D. To display their technological advancements.

[单项选择]Scientific tradition demands that scientific papers follow the formal progression :method first, results second, conclusion third. The rules permit no hint that, as often happens, the method was really made up as the scientist went along, or that accidental results determined the method, or that the scientist reached certain conclusions before the results were all in, or that he started out with certain conclusions, or that he started doing a different experiment. 　　Much scientific writing not only misrepresents the workings of science but also does a disservice to scientists themselves. By writing reports that make scientific investigations sound as unvarying and predictable as the sunrise, scientists tend to spread the curious notion that science is infallible. That many of them are unconscious of the effect they create does not alter the image in the popular mind. We hear time and again of the superiority of the "scientific method". In fact, the word "unscientific" has almost becom
A. require well worked-out methods in experiment.
B. ask for elimination of any accidental outcomes.
C. refuse inconformity of conclusions with results.
D. conflict with actual conditions as often as not.
