问题    Long ago men learned that the world of nature is built with mathematical exactness according to refined and powerful laws; every bee stokes its wings exactly 440 times a second to propel itself forty miles an hour; the eye of every fly has exactly 7,000 lenses; every spider’s thread is composed of 300 single threads.
   The progress of civilization itself can be measured by its range of mathematics. The early Egyptians know enough of geometry to build the pyramids and the Greeks used trigonometry to measure the circumference of the earth two thousand years before Columbus sailed. European civilization combined geometry and trigonometry with the decimal system of the Arabs to produce the maps with which the European explored the world. In a later century, mathematicians studied the pendulum (钟摆) of the newly invented clock and created the language of calculus to measure motion.
   The yardstick of measurement today must cover everything from units tinier than atoms to distance of millions of light years. Speed and accuracy are vital. Man can never send a racket to Mars unless he knows the exact distance to the planet. Since the slightest error could mean missing it by 30,000 miles. In navigating amid the planets and stars, man must have the help of some kind of machine calculators for fast and absolutely accurate information.
What can be inferred from the text?
选项 A、In ancient times people knew nothing about mathematics.
B、The power of nature used to have a great influence on man.
C、Progress in civilization demands ever better mathematical tools.
D、Technology plays an important role in information collection.
答案C
解析 推断题。根据最后一段最后一句“…man must have the help of some kind of machine calculators for fast and absolutely accurate information．”可以推断出，文明的发展需要更好的数学工具来支持。故选C。
