问题 A vast health checkup is now being conducted in the western Swedish province of Farmland with the use of an automated apparatus for high-speed multiple-blood analyses. Developed by two brothers, the apparatus can process more than 4, 000 blood samples a day, subjecting each to 10 or more tests. Automation has cut the cost of the analyses by about 90 percent.
The results so far have been astonishing, for hundreds of Swedes have learned that they have silent symptoms of disorders that neither they nor their physicians were aware of. Among them were iron-deficiency anemia, hypercholesterolemia, hypertension and diabetes.
The automated blood analysis apparatus was developed by Dr. Gunnar Lungner, 49-year-old associate professor of clinical chemistry at Goteborg University, and his borther, Ingmar, 39, the physician in charge of the chemical central laboratory of Stockholm’s Hospital for Infectious Diseases. The idea was conceived 15 years ago when Dr. Gunnar Jungner was working as clinical chemist in northern Sweden and was asked by local physician to devise a way of performing multiple analyses on a single blood sample. The design was ready in 1961. Consisting of calorimeters, pumps and other components, many of them American-made, the Jungner apparatus was set up here in Stockholm. Samples from Farmland Province are drawn into the automated system at 90 second intervals. The findings clatter forth in the form of number printed by an automatic typewriter.
The Jungners predict that advance knowledge about a person’s potential ailments by the chemical screening process will result in considerable savings in hospital and other medical costs. Thus, they point out, the blood analyses will actually turn out to cost nothing. In the beginning, the automated blood analyses ran into considerable opposition from some physicians who had no faith in machines and saw no need for so many tests. Some "laboratory technicians who saw their jobs threatened also protested. But the opposition is said to be waning. [br] The prediction process that the Jungners use is essentially ______.

选项 A、biological
B、physiological
C、chemical
D、biophysical

答案 C

解析事实细节题。化验是依靠化学的手段，因为两位发明人都是化学家，而且从最后一段的第一句话中也可以看出，The Jungners predict that advance knowledge about a person’s potential ailments by the chemical screening process will result in considerable savings in hospital and other medical costs．因此C是正确答案。
