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. What problem did the earlier models of the Japanese Shinkansen bullet train encounter?
- A)They were incapable of reaching speeds exceeding one hundred kilometers per hour.
- B)Their engines frequently overheated during long cross-country journeys.
- C)They consumed too much fuel because of their excessive overall weight.
- D)Their wheels suffered rapid structural wear from high friction on tracks.
- E)They produced an intensely loud sonic boom upon exiting tunnels.
