73 - 76. soruları aşağıdaki parçaya göre cevaplayınız.
For over 3.8 billion years, biological evolution has served as the planet's ultimate research and development laboratory. Natural selection has rigorously tested, refined, and optimized structures, materials, and processes across millions of species. Today, an expanding field known as biomimicry seeks to harness these evolutionary masterworks to solve complex human engineering challenges. Rather than exploiting nature merely as a source of raw materials, biomimetic scientists view living organisms as invaluable design mentors. A classic illustration is the Japanese Shinkansen bullet train. When emerging from narrow tunnels at tremendous velocities, earlier models generated a thunderous atmospheric sonic boom that rattled nearby residential windows. Engineer Eiji Nakatsu, an avid birdwatcher, observed that the kingfisher dives smoothly from air into dense water with virtually no splash thanks to its elongated, streamlined beak. By redesigning the train's nose cone to mimic the kingfisher's aerodynamic geometry, engineers not only eradicated the noise pollution, but also reduced electrical power consumption by fifteen percent. Redesigning the train's nose cone after the kingfisher's beak resulted in ----.
- A)both acoustic noise reduction and notable improvements in energy efficiency
- B)a substantial reduction in maximum operating speed for passenger safety
- C)the complete replacement of electrical locomotives with magnetic levitation
- D)higher passenger ticket prices due to expensive aerodynamic maintenance
- E)a heavier locomotive structure that required reinforced railway bridges

Doğru cevap: A) both acoustic noise reduction and notable improvements in energy efficiency
Çözüm: Son cümlede gürültü kirliliğinin ortadan kaldırılmasının yanı sıra elektrik tüketiminde yüzde 15 tasarruf sağlandığı ("eradicated the noise pollution, but also reduced electrical power consumption by fifteen percent") belirtilmektedir.
