of historical explanation by nineteenth-century biologists
答案 C
解析 This question requires that we understand the fundamental purpose of the passage, which is a function of both its structure and content.
The first paragraph of the passage notes a turning point in the history of biology. In the late nineteenth century, biologists made a shift away from historical explanation of biology.
However, as the passage continues, it addresses the importance of historical explanation in biology throughout the nineteenth century.
A    The passage says little about the information about organic function that is made available by the experimental investigation of living organisms.
B    The passage focuses on historical explanation in biology. It does not discuss different theories of history. Therefore, it does not assess the influence of different theories of history on the influence on developments in biology.
C    Correct. The primary purpose of the passage is to discuss the importance of historical explanation in nineteenth-century biology.
D    The passage mentions the final quarter of the nineteenth century specifically to note the turning point when biologists began to use experimental manipulation as a way to discern the causes of vital processes. The passage does not contrast these biologists’ use of historical explanation during the final quarter of the nineteenth century with their use of it earlier in the nineteenth century.
E    The final sentence of the passage suggests that the concept of heredity seemed to complete the argument for a historical explanation of evolutionary events. However, this is just one part of the passage’s discussion of historical explanation in biology in the nineteenth century.
The correct answer is C.
