Section A
According to a new school of scientists, technology has been overlooked as a force in expanding the horizons of scientific knowledge.【51】Science moves forward, they say, not so much through the insights of great men of genius but by more ordinary things like improved techniques and tools.【52】" In short, " a leader of the new school contends "the scientific revolution, as we call it, has been largely caused by the improvement, invention and use of a series of instruments that have expanded the reach of science in innumerable directions.
【53】Over the years, tools, and technology themselves as a source of fundamental innovation have largely been ignored by historians and philosophers of science. The modern school that hails technology argues that such masters as Galileo, Newton, Maxwell, and Einstein, and inventors such as Edison, attached great importance to and derived great benefit from, crafty information and technological devices of different kinds that were used in scientific experiments.
The centerpiece of the argument for technology was an analysis of Galileo’s role at the start of the scientific revolution. The wisdom of the day was derived from Ptolemy, an astronomer of the second century, whose elaborate system of the sky put Earth at the center of all heavenly motion.【54】Galileo’s greatest glory was that in 1609 he was the first person to turn the newly invented telescope on the heavens to prove that the planets revolve around the sun rather than around the Earth. But the real hero of the story, according to the new school of scientists, were improvements in the machinery used for making eye-glasses.
Federal policy is necessarily involved in the technology vs. genius dispute.【55】Whether governments should increase financing for pure science at the expense of technology or vice versa often depends on the issue of which of the two is seen as the driving force.

Applied research, undertaken to solve specific practical problems, has an immediate attractiveness because the results can be seen and enjoyed. For practical reasons, the sums spent on applied research in any country always far exceed those for basic research, and the proportions are more unequal in the less developed countries. Leaving aside the funds devoted to research by industry--which is naturally far more concerned with applied aspects because these increase profits quickly--the funds the U.S. Government allots to basic research currently amount to about 7 percent of its overall research and development funds. Unless adequate safeguards are provided, applied research invariably tends to drive out basic. Then, as Dr. Waterman has pointed out, "Developments will inevitably be undertaken prematurely, career incentives will gravitate strongly toward applied science, and the opportunities for making major scientific discoveries will be lost. Unfortunately, pressures to emphasize new developments, without corresponding emphasis upon pure science tend to degrade the quality of the nation% technology in the long run, rather than to improve it."
The title below that best expresses the ideas of this passage is ______.
A．Roentgen's Ignorance of X-rays
B．The Attractiveness of Applied Research
C．The Importance of Basic Research
D．Basic Research vs. Applied Research
Italian experts are proposing a dramatic new solution to the watery threat facing the city of Venice. Rather than battling to keep the sea out—they want to use it to help raise the sinking island-city.
(33) The scheme would~ involve pumping huge quantities of sea water into the ground beneath Venice down 12 pipes each of which would be 700m long. The sea water would make the sand beneath the city expand lifting Venice by 30cra in 10 years.
(34)Now, a panel of engineers and geologists from the respected University of Padua have come up with the new scheme costing just a fraction of that—100m euro.
It says the plan would help raise Venice by almost as much as it has sunk over the past three centuries. The professor leading the project says it is not an alternative to the floodgates - but would work in collaboration with them. Be now wants to carry out a trial to see if the theory would work in practice.
Not everyone is convinced. (35) One expert—who helped stabilize the leaning Tower of Pisa—described the scheme as pure science fiction and warned it could damage the fragile structure of Venice. But the city's mayor is interested. He says it is time to look again at how to raise the city—and is convinced that the technology exists to make it a reality.

A．Building floodgates to keep the sea out.
B．Stopping the sea level rising.
C．Raising the sinking city of Venice.
D．Saving the city from flooding.
